Housed in a 42mm round stainless steel case measuring 14.35mm thick, the Superocean Heritage II UB2010121B1A1 pairs its steel construction with a stainless steel mesh bracelet secured by a fold-over clasp with safety release. The unidirectional rotating bezel is rendered in 18kt rose gold and features a black ceramic ring, lending a two-tone contrast that carries through to the dial.
The black dial presents luminous rose gold hands alongside index hour markers and minute markers around the outer rim. A date display sits at the 6 o'clock position, and the dial operates on an analog configuration. Powering the watch is the Breitling Calibre 20 automatic movement, which delivers a 70-hour power reserve and chronometer-grade timekeeping.
A scratch-resistant sapphire crystal protects the dial, while a screw-down crown and solid case back contribute to water resistance rated at 200 metres / 660 feet. The band width measures 22mm. This example is presented with its original box and papers.
