Strap for Superocean Heritage '57 Highlands / Blue

The lug width of the Breitling Superocean Heritage '57 U10340161C1A1 is 20mm. This measurement, taken between the case lugs with a digital calliper, determines compatibility with any aftermarket strap. All 20mm straps in the MilanoStraps catalogue are engineered to this specification.

For the U10340161C1A1 in red gold and stainless steel, the most suitable straps are vegetable-tanned alligator (hornback or mississippiensis grain) in cognac or tobacco tones, or black vulcanised rubber to preserve the diving character. A deployant clasp in polished steel or rose gold PVD completes the pairing with an appropriate level of finishing.

The strap is removed using a spring bar tool or a flat-bladed screwdriver with a blunted tip, levering against the spring bar that secures the strap to the case lugs. Care should be taken to avoid scratching the stainless steel or red gold case. If in doubt, it is advisable to consult a watchmaker or a specialist atelier such as Casati Milano.

Yes. Any strap with a 20mm lug width is technically compatible with the Breitling Superocean Heritage '57 U10340161C1A1, provided the strap ends — straight or curved — match the geometry of the case lugs. MilanoStraps offers a comprehensive selection of handcrafted 20mm straps in leather, rubber, and nylon compatible with this reference.

The lifespan of a leather strap depends on the quality of the tanning process, exposure to water, and frequency of wear. On a diving-oriented watch such as the Superocean Heritage '57, a quality vegetable-tanned alligator strap can last between 2 and 5 years with regular maintenance. For use in humid or marine environments, vulcanised rubber is recommended for superior durability without deterioration.
