Spare part after service?! Need your help

Hello all,

This January I bought on eBay an Omega Seamaster to be serviced, hence I brought it to a watchmaker to ask for a full service.
He did serviced it, but when he gave me he told me that he found a "spare part" in the watch, and he didn't know what to do with it (check pictures, it's the metal circle).
Long story short, after the service, the watch stopped after 3 days of use (while it was on my wrist).
I brought back to him, he "fixed it" (I don't know exactly what he did) and after 4 days of use it stopped again :/
Now I am really thinking that the "spare part" maybe was in the watch for some reason ?
What do you think?

Thanks in advance.

Sorry, can you please explain me in noob words? 😀

I have no idea what that is, but I think you really need to look for a watchmaker who nows what he's doing!

Too late, he took quite a lot of money to service it, now he must fix it.
FYI - the picture of the caliber is before service

Well, I'd say he's had his chances and didn't succeed. You should get your money back and be allowed to take it els ware for a proper service.

The pictures of the caliber is before service. Actually now I can see in that pictures from where that "spare part" was taken! It's just outside the caliber!
The weird thing it's that the watch ran perfectly fine (I could not see any minutes +/-) for 3 days than it stopped!
Than got repaired, it ran super fine for other 4 days, than it stopped again

Yes that's unfortunate. I will try to get the money back (but I think that will be quite impossible) if he doesn't he will have to speak with my lawyer 😉

It looks to me like the case clamp (between the lower lugs) has been replaced by a loop of wire.

These calibres are usually held in by a pin between the upper lugs and a case clamp that has a big step to go down into the case slot. In side profile, it's flat under the screw, turns 90 degrees towards the front of the case, then turns 90 degrees outwards to go into the case slot. If all that is there now is a loop of wire, then it could be that the spare part 🤦 was added to sit behind the loop of wire and hold the movement in the case. Now it's not fitted, the movement is probably loose so, it can't charge with the auto winder.

It's all wrong and if it doesn't work, as has been said above, find someone who knows what they're doing. Don't persevere with this guy as who knows what else is wrong and you can be pretty sure he won't have been able to fix the loose rotor bearing, for example. These are a bit more difficult to service than a later automatic so if he has little experience he may struggle anyway.

Surely he offers a warranty and eventually a refund if he can't get it right?

Cheers, Chris

Thanks for the very clear explanation above!
Normally he just offers 1 year warranty, next week I will go to speak with him for a refund. I will keep you posted.

To be fair to him/her, everyone will get returns at some point but, you would have hoped that he would have tested it for, say two weeks, after it came back the first time and that doesn't seem to have happened. Parts are not readily available for these so, he may have been trying to keep it going without resorting to new parts - I don't know. It's not a good way to work but, sometimes this happens.

In the pre-service movement shot you posted, there was a rotor issue anyway as the rotor has not been correctly meshed with the part it drives. You see the part I am highlighting in red below (serial blanked out as it's a customer's watch), it should be completely hidden under the bridge with the serial on it when the rotor is over where yours is shown. It is not possible for it to have worked like that so, it had already been worked on badly. And note, this has a completely different case clamping system as it's earlier than yours by about 5-10 years.

Regards, Chris

Thanks Chris noted!
Next week I will try to post a picture after-service
Regards.
