I am a newbie. I am administrating an estate for a relative and I have found a pre-daytona rolex. I had it serviced and the service shop said it was real and that it was valuable. I have been trying to figure out exactly what it may be worth. I don't have pictures now as it is with a jeweler who is appraising it, but to be honest I am not sure vintage Rolexes are his speciality. It has been serviced, but shows wear. The paperwork indicates it is a 6240. It is SS with a black bezel, silver dial, and black sub dials. The band is SS links, but it has a lot of droop to it - it is pretty stretched. The dial indicates "Rolex Cosmograph"
My concern is that it has the old style non-screw down buttons - and my research indicates the 6240 was the first model with scew downs. Could it be some where made without?
