8f56 Help with Seiko Perpetual 8f56 movement.
jbirkrepair posted a topic in Watch Repairs Help & Advice
Hi, I recently purchased a Seiko GMT Perpetual off eBay. The watch has a 8f56 Movement which is the high accuracy quartz movement. The watch was purchased with a low battery (indicated by the second hand ticking every 5 seconds). I've since replaced the battery and reset the perpetual calendar, the watch was working for about 3 hours and then just stopped. I've since tried to reset the perpetual calendar again and it doesn't do anything just completely dead. I recently went to a local watch repair shop and they said it would need a entirely new movement and would set me back £250 for it. It would however be done by Seiko not themselves. Any help is much appreciated.

Tissot T063.637.16.057 (ETA G15.561): It is possible to calibrate the date change moment? I've tested 3 watches, and they all had problem with date change moment: 1) 22:40, 2) 23:47, 3) 23:54. But other users report that they have date change exactly at 00:00, so may be it is possible to calibrate the moment when the date is changed?
