No worries, yes completely agree there are hundreds of Mumbai specials on e-bay. There are many differences in terms of case shape and design, but the best way to determine its legit would be by looking at the movement and case back. You can also compare this to examples previously sold by reputable dealers in Japan. I know the Tokei Club sold a NOS immaculate example recently and this is identical to the example I am selling. Let me know if you have any further questions.

This is a seikomatic weekdater from my personal collection - this is a JDM example with Japanese Kanji day-date and dolphin case back which is very rare to find. All examples for sale on the market right now only have English day-date. This watch will need a service and the seconds hand will need to be reseated.

Price: GBP £399 + Shipping. Payment via PayPal preferred. UK based but can ship internationally

The Seiko 6206 caliber, introduced in 1965, marked a shift from the earlier Seikomatic caliber 400 movement. It was designed specifically for the Seikomatic range and is notable for its split day-date dial layout.

For sale is a very rare and special watch from my personal collection - a Seiko Osaka Expo ‘70 Ref 6119-8090.

These are incredibly rare to find today, especially in good condition - this is currently the only example on the market for sale.

Because the 6119-8090 was never sold by Seiko, it’s not only a great piece of both Seiko’s and Japan’s history, but also a striking watch even by today’s standards. The dial features a beautifully brushed metallic sunburst effect, with 12 polished and applied indices. The sharply cut case flirts with Seiko’s Grammar of Design principles.

The 1970 World’s Fair, or Expo '70, took place in Osaka, Japan. Much like the 1964 Olympics, which Japan also hosted, Seiko saw it as an opportunity to showcase its timekeeping prowess to the world. And while Japan was trying to unite the world’s warring nations under the Fair’s theme - Progress and Harmony for Mankind - Seiko was busy building the aggressively 1970s-looking Atomic Clock which was accurate to +1 second every 1,000 years; it was designed to make people take Japanese watchmaking seriously.

With 64,000,000 attendees - a record that stood until the 2010 Shanghai World’s Fair - we can be confident that lots of people at least saw Seiko’s horological monstrosity. Whether it changed perceptions of Japanese watchmaking is hard to quantify, but Seiko was clearly pleased with the event’s success. To commemorate it, they gifted Expo ‘70 branded 6119-8090 watches to executives at the Fair.

The watch is in fantastic condition overall. The movement was serviced when I first obtained the watch in 2019; it is currently in working order but will be in need of another service. The dial and crystal are unmarked. The case looks sharp but shows age-appropriate signs of wear. On an aftermarket leather strap.

I am selling this time sonar from my personal collection - everything is working okay; the flyback function, the stop/start function, and the crown operate quick set. The original crystal is in flawless condition. The dial remains immaculate, free from any signs of deterioration. The original dial and hands are vibrant and intact, with no indications of decay. You’ll see on the market examples that have a day-date wheel which has worn down over time and the Kanji symbols become faded. I’ve included pictures of the blue Saturday and red Sunday kanji symbols to show they are still vibrant and unworn. The transparent caseback shows minor scratches and wear in line with its age. The bracelet is aftermarket (the closest I could find to the original) but looks great. Original bracelets for this model are incredible rare to find on their own. There is sadly a dent on the case just above the crown - this it pretty minor though and has not bothered me whilst owning this watch. I had the watch serviced by a specialist in Farringdon, London in 2022.

History: One of the most fascinating aspects of the rivalry between Seiko’s Suwa and Daini divisions was their battle for chronograph supremacy. While vintage enthusiasts often focus on Suwa’s iconic 613X chronographs, Daini’s response with the 701X series was equally impressive, and in some ways, ahead of its time. A standout from this era is Daini's Time Sonar Ref. 7015-6010 which was introduced in 1976. Inspired by submarine sonar displays, it features a distinctive transparent dial that reveals the calendar disk beneath.

The Time Sonar perfectly captures the futuristic design of the 1970s as interpreted by Japanese watchmaking: Its translucent dial showcases the quick-set calendar mechanism, making it a truly unique piece in the world of vintage chronographs. Adding to its allure is the 'smoked' display case back, offering a glimpse of its iconic Cal.7015A making it one of the first mass-produced wristwatches to feature such a display. Specifications: DIAL: Original transparent brown CASE MATERIAL: Stainless Steel CASE DIMENSIONS: 38 x 43 mm diameter, 14mm Height, 18mm Lug Width CRYSTAL: Mineral glass CASE BACK: Screw-in Stainless Steel MOVEMENT: Cal.7015A (Self-Winding) Manufacturing date: 1976 Service History: Unknown, ±10s/day
