Hi everyone,
I have a question about an A7750 that's been acting up and was hoping someone more knowledgable could help. In short, it loses about 12-13 minutes a day, but there's a catch -- it only happens at a specific time (around 1030PM). For the rest of the day, it keeps on ticking normally and seems to be pretty darn accurate (+2s/d, except this issue).
I've had this particular movement for about three months and this problem surfaced about a week ago. I really have no idea what to make of it or what might be wrong. Maybe a gear somewhere is missing a few teeth? It's a bit puzzling because it's accurate, and suddenly, it's just behind 12 minutes.
Thanks!
Happy Thanksgiving.
