Strap for Big Crown 1917 Limited Edition

The lug width (misura ansa) of the Oris Big Crown 01 732 7736 4081-Set LS is 20 millimetres. This measurement is determined by the internal distance between the two lugs of the case and is essential for ensuring correct fit of any aftermarket strap. Measure precisely at the points where the strap sits when worn.

For the Big Crown 01 732 7736 4081-Set LS, we recommend artisanal leather straps with vegetable tanning, particularly alligator or shell cordovan. These materials enhance the stainless steel case and oversized crown without visual competition. For an authentic aviator or sporting interpretation, technical fabric NATO straps preserve the historical identity of the model. Rubber is ideal for humid environments or water sports.

Strap removal involves removing the spring bars connecting the strap to the case lugs. Use a dedicated tool or small lever to depress the elastic pin, allowing the bar to slide free. Once the strap ends are released, align the new strap holes with the lugs and reinsert the spring bars until fully seated. This process requires care to avoid scratching the case.

Any artisanal quality strap with 20mm lug width is compatible with the Oris Big Crown 01 732 7736 4081-Set LS. Milano Straps offers a specialised collection of 20mm straps in leather (alligator, calf, shell cordovan), NATO fabrics and technical rubber, all tested for dimensional compatibility. Construction quality guarantees multiple pairings over time without premature wear.

An artisanal leather strap with vegetable tanning, worn daily, maintains full function and aesthetic appearance for 3-5 years before showing significant wear signs. Longevity varies based on environment (humidity, heat, sun exposure) and frequency of use. With proper care (drying after water contact, storage in dry conditions), ageing becomes elegant: patina develops naturally, adding aesthetic character rather than degrading the product. NATO and rubber straps offer greater longevity in extreme conditions.
