The Speedmaster 57 is a modern homage to Omega's earliest Speedmasters, with straight lugs and an engraved tachymeter bezel. These same features appeared on early versions of the iconic chronograph, while later models have the swirling 'lyre' lugs and a separate-inlay bezel still used today. Ref. 331.20.42.51.01.002 has a case and bracelet combining stainless steel and red gold, with a black dial.
