Here are some images of a 1920s Rolex I just acquired. Thought I would share them here in case they are of interest, and also to ask some advice. There is some rust damage to the movement which I hope you can make out in the photos. Does it look like the movement can be cleaned and restored to working order? As far as I can see it looks like the rust is confined to the surface. I don't want to spend more on servicing the movement than the watch itself is worth.
Appreciate any thoughts.
