Strap for Superocean Heritage B31 Automatic 36 Stainless Steel / Blue / Bracelet

The Breitling Superocean Heritage A10390161C1A1 has a lug width of 20mm. This measurement refers to the internal distance between the two lugs of the case and determines the correct strap width. For precise verification, a digital calliper positioned between the lugs is recommended.

For the 36mm Superocean Heritage, the most coherent choices with the model's identity are: vegetable-tanned calf leather for versatile daily wear, padded alligator for a more formal profile, vulcanised rubber for sporting or marine contexts, and nylon NATO for the most authentic diving heritage look. A stainless steel deployant clasp is recommended for those who prioritise practicality and secure fastening.

Strap replacement requires a fine-tipped or lever-type spring bar tool to compress the strap's spring bars. With the Superocean Heritage, it is advisable to rest the watch on a soft cushion to avoid scratching the ceramic case. If in doubt, Casati Milano offers an in-atelier strap-change service.

Yes. Any strap with a 20mm lug width is compatible with the Superocean Heritage A10390161C1A1, provided the end shape (straight or curved) is correct. milanostraps.it offers a selection of handcrafted 20mm straps in various materials and finishes, all compatible with this Breitling reference.

The lifespan of a leather strap depends on the quality of the tanning, the leather thickness, and usage intensity. A quality vegetable-tanned calf strap, with regular daily wear, typically lasts 2–4 years. Shell cordovan can exceed 5 years thanks to the density of its fibres. For humid or sporting environments, rubber is preferable, offering superior durability and water resistance.
