Strap for Superocean Heritage 46 Stainless Steel / Black / Stratus Silver / Rubber

The lug width (or strap width) of the Breitling Superocean Heritage A1732024.G642.135S is 24 millimetres. This measurement is fixed and determined by the geometry of the 46mm case. To verify it, measure the internal distance between the two lugs where the strap attaches to the case. Any compatible strap must feature this exact width to ensure secure attachment without mechanical play.

For the Superocean Heritage, we recommend alligator leather in burnt cognac tone, which creates an elegant contrast with the stainless steel case. If you require superior durability for frequent diving, shell cordovan in dark brown offers natural water resistance and exceptional longevity. For everyday wear and aesthetic versatility, vegetable-tanned calf leather develops a stunning patina over time. Your choice depends on primary use: aesthetic, sporting, or professional.

Strap replacement requires a dedicated spring bar tool. Remove the current spring bars—the small elastic pins at each lug—by gently levering both ends simultaneously. Insert the new spring bars into the end of the new strap's lug holes, then carefully press the spring bar into place on the case. Ensure the strap lug terminals align perfectly with the case slots before final insertion. If uncertain, consult a professional watchmaker or Casati Milano atelier for professional replacement service.

Yes, any strap with a 24-millimetre lug width is mechanically compatible with the Breitling Superocean Heritage A1732024.G642.135S. Compatibility is guaranteed by identical strap width. Milano Straps offers a curated selection of 24mm artisanal straps in premium leathers—alligator, calf, shell cordovan—with construction quality comparable to original Breitling straps, at a fraction of the price. You can customise length, colour, initials, and buckle type.

Leather strap durability depends on material and usage patterns. A quality alligator or vegetable-tanned calf strap typically lasts 3–5 years with daily wear but no regular diving. Shell cordovan can endure 7–10 years owing to its natural fibrous structure. If the strap experiences regular saltwater immersion and diving, lifespan reduces to 2–3 years; in such cases, vulcanised rubber or NATO fabric offer more economical alternatives. Casati Milano straps include an 18-month warranty against manufacturing defects.
