Transocean Chronograph Limited Edition was the first B01-powered Breitling to feature a see-through caseback. It has a black dial with silver subdials.The Transocean Chronograph reinterprets the pure design of the classic 1950s and 60s chronographs in a resolutely contemporary style. The slender, understated fuselage carries onboard a high-performance “engine” in the shape of Caliber 01, entirely developed and produced in the Breitling workshops. The dial is a model of clarity and readability featuring refined details such as applied hour-markers, finely recessed and snailed counters, as well as an 18K gold version of the B initial that served for many years as the brand symbol.
