Breitling Superocean Heritage AB2010 42 mm

The Superocean Heritage B20 Automatic 42 AB2010 keeps the familiar 42 mm stainless-steel profile while sharpening its modern diving equipment. Its cambered double-glareproofed sapphire crystal, screw-locked crown, screwed caseback and ratcheted unidirectional bezel support 200 metres of water resistance. Super-LumiNova and stick-and-dot indexes preserve the collection's clarity, giving the watch a marine character that feels composed rather than overbuilt.

Inside, Manufacture Calibre B20 is an automatic 4 Hz movement with a bidirectional rotor, 26 jewels and a 70-hour reserve. Its base is Tudor's MT5612 architecture, reflected in the calibre's Breitling/Tudor alliance, and the date remains its only calendar complication. Hacking seconds allow exact setting, while the long reserve gives the straightforward three-hand format a more substantial mechanical foundation.
