Strap for Superocean Heritage B31 Automatic 40 Stainless Steel / Green / Milanese

The lug width of the Breitling Superocean Heritage AB3110361L1A1 is 20mm. This measurement is taken internally between the two lower lugs of the case using a calliper. Any aftermarket strap with a 20mm attachment is compatible with this reference.

The ideal choice depends on intended use. For formal occasions, alligator leather or vegetable-tanned calf provides a refined complement to the steel and ceramic case. For sporting or nautical use, vulcanised rubber offers the most functional solution. Ballistic nylon NATO straps echo the original Superocean military spirit. All options require a 20mm attachment.

The strap is replaced by removing the two spring bars that secure it to the case lugs, using a dedicated springbar tool. The operation does not require opening the caseback or professional intervention, but it is advisable to work on a soft surface to avoid scratching the case or the ceramic bezel. The replacement strap must have a 20mm attachment.

Yes. Any strap with a 20mm attachment is technically compatible with the Breitling Superocean Heritage AB3110361L1A1. Milanostraps.it offers a curated selection of handcrafted leather, rubber and nylon straps in this size, produced with materials and finishing standards comparable to the original Breitling offering.

The lifespan of a leather strap depends on the quality of the hide, frequency of use and exposure to perspiration and water. A high-quality vegetable-tanned calf or alligator strap, worn daily under normal conditions, typically lasts between 18 and 36 months. Casati Milano straps carry an 18-month warranty against manufacturing defects.
