About the Omega 3330

ETA developed the A08 as a column-wheel chronograph on the 7750's footprint, and Omega's version adds the co-axial escapement and the Si14 silicon balance spring, with 31 jewels, a 52-hour reserve and a beat of 28,800 vph, at 30 mm across and 7.9 mm high. It is COSC-certified. It sits below the in-house 9300 in the range and above the older 7750-based chronographs.

In the library it sits under 48 Speedmaster references, the Speedmaster Racing 40 of 2012, the Speedmaster 38 of 2017 and the Mark II reissue of 2014, and 7 Seamaster Diver 300M chronographs at 44 mm, including the Regatta. The 38 mm case accounts for 30 references and the 40 mm for 14.

The Valjoux 7750 piece explains the layout the A08 was designed to match, and the 9900 is the Master Chronometer chronograph above it.
