About the Superocean Heritage family
The Superocean Heritage was introduced in 2007, inspired by the original Superocean of 1957. It has a cleaner, more classic look than the modern divers, with a polished bezel and, on many models, a fine mesh bracelet.
The catalog includes automatics and chronographs with calibers such as Breitling 10, 13 and 17 and the in-house B01, in steel, red gold and steel and red gold. Later models include the 57-inspired editions. Dealers identify the size and dial and check that the mesh bracelet is complete.
