Hi. I have an oris big day/date which I bought brand new last 2019. I rarely use it except for occasionally winding it from time to time. In short, I kept it in my watch case most of its life with very infrequent wrist time. Anyway, I used it this week and I noticed that it stopped after 2 days of wearing it more than 12 hours per day. I tried to shake a little bit to make it start but stops after a few seconds. When I tried shaking it for 1 minute, I noticed a clanking sound inside which I never heard since new. When I opened the back since It's out of warranty I noticed the rotor was loose and when I tried to screw it in I can't lock it. Can I do this on my own or bring it to oris? Any suggestions appreciated.

Hello! My first question / project as a new member: I have a watch with a Ronda 4438, or perhaps 4439 automatic movement. The rotor has considerable play due to wear. I have been unsuccessful at finding information about the proper rotor removal method. Referring to the attached photo - I have identified the two stake marks at the rotor hub, but I do not see any retaining components or clips (perhaps the component that I marked with arrow?). Any guidance would be much appreciated! Cheers, Neil

I just purchased a Waltham Selfwinding watch marked B-251K on the inside of the case back. First of all, it is marked 25 Jewel on the face and 17 Jewel on the rotor, which I found odd but its nothing I haven't seen before, and that's where the trouble started. The watch runs, and runs very well. However, the rotor is wobbly and loose that it contacts the balance wheel at times in its travel. The rotor does not attach with a screw, but rather with a sort of sliding clip. I am no watch repairman, more of a tinkerer who has opened and successfully repaired and maintained a watch or two in my life. I'm beginning to think this might be the wrong rotor, but it appears to be a perfect match, even drops in perfectly, but it is so loose it practically falls out. Ideas anyone?
