Strap for SuperOcean Automatic 42 Stainless Steel - Red Gold / Black - Red / Bucherer

The lug width of the Breitling Superocean U173752A1B1S1 is 22 mm. This is the standard measurement used by Breitling across the principal references of the 42 mm Superocean line. To verify it independently, measure the internal distance between the two lugs using a digital calliper placed flush against the case.

The ideal choice depends on the intended use. For formal or dress occasions, a vegetable-tanned alligator strap in 22 mm complements the ceramic and red gold combination of the case with great refinement. For aquatic or active use, a vulcanised rubber strap with a steel deployant clasp offers maximum performance. A premium nylon NATO strap suits a robust, casual aesthetic.

The strap is replaced using standard 22 mm spring bars. Use a proper spring bar tool, applying gentle lever pressure within the lug slot to avoid scratching the stainless steel case or the ceramic bezel. Alternatively, a watchmaker or the Casati Milano atelier can perform the fitting as part of a bespoke strap service.

Yes. Any strap with a 22 mm attachment width is fully compatible with the Breitling Superocean U173752A1B1S1. Milano Straps offers a curated selection of handcrafted 22 mm straps in leather, rubber and nylon, made with carefully sourced materials and hand-finished edges, specifically designed for high-end sport watches of this calibre.

The lifespan of a leather strap depends on material quality and conditions of use. A high-grade vegetable-tanned alligator strap, with periodic conditioning and limited exposure to water, can last between three and five years whilst developing a distinguished patina. For frequent contact with water or perspiration, rubber or shell cordovan are structurally better suited alternatives.
