Strap for Superocean Heritage II 42 Stainless Steel / Black / Black / Rubber / Pin

The lug width of the Breitling Superocean Heritage AB201012/BF73/278S/A20S.1 is 22mm. This measurement is taken between the two lugs, perpendicular to the strap axis. For maximum accuracy, a digital calliper is recommended over a soft tape measure.

For the Superocean Heritage 42mm, the most coherent options relative to its diver character are: vulcanised rubber for aquatic and sporting use, Hornback alligator for a refined pairing, vegetable-tanned calfskin for daily wear that develops a natural patina over time, and woven nylon NATO for vintage-accurate reference to the 1950s origins of the model.

The strap is removed by compressing the spring bars that attach it to the case lugs. Using a spring bar tool, compress the spring bar ends and slide the strap free. The Superocean Heritage features straight lugs that allow straightforward access. Always work on a soft surface to protect the case from scratches during the operation.

Yes. Any strap with a 22mm attachment width and standard 1.5mm spring bars is fully compatible. milanostraps.it offers a curated selection of handcrafted 22mm straps in leather, rubber and NATO — all interchangeable with the original Breitling strap without any modification to the case.

The lifespan of a leather strap depends on hide quality and exposure to external agents. On a diver such as the Superocean Heritage, regular contact with salt water or chlorinated water accelerates fibre degradation. A quality alligator or calfskin strap used for formal or everyday wear without water immersion can last between 2 and 5 years with proper care. Rubber or nylon is recommended for aquatic use.
