Strap for Superocean Heritage II 46 Chronograph Stainless Steel / Black / Black / Croco / Folding

The lug width of the Breitling Superocean Heritage A1331212/BF78/761P/A20D.1 is 24mm. This measurement is specific to the 46mm case variant and is not shared with smaller diameter versions within the same family. For an accurate measurement, use a vernier calliper positioned internally between the lugs, parallel to the strap axis.

The ideal choice depends on the context of use. For formal or business settings, an alligator strap in vegetable-tanned leather paired with a stainless steel deployant clasp best complements the chronograph's character. For daily wear, Tuscan calf leather develops a genuine patina over time. For aquatic use, vulcanised rubber ensures durability and quick drying. All straps must feature a straight end and a 24mm lug width.

Strap replacement uses standard 24mm spring bars. A flat-tipped spring bar tool or a dedicated strap-change screwdriver is required to compress the spring and release the existing strap. No watchmaker intervention is needed if the correct tools are available. It is advisable to work on a soft surface to prevent scratches to the case or lugs.

Yes. The Breitling Superocean Heritage 46mm uses straight 24mm lugs, a width widely supported by the aftermarket. Milano Straps produces bespoke handcrafted straps compatible with this model, available in leather, alligator, calf, rubber and NATO styles. It is essential to confirm that the strap end is straight rather than curved to ensure a proper fit against the case lugs.

The lifespan of a leather strap depends on tanning quality and conditions of use. A high-quality vegetable-tanned strap worn daily without prolonged exposure to water or perspiration will maintain structural and aesthetic integrity for 2 to 4 years. Regular exposure to salt water significantly reduces leather longevity; in such cases, alternating with a rubber or NATO strap is strongly recommended. Applying a leather conditioner every 3 to 4 months will extend the strap's service life considerably.
