Strap for Superocean Heritage II 46 Chronograph Stainless Steel / Bronze / Bronze / Croco / Folding

The lug width of this model is 24 millimetres, a non-standard measurement that reflects Breitling's design philosophy regarding aesthetic proportion. The 24mm width allows the strap to integrate visually with the 46mm case without appearing disproportionate. This specification excludes compatibility with smaller lug widths (22mm or 20mm), making it essential to verify the exact technical specification before purchasing any strap.

There is no single 'best' choice; instead, various options suit different contexts. Alligator represents the pinnacle from a formal aesthetic perspective, with natural grain that harmonises with the ceramic bezel. Vegetable-tanned calf leather offers chromatic evolution over time and environmental consciousness. Shell cordovan emphasises elegant character with superior structural rigidity. NATO fabric straps and vulcanised rubber are ideal for intensive aquatic use, providing superior grip and durability in extreme moisture conditions.

Strap replacement is achieved by removing the spring bars that secure the strap to the lugs. Using a dedicated spring bar remover tool, compress the internal spring of the bar to free one lug, then repeat the operation for the opposite side. Insert the new strap by aligning the holes with the lugs and pushing the spring bar until it clicks into place. It is advisable to work on a clean, well-lit surface to prevent loss of small components.

Yes, all straps with a 24-millimetre lug width are mechanically compatible. Verify that the spring bars of the strap are of correct length for the Superocean Heritage lugs. MilanoStraps offers a comprehensive range of 24mm straps customisable in leather (alligator, calf, shell cordovan), NATO fabric and rubber, all tested for compatibility and build quality.

Durability varies depending on the leather type used, exposure to moisture and perspiration, and construction quality. An alligator or shell cordovan strap with vegetable tanning, worn daily in temperate climate, typically lasts 3-4 years before requiring replacement. Frequent exposure to water, perspiration and ultraviolet rays accelerates ageing. A vulcanised rubber strap, specifically formulated for aquatic environments, demonstrates superior longevity under identical conditions. Casati Milano guarantees 18 months on their bespoke production.
