Omega Caliber 1120

The Omega caliber 1120 is an automatic movement found in some Omega Seamaster Pro 300M watches from the mid 1990s (1996?). This movement can be found in both the full-size 41mm and the mid-size 36mm SMP.

The 1120 is essentially based on the ETA caliber 2892-A2 framework. It has a beat rate of 28,800 4Hz, 21 jewels and a power reserve of 44 hours. This movement has a quickset date, hacking seconds, and can be hand-wound.

This movement replaced the Omega caliber 1109.
