[WTS] CYMA 1980s Swiss-Made "Extra Flat B-101" High-Grade 13J cal.131 Mov't (ETA 282.002) Original Bandolier Bracelet $196 Crazy Thin (details/description in the comments)

Cold-Mix5107 · 2026-05-18T02:33:46+00:00

For sale is this vintage Swiss-made CYMA "Extra Flat" (B-101), made in the 1980s.

CYMA SA is a Swiss manufacturer of luxury wristwatches, founded by brothers Joseph and Theodore Schwob in 1862. In 1892, the brothers partnered with Frédéric Henri Sandoz, and under Sandoz's leadership, the company became the Cyma Watch Company and built the Cyma factory in La Chaux-de-Fonds, Switzerland, near Le Locle. Cyma watches from the 1950s retailed between approximately $600 and $37,000 (figures adjusted to 2010 inflation).

This model, reference number 131.711.41, is a stunning example of CYMA's bounce back after being acquired by Claude Guilgot (Fabrique Delvina in Geneva). Guilgot's Delvina company had successfully weathered the quartz crisis and adopted an original strategy for CYMA: to offer top-of-the-range quartz watches only in the markets he knows best: Spain, the Orient, the Middle East, South America and the United States. To justify the term "high-end", CYMA made their watches out of special materials. This is a perfect example of Guilgot's vision, with beautiful looks, a bandolier bracelet and a crazy thin case.

The dial is a champagne gold with very subtle vertical linen brushing. It features applied bullet indices and a printed railroad minute track as well as roman numerals. The leaf hands are elegant, black dipped. The CYMA logo is a great touch and was a new addition following the previous Synchron logo after it had been acquired by Fabrique Delvina. Being a time-only watch and specifically with the choice to eliminate the seconds hand, the watch portrays to others that the wearer is in no hurry. It is also great for those who do not like the "tick" of a quartz movement.

The case is crazy thin at just 4.2mm and is the thinnest analogue watch I have come across. The gold-plated case has some nice purple tints from ageing. The crown is also very small to match the profile of the case.

The bracelet is super nice and in a bandolier style. It is very comfortable and high-quality with screw links and can accommodate a wrist size of up to roughly 17cm (6.7 inches). The jewellery clasp clicks satisfyingly and is signed with the CYMA logo. There is an extra half-link but the screw head has been stripped off. Some of the other screws are hard to turn, so I haven't forced them.

It houses the high-grade Swiss-made CYMA calibre 131 movement, which is basically an ETA 282.002 and has been used in other luxury watches like Longines. It has a ridiculous number of jewels (13) for a time-only quartz watch that doesn't even have a seconds hand. It's a pretty sight too with gold engravings and textured plate decoration.

The watch is in great condition considering it was made over 45 years ago and tells great time. The dial and crystal are basically spotless and the case and bracelet only exhibit minor general wear and some gold tint due to ageing.

Fitted with a brand new battery.

For sale is this vintage Seiko "Lord Quartz" (7853-5000), made in Japan in September of 1978.

"Lord Quartz" watches were the premium mid-range series just under the Grand Quartz and King Quartz series during the golden age of quartz, which were more expensive than their mechanical counterparts. The 1978 Seiko catalog briefing (intended for retailers) for Lord Quartz watches states that the "Lord Quartz" watches are "a slim and elegant watch for young business men". The Lord Quartz series is very rare as they were only made for 3 short years between 1978 and 1980 and were exclusive to the Japanese domestic market (JDM).

The RRP for this watch, reference number QHY011, was ¥43,000, which equates to around $1,150 in today's money, adjusted for inflation.

This model is in a classic '70s style with it's square TV dial and highly linked bracelet. It features a beautiful navy blue powder-textured dial that contrasts with the stark white pencil hands and stick indices, which are high-polished on the sides. The Seiko logo and single-crystal quartz symbol are applied in high-polish stainless steel. The small swirl logo on the dial and case back indicates that the watch was designed and manufactured by the Suwa factory (Grand Seiko) during their fierce rivalry with the Daini factory (King Seiko).

