Strap for Superocean Heritage 46 Chronograph Stainless Steel / Black / Gun Blue / Calf

The Breitling Superocean Heritage 46, reference A1332024.C817.441X, features a lug width of 24mm. This is one of the widest lug widths found on contemporary dive watches, proportionate to the 46mm case diameter. To verify it, measure the internal distance between the two lugs at the strap attachment point using a digital calliper.

For the Superocean Heritage 46, we recommend alligator belly straps (wide grain, ideal for large cases), vegetable-tanned calfskin for an authentic vintage aesthetic, NATO nylon for sporting use, or vulcanised rubber for water exposure. The correct lug width is 24mm. A brushed steel deployant clasp is preferable to balance the weight of the case.

To replace the strap on the Superocean Heritage 46, use a dedicated spring bar tool or a flat-head precision screwdriver to release the spring bars from the lugs. Rest the watch on a soft surface to avoid scratching the bezel or caseback. Always verify the replacement strap has a lug width of 24mm before purchasing.

Yes, a wide range of aftermarket straps are compatible with the Breitling Superocean Heritage 46, provided they feature the correct 24mm lug width. Milano Straps offers a curated selection of handcrafted leather straps (alligator, calfskin, cordovan) and technical materials made specifically for this model, offering quality comparable to original Breitling straps with greater scope for personalisation.

The lifespan of a leather strap depends on the material and conditions of use. A vegetable-tanned calfskin strap, with daily wear and proper care (kept away from water and excessive perspiration), typically lasts 2–4 years. Alligator, being denser and more resilient, can exceed 5 years. Shell cordovan is among the most durable options. Casati Milano straps carry an 18-month warranty against manufacturing defects.
