The Speedmaster 57 is a modern homage to Omega's earliest Speedmasters, with a case featuring straight lugs and an engraved tachymeter bezel. These characteristics were found on early versions of the iconic chronograph, while later models feature the swirling 'lyre' lugs and a separate-inlay bezel that remain in use today. As reference 331.50.42.51.02.001, both case and bracelet are done in yellow gold.