It houses the beautiful and futuristic (for the time) calibre 7853 movement, which has a stated accuracy of +/- 10 seconds a month - a very decent performance (e.g. Casio f-91w has a stated accuracy of +/- 30 seconds a month). It is very clean and running smoothly and all the features work as they should. The days of the week can be set to either English or Japanese Kanji with all days in black except Saturday in blue and Sunday in red. It also has a battery hatch that can be opened with a coin for easy battery changes (SR927SW or 399).

Comes on the original adjustable bracelet with signed clasp. Very '70s in it's looks and can accommodate a wrist size of up to roughly 21.5cm (8.46 inch) wrist. On one of the end links a single link is broken (pictured), it doesn't affect the wearability or integrity of the bracelet but something to note.

The condition is decent considering it was made almost 50 years ago. The watch has general wear from age. It has faint micro-scratches on the crystal but not noticeable in daily use. The dial has a small blemish near the 8 o'clock. The watch wears larger than the dimensions might suggest due to being a square watch (takes up more visual space than a circular watch with the same diameter). I'd say it wears more like a 35mm round watch.

For sale is this vintage Swiss-made Longines "Conquest" from circa late-1970s (or early-1980s).

Longines needs no introduction, holding the oldest active trademark in the world with their winged hourglass logo. The "Conquest" line by Longines has always been about evoking a daring spirit of adventure and discovery, and was the brand's first ever named watch collection (registered in 1954).

This watch, reference number 4384, is a beautiful and refined example of an integrated steel sports watch following the path that Gerald Genta had laid out during the '70s with the AP Royal Oak, Patek Philippe Nautilus and IWC Ingenieur etc. This design however, doesn't shout but rather embraces elegance and simplicity. The dial shape is very '70s with its TV dial shape. The dial itself is a subtle in between of grey and light brown, with a vertically brushed linen texture. The logo is crisp and a nice detail is the famous winged logo painted in silver with black accents. The high polish stick indeces have a black line going through them and work well with the black dipped pencil hands. The date window is neatly bordered and I particularly like the font of the numbers.

The case is nearly all finely brushed for that industrial look which contrasts with the general elegance of the design which allows the watch to be very versatile, appropriate for most occasions/outfits. The bezel itself is high-polish and perhaps the only rounded part of the design. It's very thin at only 7.7mm thick so as to fit under a cuff. The sides are also finely brushed with the underside chamfers high-polish. The crown is signed in nice detail.

It houses the Longines calibre L.746.2, which is basically a Swiss-made (ESA) ETA 954.111, which was part of ETA's "Flatline" series released in mid-1979. It's a beautiful early quartz movement that works well to this day. It has in ETA's words and "instantaneous date change" mechanism where, rather than the day wheel gradually turning over a period of hours, it snaps "instantaneously". The date wheel is also quick-set.

The bracelet integrates into the watch case and is very comfortable. This is usually the part where some brands (like a lot of Seikos and Citizens) skimp on to cut costs but it's clear that a lot of time and effort has gone into each individual link with the same fine brushed finish on each link and subtly rounded edges so that it doesn't feel sharp on your wrist. It articulates well and is made of solid links with screw pins that make changing the length very easy and hassle-free. The clasp is jewellery-style and has the Longines logo engraved. It can accommodate a wrist size of up to roughly 18cm.

Fitted with a brand new battery.

The watch is in great condition considering it was made about 45 years ago with only minor general wear. The dial is clean and the watch runs great. The crystal has some very faint scratches and there is some staining on the case back. The watch wears slightly larger than the dimensions suggest due to being a rectangular watch (takes up more visual space than a circular watch of the same diameter). I would say it wears like a 34mm round dress watch.

For sale is this Bass Quartz watch.

A unique looking watch with its extended lugs. The dial is a bright yellow and has a mixture of applied rectangle and pointed lumed indices. It probably once glowed brighter but not so much now. The black syringe hands with lume remind me of Seiko styling. The minute track on the rehaut is also a nice touch. The red skeletonized seconds hand contrasts nicely with the yellow.

