Breitling Superocean Heritage B31 Automatic 40

Breitling's Superocean Heritage B31 Automatic 40, reference AB3110361L1S1, is a dive watch with a 40 mm stainless steel case. The case measures 11.73 mm thick, and the sapphire crystal sits above a green dial with a date aperture at six o'clock. A unidirectional ceramic bezel surrounds the dial, and the screw-locked crown carries two gaskets for added security. Inside is the Breitling B31, a self-winding manufacture calibre with a power reserve of approximately 78 hours, certified as a chronometer. The sapphire display back shows the movement through the case. Luminous hands and indices keep the dial legible in low light. A green rubber strap closes with a steel folding clasp, and the case is rated to 200 metres of water resistance.
