Description
The Breitling Superocean 46 Blacksteel Ref. M17368B71B1S2 is a commanding professional diving watch that combines Breitling’s renowned maritime heritage with a bold, contemporary design. Engineered for demanding underwater conditions, this substantial timepiece embodies the technical performance, durability and unmistakable sporting character associated with the Superocean collection.
Presented in an imposing 46mm stainless-steel case with a black DLC coating, the Superocean Blacksteel delivers a distinctive stealth-inspired appearance. Its combination of substantial proportions, matt black surfaces and robust construction creates a powerful wrist presence while reinforcing its identity as a serious professional diving instrument.
The black dial features oversized luminous hour markers and broad hands designed to provide exceptional legibility in low-light and underwater conditions. Contrasting white markings create excellent visibility against the dark background, while the discreet date aperture at 3 o’clock adds practical everyday functionality without compromising the purposeful dial layout.
Surrounding the dial is a substantial unidirectional rotating diving bezel with a clearly defined 60-minute scale. The bezel incorporates a ratcheted locking mechanism, allowing the wearer to secure the selected diving-time position and helping prevent accidental adjustment during underwater activities.
Powering the watch is the Breitling Calibre 17, a COSC-certified self-winding mechanical movement operating at 28,800 vibrations per hour. Based on a proven Swiss automatic movement architecture, the calibre provides approximately 38 hours of power reserve and delivers the accuracy and reliability expected from a professional Breitling sports watch.
One of the defining characteristics of this reference is its exceptional water resistance of 2,000 metres. The substantial case construction, screw-locked crown and helium escape valve are engineered to withstand the extreme pressures associated with professional deep-sea and saturation diving.
The dial is protected by a cambered sapphire crystal with anti-reflective treatment on both sides, ensuring excellent clarity and resistance to everyday wear.
This particular reference is fitted to a black rubber strap, complementing the Blacksteel case and creating a cohesive monochromatic appearance. The strap provides excellent flexibility and comfort while reinforcing the watch’s sporting character and suitability for water-based activities.
The Breitling Superocean 46 Blacksteel Ref. M17368B71B1S2 represents an impressive combination of professional diving capability and contemporary Swiss luxury watchmaking.
