The Superocean A17377211O1S1, seen from the bench

The Breitling Superocean 36 A17377211O1S1 belongs to a line tracing its roots to 1957, when Breitling launched the first Superocean for marine professionals. The contemporary version in steel and ceramic features a 36mm case combining stainless steel with a ceramic insert for scratch resistance and lasting colour stability. The movement is the Breitling Caliber 17 ND mechanical calibre, certified COSC with precision of ±4/−6 seconds per day. Water resistance reaches 300 metres, ensured by a screw-down caseback and crown plus anti-reflective sapphire crystal. The lug width is 18mm, a proportioned dimension for the 36mm case requiring a calibrated strap construction.

Frequently asked questions

What is the lug width of the Breitling Superocean A17377211O1S1?

The Breitling Superocean A17377211O1S1 has a lug width of 18mm. This is the measurement to use when selecting compatible replacement straps, whether in leather, rubber or NATO configuration.

What is the best strap for the Breitling Superocean A17377211O1S1?

It depends on intended use. For formal settings, an 18mm vegetable-tanned alligator strap offers the best balance of refinement and durability. For sports or marine use, an FKM rubber strap or a water-resistant nylon NATO is more functional. Smooth calf leather is the most versatile option for everyday mixed use.

How do you change the strap on the Breitling Superocean A17377211O1S1?

A springbar tool or a fine-tipped lever is sufficient to remove the spring bars securing the strap to the lugs. The operation does not require technical expertise, though it is advisable to consult a watchmaker to avoid scratching the case or the ceramic bezel.

Are there aftermarket straps compatible with the Breitling Superocean A17377211O1S1?

Yes. Any strap with an 18mm lug width is technically compatible. milanostraps.it offers a curated selection of handcrafted 18mm straps suited to this model, available in alligator, calf leather, rubber and NATO, fitted with standard 1.5mm spring bars.

How long does a leather strap last on a dive watch like the Superocean?

A leather strap on a dive watch has an average lifespan of 12 to 24 months under regular use, reduced to 6 to 12 months with frequent exposure to water and perspiration. To maximise longevity, dry the strap after each contact with water, avoid prolonged direct sunlight, and apply a leather conditioner periodically. Vegetable-tanned leather tends to develop a pleasing patina with use but requires more maintenance than rubber.
