Breitling Superocean A17378 46mm (2023)

The Breitling Superocean Automatic 46 A17378 is a bold and capable modern diver that blends professional-grade water performance with contemporary, sporty styling. Its large 46 mm stainless-steel case houses a deep black dial with broad luminous hands and indices for easy legibility in all lighting conditions, paired with a matching black ceramic-inlay bezel that resists wear and fading. Powered by Breitling’s reliable automatic Calibre 17 movement — a chronometer-certified workhorse with roughly 38 hours of power reserve — the watch delivers robust precision whether you’re timing dives or daily activities. Rated to 300 m water resistance and built with a spirited design, the Superocean 46 wears confidently on a black rubber strap finished with a secure folding clasp, making it comfortable for active lifestyles both in and out of the water.

The Superocean Automatic 46 revives Breitling’s heritage of large-format, high-legibility dive watches while incorporating modern materials like the ceramic bezel insert for enhanced durability. Its robust water resistance, COSC-certified movement, and bold design make it a strong choice for enthusiasts seeking a high-performance diver that stands out on the wrist.
