About the Omega 1120

The 2892 is the thin automatic base most Swiss maisons built on, and the 2892 piece explains why. Omega's version runs at 28,800 vph with a 42-hour reserve and 23 jewels, at 25.6 mm across and 3.6 mm high, and it is the movement of the Seamaster Professional 300M from 1993 until the Co-Axial 2500 took over in 2005, including the blue-dial 2531.80 that succeeded the quartz Bond watch in the films.

In the library it powers 54 Seamaster Diver 300M references, the 41 mm and the 36.25 mm mid-size, 17 De Ville Prestige automatics, 14 Constellations and 7 Seamaster 120Ms. Cases run from 22.5 mm to 41 mm, with 41 mm the most common at 35 references.

The 1109 is the non-chronometer version of the same base, and the 1538 the quartz movement the Seamaster offered beside it.
