Strap for Superocean Heritage II B20 Automatic 44 Stainless Steel / Black / Rubber / Folding

The lug width of the Breitling Superocean Heritage AB2030121B1S1 is 22mm. The lugs feature a slight curvature (curved lug ends) that promotes a close fit to the wrist. When selecting a replacement strap, it is essential to verify not only the width but also the end geometry — straight or curved — to ensure a clean, gap-free fit between the strap and the case.

The ideal choice depends on the intended use. For casual or marine environments, a nylon NATO or a perforated rubber strap is most consistent with the watch's diver heritage. For formal or business-casual settings, an alligator strap in black or a vegetable-tanned calf strap in navy blue elevates the aesthetic register without compromising the tool-watch character. The correct width is always 22mm.

Strap replacement requires a fine-tipped spring bar tool. Insert the tip into the spring bar slot between the lug and the strap, compress the spring bar inward, and slide the strap free. Repeat on the opposite side. Before fitting the new strap, confirm the spring bar length (typically 22mm for this reference) and the end geometry. To protect polished steel lugs, apply low-tack adhesive tape to the case before proceeding.

Yes. The aftermarket offers a broad range of 22mm straps compatible with the Breitling Superocean Heritage AB2030121B1S1, including nylon NATO, handcrafted leather, technical rubber, and alligator options. Milano Straps provides hand-finished straps in a variety of leathers, colours and finishes, with the option of full bespoke customisation through the Casati Milano atelier for those seeking a made-to-measure piece.

Strap longevity depends on leather quality, tanning method and frequency of use. A well-made vegetable-tanned calf strap, worn daily and properly maintained — occasional conditioning, natural drying after moisture exposure — typically lasts two to four years. High-grade alligator straps, owing to the denser grain structure, tend to offer greater longevity. Regular exposure to salt water or chlorine significantly shortens the lifespan of any leather strap; in such conditions, rubber or NATO alternatives are strongly advisable.
