Strap for Superocean Heritage 42 Stainless Steel / Black / Stratus Silver / Calf

The Breitling Superocean Heritage A1732124.G717.435X has a lug width of 22mm. This measurement should be confirmed using a digital calliper placed inside the lug gap, flush against the case, to account for any manufacturing tolerances.

For formal wear, a glossy alligator strap in navy or slate grey pairs elegantly with the case's brushed and polished finishes. For daily use, vegetable-tanned Tuscan calfskin in tobacco develops a distinguished patina. For aquatic or sporting contexts, vulcanised rubber or heavy-duty NATO nylon are the more technically appropriate choices.

Use a 1.5mm spring bar tool inserted into the lateral slot of the springbar. Work on a soft surface to protect the bezel and screwback caseback. The original Breitling springbar has a diameter of 1.8mm — verify compatibility with the replacement strap's springbar before fitting.

Yes. Any strap with a straight-end 22mm fitting is compatible. Milano Straps offers a curated range of handcrafted leather, rubber and textile straps sized for 22mm lug widths, with straight ends suited to the Superocean Heritage's lug geometry.

A quality vegetable-tanned leather strap, if not regularly exposed to salt water, typically lasts 2–4 years with daily wear. Perspiration and sea water accelerate degradation, particularly at the buckle end and beneath the case. For aquatic use, rubber or NATO straps are recommended; leather suits mixed use provided it is dried regularly.
