Hi everyone. Some vintage oris stop running not long after cleaned, I am sure the problem is common with vintage oris 677 kif and 704 kif.since I got many of them. I think of worn down staffs or weak main spring as the cause.
Interestingly dropping one drop of aircraft fuel on top of the upper and lower jewels of balance wheel only and it fly like combat jet.
Lots of hope to recieve your opinion.
Yesterday my Oris watch hit a tiled floor when the strap pin broke and the back crystal popped off. Being in a rush , I quickly pressed it back into position and left it for later investigation.
Today the crystal seems to be fixed in position, but I have no experience of removing or replacing these. Was a simple press of the thumb strong enough to do the job? How can I check, other then testing with my thumb nail. Are these a simple pop on fixing?
I’m struggling to understand what is a left winding mainspring and a right winding mainspring. Just to clarify, can anyone tell me what is the orientation on this one in the image and what the other one would look like?
Well, I don't know the official terms because I'm only an amateur. What I meant saying "full wind" on the 1575 (which is of course an automatic) is: I turned the crown about 40 revolutions so that I'm absolutely sure the mainspring is in the "slipping area". Thats "full wind of an automatic" for me.
Status update: After 30 hours the watch is 11 seconds ahead of the atomic clock. So the "about +9 result" of the timegrapher seems to make sense. I will observe until sunday evening if this is continuing.
