Housed in a 44mm round stainless steel case, the Superocean Héritage II B01 Chronograph features a uni-directional rotating bezel with a black ceramic top ring and a screw-locked crown. The transparent case back reveals the movement within, while the case measures 15.50mm in thickness. Water resistance is rated to 200 meters / 660 feet.
The black dial is fitted with luminous silver-tone arrow-shaped hands and index hour markers, with minute markers running along the outer rim. A date display sits between the 4 and 5 o'clock positions, and three silver sub-dials track 60 seconds, 30 minutes, and 12 hours of elapsed chronograph time. A scratch-resistant sapphire crystal protects the dial.
Power comes from the Breitling Calibre 01 automatic movement, comprising 346 parts and 47 jewels, beating at 28,800 vph with a power reserve of approximately 70 hours. The watch is worn on a stainless steel mesh bracelet secured by a fold-over clasp with a safety release, and it arrives accompanied by its original box and papers. Reference AB0162121B1A1.
