I realize the answer to this question really depends on a lot of factors, but I'm curious if people have any thoughts on what sort of accuracy one can expect from a vintage watch?
I have a small, lovely little omega from the late 50's/early 60's with a 30T2 SC RG chronometre movement. I had it serviced in Hong Kong to get it working again(belonged to my girlfriend's grandfather) and then again here in the US to replace the scratched up crystal(don't worry, saved the original).
Dial up, it's gaining about five minutes a day, closer to about one minute a day if resting face down. Should I have it serviced again? in hindsight, the person I last sent the watch to may have not been as skilled as advertised. It's perhaps also worth mentioning that I do quite a bit of mild cycling, commuting around the city, so perhaps some of the inaccuracy I'm experiencing is due to daily bumps and shock?
I'm reluctant to have it serviced for a third time in one year(won't be sending it back to the last person I dealt with though), but also don't want to damage the movement if things really are in need of attention. Modernity being what it is, I can live with a finicky watch that needs to be set every day. What would you do in this instance?
