Strap for Superocean Heritage '57 Stainless Steel / Rainbow Boutique Limited Edition / Calf / Pin

The lug width of the Breitling Superocean Heritage '57 A103701A1B1X1 is 20mm. This measurement should be taken with a digital calliper directly between the inner surfaces of the two lugs to ensure precise compatibility with any replacement strap.

The most suitable materials for the Superocean Heritage '57 are vegetable-tanned calf leather for everyday vintage wear, alligator for formal occasions, nylon NATO for sporting use, and vulcanised rubber for wet or marine environments. The choice depends on the primary use and dial colour: with a black dial, a cognac or tobacco calf strap provides the most balanced chromatic contrast.

To replace the strap, you will need a 20mm spring bar and a dedicated spring bar tool or a very thin flat-head screwdriver. Insert the tool into the side hole of the spring bar, compress the spring and slide the strap out of the lug. The operation is fully reversible and does not require a watchmaker, but care should be taken to avoid scratching the stainless steel case.

Yes. Any strap with a 20mm lug width is technically compatible. Milano Straps offers a curated selection of handcrafted leather, alligator, rubber and NATO straps specifically sized for 20mm lugs, with tapered ends suited to the typical curvature of Breitling cases.

A quality leather strap, properly maintained, typically lasts between 18 and 36 months of daily wear. Longevity depends on exposure to perspiration, water and UV radiation. Vegetable-tanned leather straps, if treated periodically with natural wax or conditioning cream, develop a desirable patina and tend to outlast chrome-tanned alternatives.
