My coworker wore this into work today. It belonged to his father (really, no uncles are involved). He mentioned that it was serviced a few years ago and the crystal was replaced at that time, but it hasn't been worn very much. It looks to be in fantastic original condition, although the replacement crystal has a date magnifier which I don't think I've ever seen on a Seamaster. Pardon the phone photos. He'd love to get some more info about the watch. Reference, approximate production date range (his estimate is "some time in the 60's), and so forth. Also, the original bracelet has been lost; does anyone know the reference number for it?
