How big is the Omega Speedmaster 331.10.42.51.01.002?

The case measures 41.5mm across. Case material: Steel. Case size alone is a poor guide to how a watch wears; lug-to-lug length and how the bracelet drops off the case matter more, which is why we suggest trying one on before you commit.

Caliber 9300. Power reserve is 60 hours. It beats at 28,800 vph. The movement uses 54 jewels.

When was the Omega Speedmaster 331.10.42.51.01.002 made?

Omega produced this reference from 2013 to 2019. Production years matter when you are valuing one, because dial, bezel and bracelet details often changed inside a single reference run.

Does the 331.10.42.51.01.002 have a nickname?

Speedmaster '57 Co-Axial. Collector nicknames are not official Omega names, but they are what people actually search for and what they are called across a showroom.
