The Omega caliber 1120 is an automatic movement found in some Omega Seamaster Pro 300M watches from the mid 1990s (1996?). Technical documentation was found dated May 1995. This movement can be found in both the full-size 41mm and the mid-size 36mm SMP models. The 1120 is essentially based on the ETA caliber 2892-A2 framework. It has 21 jewels with a beat rate of 28,800 bph, 4Hz.

91 other watches in the library run the Omega 1120.
