Built around a round 46mm stainless steel case, the Superocean A17378211B1S1 is engineered for serious underwater use with a water resistance rating of 300 meters. A bi-directional rotating bezel pairs with a cambered sapphire crystal, while the black dial features luminescent index hour markers and luminescent hands for reliable reading in low-visibility conditions.
Power comes from a self-winding mechanical movement, keeping the watch running without the need for manual winding during regular wear. The black rubber strap with folding clasp secures the watch comfortably on the wrist, and an analog display rounds out the functional, sport-oriented layout.
This example is unworn and comes complete with its original box and papers, dated to 2024. It represents the Superocean line's long-standing position as a capable and well-appointed diving instrument from Breitling.
