Strap for Superocean Chronograph 42 Stainless Steel / Blue / Rubber / Pin

The lug width of the Breitling Superocean A13311D1/C971/148S/A18S.1 is 22mm. This measurement is determined by the geometry of the 42mm case and is the essential reference when selecting any compatible aftermarket strap.

The ideal choice depends on the intended use. For aquatic or sporting environments, vulcanised rubber is the most coherent option given the Superocean's diving heritage. For formal or dress-sport occasions, a square-grain Mississippiensis alligator or a vegetable-tanned calf leather strap enhances the dial without compromising the watch's character. A NATO nylon strap remains the most versatile and historically appropriate option for a tool watch of this calibre.

Strap replacement requires a fine-tipped spring bar tool to release the spring bars from the 22mm lugs. If the original integrated bracelet is fitted, it must first be detached from the case before the spring bars can be accessed. Work on a soft surface to avoid scratching the bezel or case. If in doubt, a watchmaker or the Casati Milano atelier can complete the operation in a matter of minutes.

Yes: any strap with a 22mm attachment width is technically compatible. Milano Straps offers a curated selection of handcrafted straps in leather, alligator, calf, rubber and NATO nylon, made with premium materials and available in bespoke versions through the Casati Milano atelier.

Longevity depends on the material and conditions of use. A vegetable-tanned calf strap, with regular conditioning and protection from prolonged water exposure, can last 3–5 years, developing a distinguished patina over time. Alligator leather, thanks to the natural structure of its scales, is more resistant to surface wear and can exceed 5 years of regular use. Vulcanised rubber offers the greatest longevity in aquatic contexts. Milano Straps provides an 18-month manufacturing warranty on all Casati Milano straps.
