Strap for Superocean Heritage B31 Automatic 42 Stainless Steel / Black / Rubber

The lug width of the Breitling Superocean Heritage AB3111241B1S1 is 22mm. This measurement refers to the internal distance between the two lugs of the case and determines compatibility with any aftermarket strap. It is essential to measure the lugs accurately before purchasing a replacement strap.

For the 42mm Superocean Heritage in ceramic and stainless steel, the most suitable options are: matte alligator in midnight blue or cognac for formal wear, vegetable-tanned calfskin for natural patina development, nylon NATO for the watch's original nautical vocation, and vulcanised rubber for aquatic use. The correct lug width is 22mm.

To replace the strap, the two spring bars securing it to the case lugs must be removed. A spring bar tool is inserted between the lug and the strap end to compress and release each bar. The operation can be performed without professional tools, though care should be taken to avoid scratching the ceramic bezel or the steel case.

Yes, any standard 22mm strap fitted with spring bars is compatible with the Breitling Superocean Heritage AB3111241B1S1. Milano Straps offers handcrafted straps in alligator, calfskin, vegetable-tanned leather and NATO, specifically selected for this reference, with finishes and stitching designed to complement the heritage diver aesthetic of Breitling.

The lifespan of a leather strap depends on the quality of the tanning process, frequency of use and maintenance. A high-quality vegetable-tanned leather strap, kept away from prolonged water exposure and regularly treated with a conditioning cream, typically lasts between 3 and 5 years with daily wear. For intensive or water-related use on a diver such as the Superocean Heritage, a rubber or NATO strap is advisable.
