Question about TAG behaviour (A7750)

[jarpo]

Hi The Zigmeister,

After almost one year wearing it regularly, with incredible accuracy and good performance, my TAG Carrera started causing problems last monday. (A7750 28800bph)

This is the description of the facts:

1) From the very beginning the crown has been quite hard to turn when widing. So I tried to keep it working continuosly as much as possible, and just with the "automatic winding".

2) It works well with the watch facing up, I need to check accuracy I hope to do it tonight, but I'm almost sure that no problem in this position.

**EDIT**: I left the watch sitting in my table last night, and after around 16 hours is keeping great time.

3) If I turn the watch, looking at the movement, I can see how the wheel that is always oscilating (with the spring) starts to loose "power" and finally stops completely. If I shake the watch it starts again, if I turn the watch again to face up it continues running fine.

Do you have an idea of what is happening?? I've never had this rep serviced

Thanks in advance and sorry for my poor technical vocabulary...

It sounds like the balance cap jewel in the mainplate (under the dial) has come loose. If it runs fine dial up and stops running dial down, then most likely the jewel is out of place causing the balance to stop working.

It could be something else, but this is the most likely problem from your description.
