Strap for Superocean Heritage '57 Stainless Steel / Calf / Folding

The Breitling Superocean Heritage '57 A10370121B1X2 has a lug width of 20mm. This measurement is taken between the two lugs at the point where they meet the case, ideally using a digital calliper for accuracy.

The ideal choice depends on context. For formal or smart-casual wear, a 20mm alligator or vegetable-tanned calfskin strap enhances the model's heritage character. For sport or water use, a rubber or NATO strap is the more practical option. A stainless steel deployant clasp coordinates well with the case and improves weight distribution on the wrist.

The strap is removed using a flat-tip spring bar tool or a T-shaped lever. The 20mm spring bars are compressed laterally to release from the lugs. The process takes approximately two minutes and requires no professional tools, though working on a soft surface is advisable to avoid case scratches.

Yes. Any strap with a 20mm straight-end attachment is geometrically compatible with the Superocean Heritage '57. Milanostraps.it offers a curated selection of 20mm handcrafted straps by Casati Milano in various materials and finishes, with bespoke options available.

Longevity depends on material and usage. A quality vegetable-tanned calfskin strap, with regular care, typically lasts 2–4 years. Shell cordovan, being denser and more resistant, can exceed 5 years. Frequent exposure to perspiration, salt water or UV light accelerates deterioration; in such conditions, alternating with a rubber or NATO strap is recommended.
