The Speedmaster 57 is a modern ode to Omega’s first generation of Speedmasters. It features a case with straight lugs and a bezel with the tachymeter scale engraved. The same features were found on early versions of Omega’s iconic chronograph, while later models feature the swirling ‘lyre’ lugs and a bezel with separate inlay still in use today.Reference 331.12.42.51.01.002 has the ‘broad arrow’ style hands with ‘vintage’ colored Luminova. The same material is found in its recessed hour markers.
