Strap for Superocean 44

The Breitling Superocean A1739102BA77134A has a lug width of 22mm. This measurement is taken with a vernier calliper between the inner faces of the lugs and determines the correct strap width at the point of attachment. It should not be confused with the case diameter (44mm) or the buckle width, which is typically 2–4mm narrower than the lug width.

The ideal choice depends on context. For aquatic and sporting use, a 22mm vulcanised rubber strap with a brushed steel buckle is the most functional option. For everyday wear, a vegetable-tanned calf leather strap with a tight grain develops a lasting patina that complements the blue dial. For formal occasions, a Mississippiensis alligator strap with a centre-cut belly, in matte or gloss finish, introduces an unexpectedly refined aesthetic without compromising the case's muscular character. In all cases, use quality 22mm steel spring bars.

Strap replacement requires a spring bar tool or a thin flat-head screwdriver to release the spring bars seated in the lugs. The Superocean's spring bars feature a ball-end design: compress them from the outer edge of the lug rather than centrally. Work on a soft cloth to protect the steel surfaces. The process takes approximately 2–3 minutes for those familiar with watchmaking tools. Alternatively, any watchmaker or the Casati Milano atelier can perform the swap without risk of scratching.

Yes. Any 22mm strap with straight or slightly curved ends is compatible with this model. Milanostraps.it offers a curated selection of handcrafted 22mm straps in various materials — alligator, calf, cordovan, NATO and rubber — all supplied with spring bars and a steel buckle or butterfly deployant clasp. Compatibility is assured by the standard 22mm lug width shared by many professional-grade dive watches.

Longevity depends on material and usage. A quality vegetable-tanned calf leather strap worn daily without heavy water or perspiration exposure will typically last 2–4 years before structural wear becomes apparent. Alligator leather, being denser and less porous, can last 4–6 years under similar conditions. For regular sporting use or water contact, vulcanised rubber is strongly recommended as it is impervious to moisture degradation. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
