·Mine has on the caseback inside 1702 number. May it be the ref?
This model was produced during a period when Omega changed its marking system. At the beginning of the production, cases and calibers beared each a serial number (one individual for each case and another individual one for the caliber).
Later, wristwatches cases beared an additionnal 2 or three number to pair the different case parts. Sometimes this ‘pairing’ number was the last digits of the case individual number, sometimes not.
Then, in the late 40’s early 50’s Omega stamped casebacks with only the model reference number, casebacks didn’t have individual or pairing numbers anymore. Caliber still had an individual serial number.
The easy rule to remember is that if a watch has a serial number (7 or 8 digit) on the caseback, any additional 2 or three number on the case and caseback is a pairing number. If it doesn’t have a serial number on its caseback,but only a 3 or 4 number one (sometimes with two additional ones : XXXX-XX, it s the reference number.
The serial on your watch is outside the caseback and the pairing inside it and on the lug.
