Strap for Superocean II 36 Diamond / White / Sahara

The lug width of the Breitling Superocean A1731267.A775.251X is 18mm. This measurement should be taken with a vernier calliper across the internal distance between the two lugs, excluding the outer shoulders. Respecting this dimension is essential to ensure a correct fit without lateral play on the replacement strap.

The choice depends on intended use. For formal occasions, a vegetable-tanned alligator strap with a steel deployant clasp offers elegance and longevity. For sport or aquatic use, vulcanised rubber is the most technically appropriate solution. Shell cordovan provides an excellent balance between durability, patina development over time, and a slim profile on the wrist. All options must feature an 18mm attachment width.

To replace the strap, a fine-tipped spring bar tool is required. Insert the tip into the lug hole to compress the spring bar, then slide the strap free. This operation should be carried out carefully to avoid scratching the satin-finished case surfaces. If in doubt, it is advisable to entrust the task to a watchmaker or to the Casati Milano atelier during a strap fitting service.

Yes. Any strap with an 18mm attachment is dimensionally compatible with the Breitling Superocean A1731267.A775.251X. However, the quality and precision of the lug-end finishing varies considerably between manufacturers. Casati Milano produces straps with tapered ends crafted specifically for this case profile, ensuring a perfect fit and no lateral play at the lug.

Longevity depends on the leather type and conditions of use. A quality vegetable-tanned alligator strap, kept away from prolonged water exposure and excessive perspiration, can last between three and five years. Shell cordovan, owing to its compact, closed-pore structure, tends to last longer whilst developing a distinctive patina. Casati Milano provides an 18-month guarantee against manufacturing defects on all straps produced in the atelier.
