Rotor moves when winding auto watch manually...?
Hey all,
Quick question for the tech experts. My friend has a Tudor black bay that functions perfectly in every way except one thing that I find odd. When we wind the watch manually with the crown it feels like the rotor inside the case spins. It is correlated with the crown such that the faster you wind the crown the faster the rotor moves... What could this be? Something wrong I suspect. Please let me know thoughts! Thanks! Best, Greg

A lack of lubrication is the most the most likely reason. It's not uncommon.

Thanks Vanessa! I was worried it was Something worse. Is that odd for a watch as new as the Tudor black bay (only. Year or so old)??

Yes and no. It depends what the watch has endured during that first year. Heavy impact on the watch could have moved the lubricating from its original intended location. Impact includes playing tennis, golf, riding a Harley, etc.

I have heard that's a common problem with the reversing wheel on an ETA 2824. A watch smith should easily be able to clean and re oil that part. Or just replace it and oil it. They are cheap enough.

Also the problem with eta auto devices is that too much oil locks them up as well and is most likely the issue. When oiling this device I use naptha benzene with a drop of mobious hp 1000 drop it in after cleaning then blow dry it off. I learned this little tibit from Remy Welshly from ETA sorry if I spelled your name wrong. Rikki

May I ask why to use such high viscosity oil as hp1000 inside reversers? For example ETA 2824 recommends 9010 which is very thin.
That makes sense to me as reverser clicks don't deal with high torque while "reversing". Are there any other points that I don't see? |
