Enter the movement/caliber number from your Omega watch to find out when Omega started to manufacture that movement and therefore the approximate earliest date for the watch itself. It is not 100% accurate and may be a year or two out. This can be used in conjunction with the Omega serial number decoder and the Omega model decoder to confirm the age of the watch. This movement database currently contains over 400 Omega movements from 1928 to 2016 and is growing daily. It currently supports movements numbered from 095 upwards.
