Measuring 46 mm in diameter and 13.2 mm thick, the stainless steel case features a screw-locked crown with two gaskets and a bidirectional ratcheted bezel, delivering serious water resistance to 300 m (1,000 ft). A cambered sapphire crystal with glareproof treatment on both sides keeps the vivid blue dial clearly legible in any light.
Power comes from the Breitling 17 self-winding movement, offering approximately 38 hours of power reserve. The watch is presented on a blue rubber strap secured by a folding buckle, completing the sport-ready aesthetic of reference A17378E71C1S1.
