A friend's girlfriend has asked me to help her sell her vintage Rolex. It's quite nice, 9K, guilloché face in good shape and pretty hands.
Looking at Ranfft, I feel that this is a Rolex cal 600 (Alpina 819, Gruen 819); however, there's no sub seconds, bridges are a bit different (and I don't fancy taking the dial off…). In your collective wisdom, is this likely to be correct? With the shock device shown, ca 1930?
The Poincons de Maitre number within (as shown) is clearly marked as 136; however, my list doesn't show a maker for this symbol and number (if it were just the hammer head alone, it would be 136 C.R. Spillmann SA). So although it's the hammer with the handle instead, is it still a Spillman case?
Any other thoughts on it? (Needs a service, as you can see!)
