Strap for Superocean Heritage '57 Highlands / Beige

The lug width of the Breitling Superocean Heritage '57 U10340E31A1A1 is 20mm. This measurement is confirmed by Breitling's official specifications and refers to the internal distance between the two lugs, measured at the narrowest point. For a proper fit, it is advisable to ensure that any aftermarket strap features curved ends compatible with the lug profile of this specific model.

Given the two-tone red gold and stainless steel case of the Superocean Heritage '57, a vegetable-tanned alligator strap with a deployant clasp represents the most technically and aesthetically coherent pairing. Tobacco, cognac or midnight blue tones complement the warmth of the red gold without overpowering it. A blue-and-white NATO strap is a strong alternative that references the model's original diving heritage. Vulcanised rubber is recommended for aquatic use.

The strap on the Superocean Heritage '57 is replaced using standard 20mm spring bars. A fine-tipped springbar tool is sufficient to compress the bars and remove the original strap. It is recommended to work on a soft surface to protect the case and crystal. When fitting curved-end straps, ensure the radius of curvature is compatible with the lug profile before installation.

Yes. Any strap with a 20mm lug width is technically compatible with the Superocean Heritage '57. For the best aesthetic result, straps with curved ends suited to Breitling's lug profile are recommended. Milano Straps offers a curated selection of handcrafted leather, rubber and nylon straps specifically available in 20mm, with a bespoke option through the Casati Milano atelier.

The lifespan of a leather strap depends on the quality of the tanning process, frequency of use and daily care. A high-grade vegetable-tanned alligator strap, with regular but non-intensive use, typically lasts between 3 and 5 years before showing structural wear at the flex points. Periodic conditioning with a cream specific to exotic leathers, and rotating between multiple straps, will significantly extend its service life. Casati Milano straps carry an 18-month warranty against manufacturing defects.
