Strap for SuperOcean Automatic 46 Stainless Steel / Black / Rubber

The Breitling Superocean A17378211B1S1 has a lug width of 24mm. This generous measurement is proportional to the 46mm case diameter. To verify it, use a digital calliper to measure the internal distance between the two lugs at their narrowest point.

For water use, a vulcanised rubber strap in 24mm is the most functional choice. For urban or formal settings, an alligator or vegetable-tanned calf leather strap develops a distinguished patina that complements the ceramic bezel. A ballistic nylon NATO strap is ideal for everyday robustness and versatility.

Use a spring bar tool to release the strap. Insert the forked tip between the lug and the strap end, compress the spring bar and slide the strap free. Take care not to scratch the ceramic bezel during the operation. Casati Milano also offers an in-atelier strap change service by appointment.

Yes. Any strap with a 24mm lug width and appropriate taper is compatible. It is essential that the strap ends are shaped to follow the curved lugs of the 46mm Superocean case. Milanostraps.it offers a curated selection of handcrafted 24mm straps made to fit this reference.

Longevity depends on the material and conditions of use. A high-quality alligator or vegetable-tanned calf strap, kept away from water and treated regularly with leather conditioner, will last between two and five years. Frequent exposure to salt water or chlorine significantly accelerates deterioration; for diving use, a rubber or NATO strap is strongly recommended.