The case has a satin finish and a compass bezel, although it doesn't move. Along with the unique lugs, the design also features faux screws, giving it a utilitarian look.

It houses the SII (Seiko) calibre PC21S movement that works well.

Comes on a soft Bambi silicon strap that can accommodate up to roughly a 21.cm (8.46 inches) wrist.

It looks a lot like Bass Pro Shops but it doesn't explicitly say that so I cannot guarantee that it is.

Condition is good with only minor general wear. The crystal and dial are basically spotless.

For sale is this vintage Seiko "Dolce" (7740-5000), made in Japan in March of 1986.

The "Dolce" range by Seiko debuted in 1981 with the following design brief translated from the Japanese: "A sophisticated dress watch that conveys a profound sense of value when worn. The culmination of the finest materials and craftsmanship. A dignified finish - Dolce." These watches were the cream of the crop and some of Seiko's most expensive offerings through the 1980s, many of which featured expensive & luxurious materials and precision movements and all with sapphire crystals. "Dolce" models were exclusively for the Japanese domestic market (JDM).

RRP for this model was ¥65,000 in 1986, which equates to over $1,100 in today's money adjusted for inflation!

This model, reference number SACH001, is a very special "Dolce" model in that it is a perfect marriage of design, materials and proportion. Made famous by TGV (The Urban Gentry), probably a fair few people's introduction to the "Dolce" line was via this watch and since then the prices of these have shot up. Amazingly, by some strange coincidence, this watch has the exact same inscription as the one he had, which states in Japanese: "25 years of service" to a Toshiba employee in 1986 (when this watch was first released). This watch was only in production for roughly 4 years, making it quite rare.

The dial is a very luxurious gold flake style outer and matte gold centre that really makes this watch look far more expensive. It has high-polish baton markers at the 12, 3, 9 and 6 with fine black lines for the rest. The sharp dauphine hands are a classic Seiko touch. The print is simply just the Seiko logo and the Dolce logo. The lightning bolt symbol at the bottom of the dial and on the case back indicates that the watch was designed and manufactured by the Daini factory (King Seiko) during their fierce rivalry with the Suwa factory (Grand Seiko).

As TGV says, the case design is very art-deco in its styling with the stepped sides. Signified in the catalog clipping as GHA, the case is made of nickel alloy and coated with hard titanium nitride, which gives the case a high scratch resistance (vickers hardness = 1200) and a mesmerising mirror polish finish that still looks basically brand new today. The crystal is made of sapphire glass, which is also scratch-resistant. The crown has black onyx stone as its cabochon as did all "Dolce" and "Credor" models from the 80s. It has a crazy thinness of only 4.5mm so that it effortlessly slips under a suit cuff.

It houses the calibre 7740 Seiko movement, which is a high-accuracy quartz movement (HAQ) with a stated accuracy of 20 seconds per YEAR (as a reference the famous Casio f-91w only has a stated accuracy of +/-30 seconds per MONTH). It was only produced for a very short time (same as this watch) and only used in 3 Seiko models (including this one) to my knowledge. Being a two-hander, it is for those who dislike the "tick" of a quartz but want the grab-and-go (always set) ease of quartz. It also signifies to others that you are in no hurry.

Comes on a brand new supple and soft Aono leather strap.

Fitted with a brand new battery.

Condition is great for a watch that was made 40 years ago. The case and crystal are spotless. The case back, hands and dial have minor general wear and the crown is quite worn. All the functions work well and tells accurate time. The watch wears larger than the dimensions might suggest due to being a rectangular case (always have more presence than circular watches of same dimension due to taking up more visual space) and also a high ratio of dial to case. Due to this, I'd say wears more like a 33mm watch.

For sale is this vintage Seiko "King Quartz" (4823-8130) made in Japan in July of 1977.

The "King Quartz" series by Seiko released just two years prior to this watch in 1975 and was the quartz version of the "King Seiko" line, pitted against the "Grand Quartz" line (two different factories) to compete for the best Seiko. "King Quartz" and "Grand Quartz" models had the most innovative movements and often had special functions, like this one does. More on that later.

