I tried all other positions and it was OK. Sweep seconds hand Always in the same place. Probably as good as any other cheap auto anyway.Īs to stopping, I left it overnight last night for around 12 hours and it kept time as well as the timegrapher indicated, but within 30 seconds it would stop when placed winder down. But it is a fairly ordinary movement so I don’t expect it will hold it that well.
I timed it dial up and dial down to make sure the balance was reasonably mounted and I could easily get the beat error to around 0.5 - 0.7 and a rate of around 9 secs per day. The balance amplitude was observed on a timegrapher. I guess I am going to have to scour movement pics to see what I can turn up. I have now taken off the automatic winding plate for a good look see so far, and there is not one distinguishing mark anywhere. Still very much an amateur when it comes to watches, so any hints and tips welcome. The balance amplitude is also a very low at around 170-180 (I can't see the hands blocking each other, or anything on the dial to stop it. Funnily enough it does not seem to stop when left dial up and not worn. The watch intermittently stops when worn, but the sweep seconds hand is nearly always in the same position when it stops (pointing at about 20 past) so I am suspecting some damage or misalignment in the works. I would appreciate a hint on which movement it is please. the day (at 9) and date (at 3) seem only to be set by the two pushers. The movement seems odd initially as whilst it has three sundials, only the 24 hour hand at 6 0'clock seems to be synchronised with the movement. The Rotary Case ID for the watch is GS02375/01. I am guessing it is some sort of Chinese skeletonised movement, but there are no marks visible on the movement. I am looking at a Rotary Watch, pretty identical to the one on the photo.
