My Seamaster, Constellation or DeVille has the older 1109 movement. Is that bad?

Earlier versions of the Seamaster Pro used the OMEGA 1109 automatic movement. This movement was also used in a number of other OMEGA models, including the Seamaster 120, Constellation, and De Ville. A small portion of these watches may have trouble with a winding gear that prevents the watch from reaching its stated 44 hour power reserve. Around 1996, OMEGA revised the movement slightly to fix this potential winding problem and to add rhodium finishing on some parts for extra durability. The revised version is called the OMEGA 1120.

There is no cause for alarm simply because your watch has the 1109 movement. Most of them are perfectly fine. If you are experiencing winding problems on a 1109-based OMEGA watch, an OMEGA service center may be able to resolve the issue.