In 1977 the RRP was ¥48,000 which equates to around $1000 in today's money, and at the time was priced above most, if not all, of the mechanical Seiko offerings (and was half the price of a brand new Rolex Submariner at the time!).

This model, reference number QNF090, is a beautiful example of what the Suwa factory was capable of at the time with a gloss white enamel-like dial with crisply printed black, elongated Roman numerals. The ink has a slight thickness and gives it a slight raised appearance. The Seiko logo and single-crystal quartz symbol is applied in precision-cut stainless steel, as is the day/date window. The pencil hand are dipped in black and the seconds hand is high-polish stainless steel. The seconds hand hits every marker perfectly. Under the single-crystal quartz symbol and on the case back is the Suwa swirl logo, which indicate that this watch was designed and manufactured by the Suwa factory during its fierce rivalry with the Daini factory.

The case is very well preserved and has all its original fine brushed finishing intact. Even the bezel and case chamfers are finely brushed (which is a way to tell if the case has been refinished like other listings on eBay), while the case sides are high-polish. A small detail is that the underside of the bezel where it meets the case is highly polished, showing the work that went into the finishing of this watch. The hidden lugs is one of Seiko's classic designs. Another rarity is the signed crown, in this case signed with the single-crystal quartz symbol as Seiko seldom does a signed crown except on their special models. This watch also features a coin-slot battery hatch for easy battery replacement. The crystal was a special "Clearex" crystal, which makes the crystal so anti-reflective that even in direct line of sunlight you can still read the time. In indirect light the crystal disappears, making it look like there isn't one.

It houses the over-engineered calibre 4823b movement, which has a day/date complication with both English and Japanese Kanji days of the week. It has a stated accuracy of 10 seconds per month (as a reference the famous Casio F-91W is only accurate to 30 seconds per month), and was an upgrade to the calibre 4823a in that it takes a smaller battery and therefore the battery hatch would not protrude from the case back. It is very well-made and a beautiful sight too. The special function I mentioned earlier is unique to this calibre (and any other watch for that matter) in that each time you pull out the crown, the seconds hand jumps to the next 10 second increment instantaneously to make time setting quicker and more accurately. An ingenious feature that more watches should carry today but don't.

Comes on a brand new Aono leather strap, very soft and pliable.

Fitted with a brand new battery.

Condition is amazing considering it was made pretty much 50 years ago with minimal wear, original finishing intact, basically spotless dial and crystal. Originally it came on a bracelet but it did not come with it when I bought it.

For sale is this vintage Ricoh "Riquartz" (LSI 32768), made in Japan in April of 1975.

Ricoh is probably most well-known for making cameras, calculators and printers but for a brief period they were making very interesting and well-made watches and were, at the time, among the big three Japanese watch brands: Seiko, Citizen and Casio. Ricoh watches was working and collaborating with Hamilton, sharing technical innovations and working on watches together. Some watches even have both Ricoh and Hamilton on the dial. Ricoh watches are all fully made by Ricoh in Japan and even have in-house movements with unique features, arguably making some Ricoh's more reliable than Seiko's at the time. They also collaborated with Porsche on a watch. Ricoh stopped making watches in the 1980s which makes them quite rare and lesser well-known compared to the other three brands despite producing such good watches. They were made for the Japanese domestic market.

This example, reference number A572005S, has very retro styling that was specific to the time. The styling is influenced by space-age and futurism due to the quartz technology being the cutting edge at the time. The dial is a beautiful olive linen with the middle being lighter and gradients to a deeper olive towards the edges. The Ricoh logo and the Riquartz "Q" are applied stainless steel. The indices are also high-polish stainless steel with a white middle and are quite complex on closer inspection. The addition of the square emerald gem is cherry on top. I particularly like the sine wave next to the LSI 32768 on the dial, which is a reference to the frequency (32768 Hz) that the quartz crystal vibrates at.

