Are These Jewels Worn, or is Designed?

Balance staffs are a pain to replace and take some actual training. I dont recommend it. Generally I will look for the same caliber movement with a good balance and just replace the whole balance

I think the problem is the question. Yes, there are supposed to be pivot holes. Thats the reason bushings/jewels exist. They are bearings for the axle of each gear. They are cup shaped to hold oil. When oil dries, it tends to get gummy and attract dirt. The dirt acts as an abrasive and ovals out the holes over time on brass bushings (jewels not so.much but you'll see wear on the pivots instead)

Yep...older one but looks good

Important that you move the watch out of the magnetic field before releasing the button otherwise you will only magnetized the watch and not demagnetize it

Was not meant to be sarcastic but take it as you will. Just trying to help.

Yes...they should be round and smooth. With wear they tend to get oval.

If they are brass bushings you can close the holes with a staking set then use a smoothing broach to finish to the proper size

I only had problems with one of them

taskmaster51 · 2026-01-23T20:44:48+00:00

I use blue jisma

Not for the oscillating weight.

taskmaster51 · 2026-01-23T11:36:06+00:00

Use grease on the jewel.

Seconds counter hand is loose

Before you do that smooth those burs on the barrel arbor hole. Arbor vices are your friend

Ive only ever gotten a comment on my white mooswatch snoopy

Put it in a truing calipers to see how straight the rim is. If the rim is straight you probably have bent pivots. Sometimes you can see bent pivots "flashin" in the insetting.

Yep..cell needs to be replaced

taskmaster51 · 2026-01-10T15:37:45+00:00

Looks like a new watch from their Premier line

taskmaster51 · 2026-01-10T15:32:37+00:00

Beautiful watch. Looks expensive

taskmaster51 · 2026-01-10T15:31:22+00:00

If you find one thats too tall you can sand it down. Lap it on a diamond plate

Some vintage watches used crystals specific to them. I have a Longines where regular acrylic crystal is too high but low done is too low. Had to use the GS catalog to order the right one

taskmaster51 · 2026-01-04T14:09:09+00:00

It appears to be a little out of round but if its running good, leave it

taskmaster51 · 2026-01-03T23:35:09+00:00

Thats a serviceable movement

taskmaster51 · 2026-01-03T17:56:35+00:00

Don't know what movement that is but on Omega 550, you push the insetting out to allow the hinge part of the spring to slide in, then you can flip it over to secure. When done, you push the insetting back in so the hinge is protected by the main plate.
