Housed in a 42mm round stainless steel case with a solid case back and screw-down crown, this Superocean Heritage B31 is built for serious water performance, rated to 200 meters / 660 feet. A uni-directional rotating black stainless steel bezel frames the green dial, which features silver-tone luminescent hands and index hour markers arranged around a minute-marker track at the outer rim. A date window sits at the 6 o'clock position, and the scratch-resistant sapphire crystal protects the analog display.
Power comes from the Breitling Calibre 20, an automatic movement based on the Tudor MT5612. It contains 28 jewels, beats at 28,800 vph, and delivers a power reserve of approximately 70 hours — a dependable engine beneath the Heritage's classic diving aesthetic. The watch is completed by a stainless steel bracelet secured with a fold-over clasp.
This example is Swiss made and comes presented with its original box and papers, reference AB3111361L1A1.
