Strap for Superocean II 42 Stainless Steel / Blue / Japan Special Edition

The lug width of the Breitling Superocean A17365D1/C957/161A is 20mm. This is a widely used standard size, compatible with a broad range of aftermarket and bespoke straps. For an accurate measurement, use a digital calliper to measure the internal gap between the lower lugs of the case.

The ideal choice depends on context: for formal or business-casual wear, a vegetable-tanned alligator or box calf leather strap complements the black dial and the brushed steel finish elegantly. For everyday sporting use, vulcanised rubber or ballistic nylon NATO straps are more consistent with the diver's technical vocation. In all cases, the correct lug width is 20mm.

Strap replacement requires a fine-tipped springbar tool. Insert the tip into the springbar slot inside the lug, compress the spring end until it releases, and slide the strap free. To avoid scratching the steel lugs, protect the case with masking tape or a soft cloth. The replacement strap must have straight ends in 20mm width.

Yes: the 20mm lug width is a universal standard, compatible with any aftermarket strap featuring straight ends. milanostraps.it offers a curated selection of handcrafted straps in alligator, calf leather, shell cordovan and rubber, with bespoke options available through the Casati Milano atelier. Compatibility is guaranteed for all standard 20mm lug widths.

Longevity depends on leather quality, tanning method, and frequency of use. A high-quality vegetable-tanned alligator strap can last between three and five years with daily wear, developing a distinctive patina over time. Quality calf leather and shell cordovan offer comparable performance. Prolonged exposure to seawater or perspiration accelerates deterioration; for a diver worn in water, a rubber or NATO strap is strongly recommended.
