The Speedmaster 57 is a modern homage to Omega's earliest Speedmasters, with a case featuring straight lugs and a bezel engraved with the tachymeter scale. These features were present on early versions of the iconic chronograph, whereas later models adopted the swirling 'lyre' lugs and a separate inlay bezel still used today. Reference 331.92.42.51.04.001 has a titanium case, a white dial with blue indexes and hands, and a brown calf leather strap.
