Help please how Zenith balance to accuracy

[Nyurick]

Hello everybody!

Could you help?

My watch is going too slow.

It's about -50 sec per day.

What should I rotate and where ?

Thanks in advance.

Please take it to a watchmaker for a service.

If you manage to regulate it without breaking it, it will still need a service...

if you still want to take a swing at it...

Agree with Matabog, besides I'm not sure how accurately you can regulate a watch without a time grapher, never tried, maybe get it to within 30 secs a day once the watch is actually worn and is working in different positions? not really worth risking damage as I see it.

Thanks everybody.

As a reminder this isn't your typical watch. Besides all the complications of an automatic chronograph it is also running at a speed twice as fast as a normal watch. Lubrication is definitely an issue for the 36,000 bph watch and if it hasn't been serviced in a while running slow may be an indication of that. You really need to have a timing machine Not just to look of the rate but to look at the amplitude verify the watch is running correctly and just needs to be regulated.

Then the screw is for fine adjustment regulation it has a floating stud holder and regulator pins are also floating so they're all independently movable. Lots of adjustments and lots of ways to go wrong without a timing machine.
