Sentinel Watches

[roo]

Thank you both once again. I did notice the microadjustment was at maximum, which is interesting as the watch runs fast. It has done so since its last service, but because I use it rarely, it has not been a problem. I guess the watchmaker did this for some reason. It is an un-adjusted movement, so perhaps they regulated in an unfavorable orientation. Perhaps they let the apprentice loose on it. This last service was done by a reputable watch repairer. After the first service some years ago, I had worn the watch regularly for a while, and it kept good time, within 2 seconds per day.

I could not see any markings around the balance wheel area. I will let the watch run down so I can look more closely with the balance wheel stopped.
