How often do I need to change the battery for C3 MKI/MKII you know? Coz I had a bad experience with my Cartier, didnt check or change the battery for years (be exact more than 10 years) & finally decided to do so, cost me a bomb (300 pounds) & waited for 8 weeks. They had to replace a lot of parts (had to order parts from France or somewhere). I know I know, it's my fault, promise wont do it again : P .
Can I ask my local watch shops to do it? Or is it better & safer to send it back to CW?
Pls advise.
Much of the battery life will depend on how much use the chrono function gets. You can drain a battery in 6-12 months if the chrono is used a lot. That said...initial battery life should be somewhere between 3 -5 years. Subsequent life about every 2-3 years or so. These are averages and much depends on the chrono usage.
The reason for the shorter time frame of subsequent batteries is that a movement collects dirt/dust etc. and oils on the mechanicals dry as the watch ages, causing more drain on the battery.
A local qualified watchmaker will have no trouble changing a battery in a C3. Just make sure they are able to pressure test for water resistance as well, when the time comes.
