KK from Malaysia sent me his Zodiac. He doesn’t want a service, as he says it’s been serviced recently. The watch doesn’t make it across the date change, and just stops.
The watch has a fast beating 10 beats per second movement, and an unusual crown position.
Looks like whoever serviced the watch had their timegrapher stolen the night before 😉
I take the movement out and remove the day ring. I’ll take out the whole date mechanism, and put everything back clean and lubricated to make sure that it works as it should.
This movement doesn’t have its clutch on the canon pinion, but on the second (not centre) wheel. I notice that the clutch isn’t gripping properly, and that might be the reasons it stops when it’s time for the date change – the clutch just slips. That means I have to turn the movement over and take the second wheel out.
I take off the auto winder, and remove the wheel bridge, so that I can take out the second wheel (already removed and on the side in this photo).
When removing the clutch wheel, the pinion separates from the wheel. Not what I bargained for, but not a huge problem.
Out comes the staking set. With a large stake, I press the wheel back on to the pinion.
In the next step, I re-rivet the pinion to the wheel.
I have re-tightened the clutch pinion, and now press it back on. One day, I will get myself one of those £700 Boley staking sets 😉
Now I can put the movement back together, and I adjust it. That looks better, but the amplitude could be a bit stronger…
The watch now changes date without stopping, and all is well. Back to Malaysia it goes!
