The Speedmaster 57 is a modern tribute to Omega's earliest Speedmasters, featuring straight lugs and an engraved tachymeter bezel. These same features appeared on early iterations of the iconic chronograph, whereas later models have the swirling 'lyre' lugs and a separate-inlay bezel that remain in use. Reference 331.10.42.51.01.002 has 'broad arrow' hands with 'vintage' Luminova, matching recessed hour markers, and a stainless steel bracelet.
