Strap for Superocean Heritage II 46 Stainless Steel / Black / Silver / Calf / Pin

The lug width of the Breitling Superocean Heritage AB202012/G828/439X/A20BA.1 is 24mm. This is a notably wide measurement, proportionate to the 46mm case diameter, and requires straps specifically made to 24mm to ensure a precise fit between the lugs with no lateral play.

The ideal choice depends on intended use. For daily urban wear, a 24mm vegetable-tanned calfskin strap offers comfort and develops an authentic patina over time. For formal or collector contexts, an alligator strap with a deployant clasp is the most refined option. For aquatic or sporting use, vulcanised rubber or ballistic nylon NATO straps provide the most practical solution.

The strap is replaced using a spring bar tool to remove the spring bars connecting the strap to the case lugs. Care should be taken to avoid scratching the stainless steel case: use a protective cloth and work under adequate lighting. Alternatively, any equipped watchmaker or jeweller can perform the swap in a matter of minutes.

Yes. All standard 24mm straps are compatible with the Breitling Superocean Heritage 46mm. Milano Straps offers a curated selection of handcrafted leather, rubber and textile straps specifically calibrated to the 24mm lug width, available bespoke or ready to purchase online.

The lifespan of a leather strap depends on material quality and frequency of use. A high-quality vegetable-tanned calfskin strap, worn daily, typically lasts between 12 and 24 months before the buckle holes or edges show significant wear. Alligator and shell cordovan, due to their denser fibre structure, tend to last considerably longer. Exposure to water or heavy perspiration significantly reduces longevity: rubber or NATO straps are preferable in such conditions.
