Hello, I am new here. I recently came across two family Omega watches that I am looking to track down more information on. I heard this is the right place. Any help would be greatly appreciated! Here is the info I have: Watch 1 Omega: numbers on case back1660174 & 3660833. Maybe a 1973 Geneva but the name is not displayed on the face. Watch 2 Omega: numbers on case back 003612 & KM6324. Seamaster but unsure what year.
