Strap for Superocean Heritage II 46 Stainless Steel / Black / Silver / Calf / Pin

The lug width of the Breitling Superocean Heritage AB202012/G828/441X/A20BA.1 is 24 millimetres. This measurement is specific to the 46-millimetre model and is proportioned to the case diameter, ensuring visual balance and wrist stability. Any compatible strap must have a width of exactly 24 millimetres, measured between the lugs of the case.

Selection depends on your intended use. An alligator strap in black is ideal for formal occasions, emphasising contrast with the blue dial and gold accents. Brown or cognac calf leather offers daily versatility whilst maintaining elegance. For outdoor activities or sports use, a robust cotton NATO or vulcanised rubber strap ensures practicality and salt water resistance without compromising readability.

Strap replacement requires a spring bar tool, available in single-tip or bifurcated versions. Position the tool beneath the case lug, gently compressing the internal spring until the spring bar is released. Repeat on the opposite lug. To fit the new strap, insert the two spring bars into the strap ends and compress again with the tool to secure them to the case lugs. Avoid excessive force to prevent damage to the metal coils.

Yes, aftermarket straps with 24-millimetre lug width are compatible and available from specialist retailers such as milanostraps.it. You can select from various materials—leather, alligator, NATO, or rubber—whilst maintaining compatibility with the original case lugs. Ensure the strap explicitly states 24-millimetre width to guarantee a perfect fit.

Leather strap longevity depends on material quality, frequency of use, and maintenance care. A high-quality alligator strap with vegetable tanning can last 8–12 years with regular maintenance (periodic cleaning, protection from excessive humidity and heat sources). More delicate calf leather typically lasts 4–7 years. Standard warranty on bespoke straps is 18 months against manufacturing defects, whilst natural wear is excluded from coverage.
