Strap for Superocean II 36 Black / Rubber

The lug width of the Breitling Superocean A17312C9.BD91.237S is 18mm. It is measured using a digital calliper across the internal gap between the two lugs, flush against the case. Any strap with an 18mm attachment is compatible with this reference.

For the Superocean 36 in satin-finished steel, an alligator strap in vegetable-tanned leather or a box-calf strap enhances the restrained case diameter and suits an urban context. For sporting or warm-weather use, a technical nylon NATO or a vulcanised rubber strap provide durability and water resistance. A steel deployant buckle completes the pairing with material coherence.

The strap is removed using a flat-tip spring bar tool or a strap-changing knife, applying gentle pressure on the spring bar connecting the strap to the case lugs. The operation does not require professional tools, but it is advisable to work on a soft surface to avoid scratching the case. Each side can be swapped in under two minutes.

Yes. Any strap with an 18mm attachment width is compatible with the Breitling Superocean A17312C9.BD91.237S. MilanoStraps offers a curated selection of handcrafted straps in leather, alligator, shell cordovan and technical materials, available as bespoke commissions or ready-to-ship, all dimensioned to fit the lugs of this reference correctly.

The lifespan of a leather strap depends on the quality of the tanning, frequency of use and exposure to moisture and perspiration. A quality vegetable-tanned calf leather strap typically lasts 2 to 4 years with daily wear. Shell cordovan, owing to the compact fibre structure of the horse's sub-cutaneous membrane, offers superior longevity and develops a distinguished patina over time. MilanoStraps provides an 18-month warranty against manufacturing defects.
