Movement stops .. and then starts again after a while

[bjarneb]

I bought a AD Royal Oak on a shopping mall in Malaysia a while ago. A beauteful peace of art actually, and I payed $600 for it. The seller claimed it was from JF factory.

I have a problem though. I goes like a charm for some days but suddenly it stop. Makes no difference if I wind it manually or shake it like if I was epileptic. Then suddenly it starts working again after several hours. Not too keen to take it to a watch dealer here since it is obviously is a fake watch. But will do if that is the only solution to make it work fine since it is way too cool to throw away. What would a wise man do?

I don’t know of a watchsmith in Norway, but there are plenty of options in Europe. @Ado213 UK, @slaughterer Germany, @SSTEEL Finland, @Natas78 Belgium.

Thanks a lot Sogeha !
I might try my local one and hope he doesn't throw me out of the shop .. If he does I will contact the Belgium one, I travel there several times every year.

These modified A7750 movements that transfer the native running seconds from @9 to @12 are quite problematic sadly.

So this is not something a watchsmith would be able to fix fast and easy? It is basicaly a bad movement?

It can be fixed. SSTEEL has mine with the same movement. Send it to him and he'll fix it for you.

You’ve got a JF watch apparently yes that’s true.

The issue like my betters above have pointed out is the A7750 sec@12 movement. It can be a problematic movement due to the accumulated friction in the transfer gears and the possible lack of lubrication in the friction areas.
The movement has indeed gotten better in the hobby in the recent years and are fairly decent. Yours could be a piece with poor lubrication or dirt in it. Yes the design of the movement isn’t ideal but there are ways to overcome it by service and proper lubrication, using an extra jewel or a better mainspring.

Thanks alot for the recommendation of using SSTEEL !!

He has fixed the watch now and the whole process was such a good experience that I almost hope it breaks down again so I can use his services one more time
Thumbs up for an extremly service minded and great watchsmith!

Shhhhhhhhh don’t tell everyone. SSTEEL is our secret here.....

From personal experience, intermittent stopping has 99% been due to something dilocating (often screw loose) and lodging itself in the works.

While ssteel is one of the best, don't be surprised if something else goes wrong in the future. That movement is not known for it's longevity.
