Strap for Superocean 42

The Breitling Superocean A1736402BA28132S features a lug width of 20mm. This measurement is taken with a digital calliper placed inside the lugs, flush against the case, measuring the clear distance between the two lug walls. Any aftermarket strap with a standard 20mm fitting is compatible with this reference.

The ideal choice depends on context. For aquatic or sporting use, a vulcanised rubber strap or a technical nylon NATO strap offers maximum functionality and resistance. For formal or business-casual settings, an alligator strap with bombé grain or a vegetable-tanned calf strap enhances the 42mm steel case without compromising the Superocean's nautical identity.

Strap replacement is carried out via the spring bars — the small pin mechanisms connecting the strap to the case lugs. Using a forked spring bar tool, compress each spring bar, slide the existing strap free, and fit the new one in reverse order. The process takes approximately two minutes per side and requires no professional equipment, provided a dedicated tool is used to avoid scratching the case.

Yes. Any strap with a standard 20mm fitting is compatible.

A quality leather strap — particularly in vegetable-tanned calf or alligator — typically lasts 2 to 4 years with daily wear, provided it is kept away from prolonged exposure to water, excessive perspiration, and direct sunlight. Storing the strap in a dry environment when not in use and applying a leather conditioner periodically will significantly extend its lifespan. Milanostraps.it straps carry an 18-month warranty against manufacturing defects.