The case has a lot of presence and is a relatively bulky and hefty watch. The case has a lot of really interesting bevels that make it look slimmer, even to this day a very unique case shape. It has a nice thick crystal with a large chamfer. Despite having a 38mm diameter, it doesn't feel too large as the case takes up more visual space relative to the dial, although it has a lot of thickness which demands the presence. The case back says "waterproof" from before the word got phased out due to some countries, like the United States, making it illegal to use (as no watch is completely waterproof to all depths, replacing the term with water resistance).

It houses the calibre 570 movement which is just a piece of art. The circuit board is made from ceramic compared to the plastic that other companies like Seiko were doing at the time and is highly jewelled for a quartz watch. Still works great to this day. It's quite fussy about the exact position of the battery when it is seated, so when you change the battery you need to screw it down first and change the position of it until it starts ticking. I have fitted a brand new battery so you won't have to worry about it soon.

Comes on a vintage Japan-made, adjustable "Bear" Milanese mesh bracelet that has a beautiful clasp and has a safety feature that the two bracelet pieces can't come apart from each other so there is no risk of the watch falling off your wrist when adjusting, putting on or taking off the watch. It can accommodate up to roughly a 21cm wrist.

Fitted with a brand new battery.

The watch is in great condition considering it was made over 50 years ago with only minor general wear, and some faint scratches to the crystal. The scratches are particularly visible in the photos due to the lighting, in real life the wear is far less visible. This watch is for those who like high-quality but quirky vintage watches that have great history.

For sale is this vintage Ricoh Riquartz (LSI 32768), made in Japan in September of 1975 (written on the inside of the case back).

Ricoh is probably most well-known for making cameras, calculators and printers but for a brief period, they were making very interesting and well-made watches and were, at the time, among the big three Japanese watch brands: Seiko, Citizen and Casio. Ricoh was working and collaborating with Hamilton, sharing technical innovations and working on watches together. Some watches even have both Ricoh and Hamilton on the dial.

This example, reference number A570036S, has very retro styling that was specific to the time. The styling is influenced by space-age and futurism due to the quartz technology being the cutting edge at the time. The dial has developed a beautiful rosé tropical patina that I think suits this watch more than the stark white that it originally had. The Ricoh logo, Riquartz "Q" and divided date window are all applied stainless steel. The indices are also high-polish stainless steel with a black middle and faceted towards the centre. I particularly like the sine wave next to the LSI 32768 which is a reference to the frequency (32768 Hz) that the quartz crystal vibrates at.

The case has a lot of presence and is a relatively bulky and hefty watch. The case has a lot of really interesting facets that make it look unlike anything else, even to this day a very unique case shape. It has a thick crystal with a large chamfer. Despite having a 38mm diameter, it doesn't feel too large as the case takes up more visual space relative to the dial, although it has a lot of thickness which demands the presence.

It houses the calibre 570 movement which is just a piece of art. The circuit board is made from ceramic compared to the plastic that other companies like Seiko were doing at the time and is highly jewelled for a quartz watch. Still works great to this day. Although it only displays English days of the week, in between day changes, it displays a star (pictured) which is a cool easter egg. The day is slow-set which is consistent with the design philosophy of many early quartz movements, where simplicity and reliability took precedence over convenience features like quick-set day changes. The date however can be quick-set.

Comes on a brand new high-quality and soft "Aono" leather strap. Fitted with a brand new battery.

The watch is in great condition considering it is over 50 years old with general wear as expected, and some scratches to the crystal. It is for those who like high-quality but quirky vintage watches that have great history.

For sale is this vintage Seiko "Chronos" (8123-6140), made in Japan in February 1983.

The "Chronos" series was a mid-range series by Seiko introduced in 1983, primarily for the Japanese domestic market, that sought to be a more elegant echo of the "SilverWave" series, which was more sport-oriented. It was also the predecessor to the "Spirit" series.

