The Speedmaster 57 is a modern tribute to Omega's first-generation Speedmasters, featuring straight lugs and a bezel with the tachymeter scale engraved. These characteristics were seen on early versions of the iconic chronograph, while later models feature the swirling 'lyre' lugs and a separate-inlay bezel that remains in use. Reference 331.90.42.51.04.001 has a titanium case and matching bracelet, with a white dial and bold blue accents.
