Strap for SuperOcean Deep Sea

The Breitling Superocean 81190 has a lug width of 20mm. This measurement is taken with a digital calliper positioned between the lugs at their narrowest point, flush against the case. The lugs feature a slight inward curve, so curved-end straps are recommended to ensure a flush, gap-free fit against the case.

The ideal choice depends on context. For formal or business-casual wear, a square-scale alligator or shell cordovan strap paired with a steel deployant clasp complements the 39mm case without overwhelming it. For water-related or sporting use, a tropical rubber strap or ballistic nylon NATO offers waterproofing and easy cleaning. A vegetable-tanned calfskin strap strikes the best balance for daily wear, developing a rich patina over time.

Strap replacement requires a springbar tool to compress and remove the 20mm springbars connecting the strap to the lugs. Once removed, slide in the new strap and reinsert the springbars until they click securely into the lug holes. Before proceeding, ensure the replacement strap has curved ends compatible with the Superocean's lug geometry. The entire process takes approximately two minutes and does not require a watchmaker.

Yes. The 20mm lug width is a widely adopted industry standard, and high-quality aftermarket options are plentiful. Milanostraps.it offers a curated selection of 20mm handcrafted straps — in alligator, calfskin, shell cordovan, rubber, and NATO — selected for geometric compatibility with the curved lugs typical of Breitling divers. For a fully bespoke result, Casati Milano's atelier crafts made-to-measure curved-end straps.

Longevity depends on material and frequency of use. A quality vegetable-tanned calfskin strap typically lasts 18 to 36 months under daily wear before structural integrity is compromised. Shell cordovan, owing to its dense fibre structure, often exceeds 3 to 4 years with proper conditioning. Alligator leather, kept away from saltwater and treated with nourishing cream, can maintain its form for several years. All Casati Milano straps from milanostraps.it carry an 18-month warranty against manufacturing defects.
