The Superocean A17391 isn’t just a sport watch; it is a specialized tool. The 44mm stainless steel case is fitted with a thick, cambered sapphire crystal with anti-reflective treatment on both sides. To handle the crushing pressures of the deep, the watch is equipped with a helium escape valve at the 10 o’clock position, a feature reserved for the most elite diving watches. The screw-locked crown with two gaskets ensures that even at 2,000 meters, the internal mechanics remain perfectly dry.
The black dial features oversized Arabic numerals and chunky hands, all heavily coated with Super-LumiNova® for maximum visibility in the “midnight zone” of the ocean. This reference is often sought after for its “Abyss” color accents—available in white, blue, yellow, red, or orange—which add a splash of personality to the seconds hand and inner bezel ring. The unidirectional rotating bezel features a 60-minute scale, allowing divers to track elapsed time with total security.
At the heart of the Ref. A17391 is the Breitling Calibre 17. This self-winding mechanical movement is a certified Swiss Chronometer (COSC), ensuring it maintains a daily variation of no more than -4/+6 seconds. Whether mounted on the professional-grade Diver Pro rubber strap or the high-polish Professional II stainless steel bracelet, the Superocean 44 offers a commanding presence and legendary durability. For the collector who wants a watch that is as tough as it looks, the A17391 remains a definitive choice in the luxury diver category.
