Strap for Superocean Heritage II 46 Stainless Steel / Blue / Silver / Rubber / Folding

The lug width is 24 millimetres. This is the distance between the case attachment points where the strap is fitted. You can verify this easily with a digital calliper by measuring the horizontal distance between the two attachment pins on the case. All compatible straps must respect this measurement exactly to ensure correct fit and visual stability.

There is no universally 'best' strap; the choice depends on use and aesthetic preference. Natural alligator offers elegance and develops patina over time, ideal for formal occasions. French calf emphasises softness and daily comfort. NATO fabric guarantees robustness and rapid drying in marine environments. Vegetable tanning balances beauty, sustainability and moisture resistance. Silicone rubber is the purely functional solution for intensive water activities.

The change requires a specific tool: a spring bar tool (strap removal tool). Position the watch on a soft surface to avoid scratches. Locate the small attachment pins at the ends of the case. Insert the flat tip of the tool into the pin slot, applying light upward pressure to release the internal spring. The pin will slide out. Repeat on the other side, then fit the new strap by aligning the holes with the pins, pressing until you hear a click of closure. Avoid forcing; if the pin does not yield, the case may be scratched.

Durability depends on leather quality, use and maintenance. A premium alligator or calf strap with vegetable tanning can last 5-8 years of moderate daily use. Frequent exposure to salt water, intense perspiration or constant humidity reduces lifespan to 3-5 years. Regular maintenance (cleaning with soft cloth, drying after water contact, occasional application of leather balm) significantly extends longevity. Silicone rubber straps, by comparison, last 7-10 years under any conditions. Casati Milano offers an 18-month warranty on their artisanal straps.
