The Breitling Superocean Automatic 46 Black Steel is a family of 46 mm dive watches, not a single universal configuration. For the cited black-rubber model, reference M17368B71B1S1, Breitling lists a DLC-coated stainless-steel case, 2,000 m water resistance and an approximately 38-hour power reserve. Those are manufacturer specifications, not independently tested results; identify the reference when comparing variants or prices.

The automatic Breitling 17 mechanical movement is listed with 25 jewels, a frequency of 28,800 vibrations per hour and an approximately 38-hour power reserve. These figures describe the manufacturer’s specifications; they do not establish real-world accuracy or performance in diving conditions.
The cited configuration has a black rubber strap, 24 mm lug width and 24/20 mm strap dimensions. Breitling’s product story describes the broader model as using color-matched rubber straps with either a DLC-coated pin buckle or folding clasp, but clasp and strap details should be checked against the particular reference.

How Black Steel differs from the other Superocean 46 listings
Similar names conceal meaningful differences. In the specific official listings below, the Black Steel is thicker and has a higher stated water-resistance rating than the standard Automatic 46, while the Super Diver uses titanium and sits between them in thickness and rating. These are reference-to-reference comparisons, not claims about every configuration sold under each model name.
| Official listing and reference | Case material | Water resistance | Diameter / thickness | Power reserve |
|---|---|---|---|---|
| Black Steel M17368B71B1S1 | DLC-coated stainless steel | 2,000 m | 46 mm / 16.85 mm | Approximately 38 hours |

Price and availability depend on the reference and region
Breitling’s US listing for reference M173681A1L1S1 gives a price of USD 7,000 excluding sales tax and describes that green-rubber-strap edition as limited to 200 pieces and available only in the United States. These details apply to that reference and US listing, not to the black-strap M17368B71B1S1 or the Black Steel family as a whole. The listing was accessed on 2026-10-08; it does not establish live inventory or a current price beyond that page snapshot. Breitling’s US listing for M173681A1L1S1
What strap dimensions are listed, and what do they establish?
For M17368B71B1S1, Breitling specifies 24 mm between the lugs and strap dimensions of 24/20 mm, meaning the strap tapers from 24 mm at the lugs to 20 mm at the other end. This makes “24 mm to 20 mm tapered rubber strap” a useful starting point when searching for a replacement, but width alone does not prove fit. Before buying an aftermarket strap, confirm compatibility with the exact reference, attachment geometry, spring bars and clasp arrangement. No specific third-party strap fit or current stock is established here.

What the specifications can—and cannot—tell you
The 46 mm diameter and 16.85 mm thickness give the cited Black Steel a substantial case profile on paper. Manufacturer dimensions cannot predict how it will feel on a particular wrist, and the listed water-resistance rating does not amount to an independent test of diving performance. No hands-on assessment or independent evidence establishes comfort, timekeeping accuracy or comparative durability for these references.
For a meaningful comparison, begin with the complete reference number, then check the case finish and material, thickness, stated water resistance, movement and reserve, dial and strap configuration, and the regional listing for price and availability.
