I recently acquired a vintage Seamaster Chronograph 176.007. It’s currently being serviced by my watchmaker and he sent this photo of the back of the dial: Whenever I’ve seen photos of the backs of dials here they have tended to be sterile, but I thought it was cool that it had a date stamp! I was curious as to whether this was common in vintage Omegas of the time, and whether any other 176.007 owners have compared this date stamp with an extract from the archives? I guess that the date stamp here would only refer to this component, but it would be interesting to know others’ experiences! I’ll share photos of the watch when it’s back with me - it’s an incoming I’m really looking forward to as I have been chasing a calibre 1040 for a while.
