About the Omega 3303

The 1285 is the 1185 architecture, a column wheel and a vertical clutch in a thin movement, enlarged for Omega; the Piguet piece traces it. The 3303 runs at 28,800 vph with a 55-hour reserve and 33 jewels at 27 mm across, and it is a COSC chronometer. The 3313 added the co-axial escapement and became the standard; the 3301 is the same movement with plainer decoration.

In the library it powers 17 Speedmaster Broad Arrow references at 42 mm and 6 Seamaster Diver 300M chronographs at 41.5 mm.

The 3603 and 3612 are the GMT and split-seconds versions of the same family.
