If you had asked for a Grand Seiko part it's no surprise that you have been told that these are not sold, as service and repair on these piece happens only by giving the piece to an official Seiko service center which in turn ships it to Japan for the work to be done.Īt the same time the Chinese produce a variety of movements which shock spring closely resemble much more expensive watches of all brands, but are not really compatible with these either. In particular, the one on bottom right is the 7R14 found on Credor watches which can cost €50,000, so very far from the ones which one can find in Rotary watches. They are either from vintage calibers, or from the high and upper Seiko segment. PPS why do you require a pic.īecause none of the mov.ts that are in your picture are sold by Seiko to third parties under the mentioned SII brand, including the top right with the eccentric regulator. PS I do not have a pic of the original movement I was working on. Can’t see any random debris which might get in the way, nada, as yet. Which is sort of what I expected as it keeps good time when it is running. Balance looks good, escape wheel and lever also looks good. All the wheels are OK, teeth and splines all fine. So all I am left with, is taking the train wheels out and examine them for damage. I was sort of expecting it to be a damaged tooth on the fourth wheel, as it always stops in the same place, but I can’t see any damage under a loupe. I took it out the case to remove any interference from the case, still the same.Īlso took off the hands to see if they were causing issues, ditto. 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.
