Model Number vs Serial Number

• Omega 18k Yellow Gold Constellation Grand Luxe Ref. 2930 SC. SC means center seconds vs a sub-register for the seconds only. 2930 refers to the automatic Omega Constellation "Grand Luxe" with fancy lugs.

•  The model number is engraved inside or outside of the case back depending on the production year. 

• Sometimes a corresponding serial number will also be on the case back. You'll also see the metal type and case maker engraved inside the case back.

Omega Serial Number Guide

• Most swiss manufacturers use chronological serial numbers to track production and identify each watch. The serial number determines the order in which the watch was produced.

• Modern Omega will have an etched seven to eight-digit serial on the case-back or back of the lugs. Each model serial etching can differ in location.
