Strap for Superocean Heritage II 46 Chronograph Stainless Steel / Black / Black / Croco / Pin

The lug width of the Breitling Superocean Heritage A1331212/BF78/756P/A20BA.1 is 24 millimetres. This standard measurement for medium-sized watches is compatible with the vast majority of straps available on the market, whether in leather, fabric, or rubber. It is essential to measure the distance between the two lug pins of the case precisely before ordering a strap to avoid incompatibility.

The ideal strap depends on intended use and personal preference. For an authentic sporty-diving aesthetic, a NATO in technical or heavy cotton material reflects the vintage DNA of the model. For a more refined look, vegetable-tanned calf leather or alligator leather imparts elegance without compromising sportiness. Modern Superocean Heritage models often come fitted with vulcanised rubber straps featuring a hammered texture, ideal for skin contact during immersion.

Changing the strap requires a specific tool to remove the spring bars. Place the watch on a soft surface and use the spring bar remover to gently push the bar inward, releasing the strap from the case. Repeat the operation on the other side. Insert the new strap by aligning the holes with the pins, then snap the pins into position with a firm movement. If you feel uncertain, contact a specialist artisan such as Casati Milano.

Yes, any strap with a 24-millimetre lug width is compatible with the Superocean Heritage. High-quality aftermarket straps—particularly those crafted using artisanal techniques and premium leathers—often offer aesthetic and tactile upgrades compared to factory-standard straps. Milano Straps offers a collection of 24mm straps customisable in natural leather, finishes, and stitching thread, ensuring seamless visual integration with your watch case.

The durability of a leather strap depends on leather quality, frequency of use, and exposure to moisture. A high-quality vegetable-tanned calf leather strap, subject to regular maintenance—gentle cleaning and occasional application of protective balms—can last 3-5 years of daily wear. Constant exposure to water and chlorine, such as with frequent diving, significantly reduces lifespan. For watches intended for intensive water use, a rubber or synthetic material strap is the most practical and durable choice.
