Hi!!!
I recently got a submariner rep, the movement is a JH3135.
The date wheel was stuck so i opened the watch, removed hands, some parts, got the wheel back and managed to have it working
but now i have a very hard time calibrating the watch.
I use tg timer on a laptop with a good microphone.
i tuned the 2 beat and the rate and managed to get good results :
but i have a very strange problem :
my watch keeps good time at night but looses 10 minute at day...
yesterday at 7pm i set the watch to correct time and fully rewind it.
i checked the calibration, it's ok (4 s/d)
i put the watch in a quiet place.
in the morning at 7am the watch is ok (maybe 1 min off).
I leave the watch quiet.
on the evening, at 7pm, the watch is 10 min late !!!!
and when i check the calibration, it seems ok !!!
So at somes times i lost 10 min but then the watch went to is normal speed ?
I'm really lost here...
