The Breitling Superocean Heritage '57 was introduced in 2020 as a modern take on the original 1957 Breitling Superocean. Cues from its source of inspiration include the unusual hour markers and the inclined bezel - though the latter is now done in ceramic. Its case measures 42mm across, holding a caliber B10 movement. Water resistance is set at 100 meters. The Superocean heritage '57 is available in a number of variations. Reference A103701A1B1X2 is a limited edition of 250 pieces exclusive to Breitling Boutiques. It features a black dial with rainbow markers inspired by the bright colors of the hippie-era.
