The Speedmaster 57 is a modern ode to Omega's first generation of Speedmasters. It features a case with straight lugs and a bezel with the tachymeter scale engraved. The same features were found on early versions of Omega's iconic chronograph, while later models feature the swirling 'lyre' lugs and a bezel with separate inlay still in use today.

As reference 331., both case and bracelet are done in yellow gold.
