Strap for Superocean Heritage II 46 Stainless Steel / Green / Rubber

The Breitling Superocean Heritage AB2020121L1S1 has a lug width of 24mm. This measurement, relatively uncommon in the sport-luxury segment, is proportionally suited to the 46mm case diameter and requires dedicated straps to ensure correct visual balance and secure spring bar fitment.

The ideal choice depends on intended use. For everyday wear in mixed environments, a vegetable-tanned calfskin strap at 3.5mm thickness offers comfort and develops a distinctive patina over time. For water exposure, vulcanised rubber or ballistic nylon NATO straps are the most practical options. For formal occasions, a matte alligator strap in 24mm is the most refined solution.

The strap is replaced using a spring bar tool — either a flat-head or forked lug tool — to compress the spring bars within the lugs. The operation takes only a few minutes and requires no specialist skills. Place the case on a soft cloth to avoid scratching the ceramic or steel surfaces during the process.

Yes. Any strap with a 24mm attachment width is compatible. Milano Straps offers a curated selection of handcrafted leather, rubber, and NATO straps specifically available in 24mm, with bespoke customisation options through the Casati Milano atelier.

With standard care — rotating between straps, drying away from direct heat sources, and applying a neutral leather conditioner periodically — a vegetable-tanned calfskin strap will last between 2 and 4 years. Alligator leather, being denser and more abrasion-resistant, can exceed 5 years. Regular exposure to salt water significantly reduces longevity; in such cases rubber or NATO straps are strongly recommended.