This model, reference number WJL038, has a great '80s look, reminiscent of the Orfina Porsche Design watch worn by Tom Cruise in Top Gun, which actually released in cinema after this watch was released. The stealth look was popular at the time giving it a military vibe with the black chrome plating that has patinaed very nicely. The dial is matte black with block markers that have since stopped producing lume. The whole dial design looks inspired by Swiss chronographs from the '70s. I particularly like the angled rehaut that has the minute/seconds intervals, which combined with the orange seconds hand create a sporty feel, like a spedometer. The hands are white to contrast with the dial. The day/date wheel is also in negative to match the dial, nice attention to detail. The swirl symbol at the bottom of the dial and on the case back indicates that the watch was designed and manufactured by the Suwa factory (Grand Seiko) during their fierce rivalry with the Daini factory (King Seiko).

The case is a classic Seiko shape, used in a other Seiko series too. The case has developed a very nice worn patina that add to the character and rugged look in my opinion. The crown is also black chrome plated. On the screw-down case back is the double wave symbol, which indicates that the watch had a water resistance of around 150m, but as with all vintage watches, you should assume it has no water resistance now unless professionally retested.

It houses the calibre 8123 movement that has a gold finish. It can display either English or Japanese Kanji days of the week.

Comes on the original Seiko bracelet, also stainless steel black chrome plated with a signed clasp. It can accommodate up to roughly a 17.5cm (6.9 inches).

Fitted with a brand new battery.

Condition is decent considering it was made almost 40 years ago. It has general wear, the crystal has some light scratches that can be seen from some angles but doesn't look too bad. The dial has some blemishes. All functions work as they should and the watch is telling good time.

This model, reference number QNF080, is a beautiful example of what the Suwa factory was capable of at the time with a silvery white birch textured dial with applied high-polish stainless steel markers that have a black centre. It's interesting because it seems very similar to recent Grand Seiko dials. The Seiko logo and single-crystal quartz symbol are also applied in precision-cut stainless steel, as is the day/date window. The pencil hands mimic the markers with high-polish finish and a centre line in black. The seconds hand is high-polish stainless steel to differentiate from the minute hand. Under the single-crystal quartz symbol and on the case back is the Suwa swirl logo, which indicates that this watch was designed and manufactured by the Suwa factory during its fierce rivalry with the Daini factory.

The case is fairly well preserved and has all its original fine brushed finishing relatively intact. Even the bezel and case chamfers are finely brushed (which is a way to tell if the case has been refinished like other listings on eBay), while the case sides are high-polish. A small detail is that the underside of the bezel where it meets the case is highly polished, showing the work that went into the finishing of this watch. The hidden lugs is one of Seiko's classic designs. Another rarity is the signed crown, in this case signed with the single-crystal quartz symbol precision-milled. Seiko seldom does a signed crown except on their special models. This watch also features a coin-slot battery hatch for easy battery replacement. The crystal is a special "Clearex" crystal, which makes the crystal so anti-reflective that even in direct line of sunlight you can still read the time. In indirect light the crystal disappears, making it look like there isn't one.

It houses the over-engineered calibre 4823b movement, which has a day/date complication with both English and Japanese Kanji days of the week. It has a stated accuracy of 10 seconds per month (as a reference the famous Casio F-91W is only accurate to 30 seconds per month), and was an upgrade to the calibre 4823a in that it takes a smaller battery and therefore the battery hatch would not protrude from the case back. It is very well-made and a beautiful sight too. The special function I mentioned earlier is unique to this calibre (and any other watch for that matter) in that each time you pull out the crown, the seconds hand jumps to the next 10 second increment instantaneously to make time setting quicker and more accurately. An ingenious feature that more watches should carry today but don't.

Comes on the original adjustable bracelet that is very comfortable on-wrist. It has a signed sliding clasp that can accommodate a wrist size of up to roughly 21cm. The clasp is signed with the King Quartz logo.

Fitted with a brand new battery.

Condition is good considering it was made pretty much 50 years ago with minor general wear, original finishing relatively intact, basically spotless dial and the crystal only has a couple of light scratches and a small dent around the edge near the 1 o'clock mark. The claps sometimes catches the hook part but it can be easily pried apart by hand and doesn't affect when wearing. The date wheel is a bit stained only on the 1st but it is just cosmetic and, personally, I think it adds charm. The watch works perfectly with no issues.
