I have a CAF1010, which is an ana-digi model (ETA E20.321), and I plan on sending it to TAG at some point to have the battery replaced, gaskets checked / replaced and the exterior cleaned, as it is a bit dirty from the previous owner.

As far as I can tell, the watch is running perfectly with no issues, the digital display is a bit dim for my liking, but that’s probably just because it’s a negative display and I’m used to positive displays.

My questions are, is the complete service worth…

M1 partial maintenance vs M2 complete service for quartz chronograph?
