Frequently asked questions

What is the lug width of the Breitling Superocean A173763A1C1S1?

The Breitling Superocean A173763A1C1S1 has a lug width of 22mm. This measurement should be taken with a calliper across the internal gap between the two lugs, flush against the case. Only a 22mm strap ensures correct fitment without lateral play.

What is the best strap for the Breitling Superocean A173763A1C1S1?

It depends on use. For aquatic environments, vulcanised rubber is the most coherent choice given the Superocean's diver vocation. For daily wear, a vegetable-tanned calf leather in smooth grain develops a personal patina over time. For a more formal register, an alligator strap with a deployant clasp creates a compelling sartorial contrast with the tool-watch character of the case.

How do you change the strap on a Breitling Superocean A173763A1C1S1?

The strap is replaced via the spring bars connecting it to the case lugs. Using a springbar tool, compress the bar and slide the strap free. The operation takes approximately two minutes and requires no specialist watchmaking tools, though care should be taken to avoid scratching the ceramic case.

Are there aftermarket straps compatible with the Breitling Superocean A173763A1C1S1?

Yes. Any strap with a 22mm attachment is technically compatible with the Breitling Superocean A173763A1C1S1. Milano Straps offers a curated selection of handcrafted 22mm straps in various materials, made in Italy with reinforced shoulders and correctly sized keepers suited to the Superocean case profile.

How long does a leather strap last on a Breitling Superocean?

Longevity depends on exposure to water, perspiration and UV light. On a diver such as the Superocean, a quality vegetable-tanned leather strap, properly maintained and kept away from immersion, typically lasts between two and four years. Alligator leather, thanks to the natural structure of its scales, tends to resist moisture better than standard calf. Milano Straps provides an 18-month warranty against manufacturing defects.
