Small differences in the recent Seamasters posted presents the need for details. This model has the reference number 166.002, differing from 166.001 having white gold details on the dial as opposed to the other model´s yellow gold dial indexes, Omega logo and hands. As before, this watch has been fully serviced (Sep 2020) and comes with 12 months warranty. It is a very nice example, but you should know a couple of things about it: The dial has been fixed with (very small) screws at 2 and 8, and an original Omega crystal was unobtainable. The diameter is 34,5mm and the serial number 22213xxx dates it to ca 1965.
