Strap for Superocean Heritage 38 Stainless Steel / Blue / Rubber

The native lug width of the Breitling Superocean Heritage A3732024.C735 is 20mm. This measurement should be taken internally between the lugs using a calliper. Any standard 20mm strap is compatible without modification.

The choice depends on intended use: vegetable-tanned calfskin suits versatile daily wear, alligator elevates the formal register, nylon NATO remains truest to the diver heritage, and vulcanised rubber is preferable for sport use or water exposure. Lug width: 20mm.

The strap is replaced using a dedicated springbar tool. Remove both springbars from the lugs, slide out the old strap and insert the new one with the same spring bars. The operation takes under five minutes and requires no professional tools, though care should be taken to avoid scratching the case.

Yes. Any aftermarket strap with a standard 20mm width and springbar fitting is compatible with the Superocean Heritage 38mm. Milanostraps.it offers a curated selection of handcrafted leather, NATO and rubber straps for 20mm lugs, including alligator and shell cordovan options made by Casati Milano atelier.

Longevity depends on the material and conditions of use. A quality calfskin strap, properly maintained and kept away from prolonged moisture, typically lasts 2–4 years. Vegetable-tanned alligator, being denser and less porous, can exceed 5 years. Casati Milano straps carry an 18-month warranty against manufacturing defects.
