Hi,
I bought a watch with a A7750 two years ago and had it serviced by a trusted watchsmith on this forum since i love the watch and want to keep it. The watch have had a good power reserve of about 40h since that service.
I have lately noticed that the power reserve now is down to about 10h. The watch works great otherwise, i have not had it in water and i never use the chrono functions.
As a n00b my question is if this is something i can expect from a serviced watch?
