Broken Center Jewel, Hamilton 974 "Click" to Login or Register 
posted
I bought this watch in my early days (3 months ago), and was satisfied that it simply ran. Then looking at it more closely, I noticed the broken center jewel, and am now pondering how to fix it. Since the jewel is in a setting, it would seem an easy matter to find a derelict 974 movement and rob the jewel from it -- so I may go shopping. But my question is whether it is as simple as this?

Here is a closer view -- I can see some sharp broken edges on the jewel that threaten to chew away on the center wheel pinion. I definitely will not run this watch till I get a proper center jewel. And these photos also indicate that a full cleaning and oiling is in order.

The way you are thinking is a simple fix. The problem is if you rob it from a fixable watch you have destroyed one to fix another. If you do find a donor movement / Jewel in setting. You will need make sure the replacement jewel and settings go / fit the pivot of the new watch.

I have a couple 992's movements that has the center wheel jewel. I have no idea if it would fit. But I'm sure some where on the site there is a movement parts list you should be able to find.

I don't have the heart to rob things from fixable movements. This watches time will come. Somewhere along the line I will accumulate enough random watch parts that an answer will offer itself.

Tom if you have a jeweling set you can remove the jewel from the seting and replace it.

Toms, e-mail me the serial number of your 974 and I will check my parts movements to see of there is a center jewel on a movement close in age to yours.
