Housed in a round stainless steel case measuring 42mm, the Superocean Heritage B01 Chronograph reference AB0156161C1A1 features a uni-directional rotating bezel with a black ceramic top ring. A screw-locked crown and transparent case back round out the case architecture, while a scratch-resistant sapphire crystal protects the deep blue dial beneath. Water resistance reaches 200 meters / 660 feet.
The blue dial is appointed with luminous silver-tone arrow-shaped hands and index hour markers, with minute markers tracking the outer rim. Three silver sub-dials display 60-second, 30-minute, and 12-hour chronograph readings, and a date window appears between the 4 and 5 o'clock positions. The watch rides on a stainless steel mesh bracelet secured by a fold-over clasp with safety release.
Powering the watch is 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. Functions include chronograph, column wheel, date, hour, minute, second, and chronometer. This example is accompanied by its original box and papers.
