Strap for Superocean Heritage II 46 Stainless Steel / Bronze / Bronze / Aero Classic / Pin

The lug width is 24mm. This measurement represents the distance between the two pins that attach the strap to the case. To verify it, measure the space between the two side lugs of the case bracket – it must be exactly 24mm to ensure complete compatibility with aftermarket straps.

The choice depends on intended use and aesthetic preference. Alligator is the most sophisticated option, with natural grain that contrasts elegantly against the stainless steel. For those preferring vintage character, shell cordovan develops an intense patina over time. Vegetable-tanned calf leather offers chromatic versatility and progressive ageing. For intensive water use, vulcanised rubber ensures functionality without compromise. NATO fabric provides practicality and rapid strap changes for casual contexts.

Strap change requires a specific tool: a small L-shaped key or watch spring bar tool. Locate the two side pins on the case, insert the tool tip into the slot and rotate gently to remove them. Once the pins are extracted, the strap detaches easily. Position the new strap in the corresponding slots and reinsert the pins, ensuring they are securely fastened. If you lack confidence, consulting a professional watchmaker is always the safest choice.

Straps with a 24mm lug width are fully compatible. Ensure that the thickness of the attachment section is consistent with the case lug dimensions (typically 4-5mm). Artisan leather straps require attention to curvature: if the profile is flat, it might generate a gap between the strap and the lug. Quality manufacturers, such as Casati Milano, create straps with natural curvature that adheres perfectly to the case contours.

Longevity depends on usage intensity, leather quality, and maintenance. Premium alligator or cordovan, with proper care, lasts 4–7 years under intensive daily wear. Vegetable-tanned calf leather typically lasts 3–5 years. Regular maintenance – gentle cleaning, drying after water contact, water-repellent treatments every 6–12 months – significantly extends service life. Bespoke straps crafted by Casati Milano are constructed with sartorial techniques that guarantee 18 months of warranty and superior durability compared to industrial alternatives.
