I just realized Bob's Watches isn't necessarily the only serial number reference out there; that is to say, other websites (i.e.,
this one) yield different results.
I have an older Datejust listed for sale elsewhere, and after looking up its 5.8million serial number on Bob's Watches, someone asked if I was sure it's from 1979 and not 1980 (prob for birth year reasons). Naturally I searched for different sources and realized the discrepancies.
May I ask where the knowledgeable folk on this fine forum go to find reliable serial number years?
Thanks in advance!
