An Overview of the Omega Wristwatch reference codes.


I first saw the data presented here in a posting, by Shaun Thornton, on the Time Zone Omega Forum.
"Shauns" values differ somewhat from those presented by Chuck Maddox on his Omega Case Reference codes webpage. I took a copy of the posting & filed it in the "I wonder why they're different" part of my brain.
Recently (end of 2002) I got hold of an Omega "Dressing Components Catalogue" via eBay. This catalogue is dated 1993 & contains the overview shown here ( The data is the same as that posted by Shaun).
The catalogue DOES NOT state from (or until) when these codes are valid.



1st Digit
2nd Digit
3rd Digit
1 - Gent's Watch 1 - Manual winding without second 1 - Non-water-resistant
2 - Gent's Jewellery Watch 2 - Manual winding small second 2 - Non-water-resistant Calender
3 - Gent's Bracelet Watch 3 - Manual winding centre second 3 - Non-water-resistant chronometer
4 - Gent's Jewellery Bracelet Watch 4 - Manual winding chronograph 4 - Non-water-resistant chronometer calender
5 - Lady's Watch 5 - Self-winding without second 5 - Water-resistant
6 - Lady's Jewellery Watch 6 - Self-winding centre second 6 - Water-resistant Calender
7 - Lady's Bracelet Watch 7 - Self-winding chronograph 7 - Water-resistant chronometer
8 - Lady's Jewellery Bracelet Watch 8 - Electronic chronograph 8 - Water-resistant chronometer calender
9 - Electronic



Wow ! Very interesting but what does it mean ?

The Case reference number of Omega watches is stamped ( NOT engraved!) on the inside of the rear cover.
To see it you'll need to either remove the rear cover, or in some cases, remove the crystal & then the movement.
Some examples are :- The 3 or 4 digit number at the end, is simply a unique identifier for the watch. There is no coding "behind" this number. It is simply the next watch gets the next unused number. Omega started with 3 digit numbers & at some stage moved to 4 digit.

This code is NOT the PIC ( Product Identity Code ) number used in current Omega Catalogues, or on the warranty cards. An example of a PIC code is something like 3813.50.00
PIC codes are covered by Chuck Maddox on his PIC Codes webpage
