About the Omega 3603
The 1285 is the thin column-wheel chronograph the Piguet piece traces, and the 3603 adds a 24-hour hand to it, with 37 jewels, a 55-hour reserve and a beat of 28,800 vph, certified by the COSC. Every reference here is 44 mm or 44.25 mm, the size the extra module asked for.
In the library it powers 6 Aqua Terra Chronograph GMTs, 4 Speedmaster Broad Arrow GMTs at 44.25 mm, 3 De Ville Chronoscope GMTs, 3 Speedmasters and 2 Seamaster Diver 300M GMT chronographs.
The 3313 is the co-axial version of the same base without the GMT, and the 3612 the split-seconds version; the glossary defines the GMT display.
