Yes I am sad. So far I have only serviced two mainsprings, but they ended to be worse than before.
I open the barrel of my Seiko 70xx watch, take the spring out carefully and then I use a piece of paper sinked on naphtha to clean the old oils. Then I use another piece of paper sinked on IPA to rinse the spring. And then a third piece of paper with some drops of 8200 to oil it.
I clean the barrel and arbor in the ultrasonic, also using naphtha and then IPA. Dry it properly and apply 4 drops of 8217 grease, in quarters.
Lastly I insert the spring into the barrel, manually, mount the arbor and close the barrel.
The problem is that althoug the watches run with these MS, they run only for a few hours after wearing them all day. The last watch I've serviced only runs for 4 or 5 hours, sometimes less than that, so I've replaced the barrel complete with an old one, not serviced, and now the problem is gone, so no doubt the fault is mine.
I guess the spring is slipping inside the barrel. Is 4 drops of 8217 too much? How do you oils mainsprings?
I'm not sure about that now. I will need to check it out when I go over his house. I was sure the main spring was oiled to much and it was slipping. But since you can wind it and it works fine. It has me puzzled. Maybe he replaced the main spring with a stronger strength spring.
My brother had his Raymond Weil watch cleaned at a local watch repair shop. And now it won't stay running over night. The repairman says he is not moving enough during the day. He never had this problem for the ten years he owned the watch until now. It does run all night if you manually wind it. Any thoughts on what has happened.
Hello. I have recently assembled a watch using a seagull copy of an ETA 6497. I’ve noticed if the watch sits still for a while I have to shake it to get it started again. I was wondering what might be the cause of this and how I might could resolve the issue. Thank you
My first post here...! Can anyone advise me on the best way to remove the movement from this clock please? The winder and other parts in the rear are stopping me taking the movement out. I cannot see an obvious way to remove the winder and hand adjuster. Can anyone help please?
