Founded in 1848 by Louis Brandt, Omega is one of the world's best-known and most respected watch brands. Based in Switzerland, the company produces stylish and beautiful timepieces for men and women. Whether your Omega watch is a family heirloom passed from generation to generation or a special gift from years ago, you can date it by referring to its serial number. The company offers an official document called an "Extract of the Archives," but as of April 2011, this service was not available to U.S. customers. Thankfully, independent watch retailers provide lists of serial numbers to help you date your watch.

Place the watch face down on a clean, soft cloth on top of a hard surface such as a table or desk.

Examine the back of the watch for the timepiece's unique serial number that may be engraved in the metal.

Use a small screwdriver to open the watch case if you don't see the serial number on it. Place the tiny screws to one side.

Remove the back of the case and locate the serial number on the watch movement. Write down the number and put the watch case back together using the screwdriver.

Navigate your Internet browser to a website that lists serial numbers for all Omega watches made since 1895. Cross-reference your serial number with the ones listed to obtain an approximate date for the watch's production.
