I have a OMEGA Seamaster Professional 300 ref. 2541.80.00 with a Cal.1438 which I haven't used for weeks, I've worn my Speedmaster most of the time and an Applewatch (i know :)).
Last week i checked the time and adjusted the date and everything looked fine, no 4 sec jumps etc.(don't know the age of the battery).
Today the watch had stopped, well it looked like the second juddered a little bit, but it didn't move.
I assumed it was the battery and since I had a brand new one at hand I decided to change it.
After I fitted the new battery it's been working fine.
The strange thing is that the voltage on the old battery was fine, so I was wondering what could have caused it to stop?.
Has anyone else experienced this?.
