Strap for Superocean Heritage B31 Automatic 40 Stainless Steel / Black / Rubber

The Breitling Superocean Heritage AB3110241B1S1 requires a strap with a lug width of 20mm. This measurement refers to the internal distance between the two lugs of the case and is the essential parameter for selecting a compatible strap. Using a digital calliper positioned between the lugs ensures an accurate reading.

The ideal choice depends on the context. For formal occasions, a hornback alligator strap in 20mm complements the steel and ceramic case beautifully. For everyday or active wear, vegetable-tanned calfskin develops a distinctive patina over time. For aquatic environments, vulcanised rubber or a heavy-weave nylon NATO strap offer the best resistance to salt water and moisture.

Strap replacement requires a springbar tool or a fine-blade screwdriver. Compress the springbars fitted within the 20mm lugs to release the existing strap, then insert the replacement. Work on a soft surface to avoid scratching the steel case or ceramic bezel. If in doubt, a watchmaker or the Casati Milano atelier can carry out the operation safely.

Yes. Any strap with a 20mm lug width is compatible with the Breitling Superocean Heritage AB3110241B1S1, provided the springbars have the correct diameter for Breitling lugs. Milanostraps.it offers a curated selection of handcrafted 20mm straps in leather, NATO, and rubber, available in multiple lengths to suit different wrist sizes.

The lifespan of a leather strap depends on the quality of the hide, the tanning method, and daily care. An alligator or vegetable-tanned calfskin strap, kept away from prolonged water exposure and conditioned regularly, can last between 3 and 7 years while retaining its structural integrity. Casati Milano straps carry an 18-month warranty against manufacturing defects.
