The Speedmaster 57 is a modern homage to Omega's earliest Speedmasters, with straight lugs and a bezel engraved with the tachymeter scale. These characteristics were seen on early versions of the iconic chronograph, whereas later models adopted the swirling 'lyre' lugs and a separate-inlay bezel that remains in use. Ref. 331.12.42.51.02.002 has a stainless steel case, calf leather strap, and a silver dial.
