3135 Movement

[crhfish]

Well, I decided to take a look at my newly acquired Sub to see if it needed cleaning. I had tested the time and it ran 30 seconds slow in 48 hours and the reserve was at least 10 hours short. Opened it up and immediately new something was wrong. Long story short one of the two screws that holds the auto winding assembly had come loose and had lodged in the rotor. Before it came out all the way it had worn against the rotor for a while causing some "rub dust". Took it apart, cleaned it, oiled it with some new mobius syth that I bought just for this watch. I found a screw that actually fit very well to replace the mangled one. The rotor is worn on the underside a bit, but the movement looks like new.

This was my first time to clean one of the newer Rolex movements. I was very impressed.

I've got it back together now and I'm retesting it. So far so good.
