Re: Movement Question 1109 vs. 1120

Take a look at http://www.dziglar.com/zowie/faq/seamaster.shtml#problems. You'll see that "earlier versions of the Seamaster Pro used the Omega 1109 automatic movement. This movement may have trouble with a winding gear that prevents the watch from reaching its stated 44 hour power reserve. Omega now uses the Omega 1120 movement, which is essentially the same as the 1109 except for a few revisions to fix this potential winding problem and to add rhodium finishing on some parts for extra durability. If you are experiencing winding problems on a 1109-based Seamaster, an Omega service center may be able to resolve the issue."
