First of all, please excuse my absolute lack of knowledge on this subject. I just love wearing different watches but know very little about how they work when the back comes off.
I have a Tawatec tritium diver with a Ronda 516 movement ( I would need to confirm the number) that I've had for about 8/9 years. I just love this watch even though it's pretty battered and scratched as its worn 24/7 but its about the only watch I can see clearly during the day and at night.
It packed in recently so I was just wondering is it expensive to replace the module and does anyone on here do this type of work.
