Strap for Superocean 42

The lug width of the Breitling Superocean A1736402BA31131A is 20mm. This measurement refers to the internal distance between the two lugs of the case and determines the exact width of any compatible strap. We recommend verifying this with a digital calliper before purchasing a replacement strap.

The ideal choice depends on the intended use and desired aesthetic. For a sport-elegant combination, a vegetable-tanned alligator strap with a matte finish provides the most refined result. For daily wear, a quality calfskin develops an authentic patina over time. A vulcanised rubber strap or a nylon NATO strap remains the most coherent option with the Superocean's dive instrument identity.

Strap replacement requires a spring bar tool to remove the spring bars securing the strap to the lugs. This can be carried out independently with the appropriate tools, or entrusted to a watchmaker or the Casati Milano atelier. Care should be taken not to apply excessive pressure to the lugs to avoid scratching the case.

Yes. Any strap with a 20mm lug width is compatible with the Breitling Superocean A1736402BA31131A. Milano Straps offers a curated selection of handcrafted Italian straps in various leathers and materials, available with a standard buckle or steel deployant clasp, all produced to fit this exact lug width.

Longevity depends on leather quality, frequency of use, and exposure to perspiration and moisture. A quality artisan strap in vegetable-tanned leather or alligator, with regular maintenance (leather conditioner, natural drying), can last between 3 and 7 years. For aquatic use, rubber or NATO straps are preferable, reserving leather for dry-wear occasions.
