I notice one of my watches are going way to slow IMHO.

Oupps, that is not good.



So I take out the tools.



Pull the bracelet off.



Put it in the case opener.



Off with the backcase.



I need some more tools.



Then a little fine adjustment.



At the third try it looks ok but a little low amplitude so maybe it's time for a service anyway.

It will be interesting to see how it runs at the wrist.
