Strap for Superocean Heritage B31 Automatic 44 Stainless Steel / Black / Milanese

The lug width of the Breitling Superocean Heritage AB3112241B1A1 is 22mm. This measurement is consistent across all production examples of this reference, allowing compatibility with any 22mm strap fitted with a standard buckle or deployant clasp.

The ideal choice depends on intended use. For marine environments and sport, vulcanised rubber offers the most practical solution. For formal or business settings, a vegetable-tanned calf leather strap in navy blue or black, or an alligator strap in graphite, complements the ceramic and stainless steel case admirably. A NATO nylon strap remains the most versatile option for everyday wear.

Strap replacement requires a spring bar tool or lug lever. Compress the spring bar between the lugs, slide out the existing strap, and fit the new 22mm strap. The operation takes only a few minutes without specialist tools. It is advisable to rest the watch on a soft pad to protect the ceramic bezel from scratches during the process.

Yes. Any strap with a 22mm attachment width is technically compatible. Milano Straps offers a curated artisanal selection in leather, rubber, and nylon specifically chosen for high-end diving watches such as the Superocean Heritage, with brushed stainless steel or black PVD buckles and deployant clasps in 20mm closing width.

Longevity depends on use and leather quality. A vegetable-tanned calf leather strap, kept away from prolonged water exposure and heavy perspiration, typically lasts between two and four years. Top-quality alligator or shell cordovan straps, regularly treated with leather conditioner, can exceed five years while retaining their patina and structural integrity. Milano Straps provides an 18-month warranty against manufacturing defects.
