Strap for Big Crown Small Second Pointer Day Stainless Steel / Black / Bracelet

The lug width of reference 01 745 7629 4064-07 8 22 76 is precisely 22 mm. This width is proportionate to the 44 mm case diameter and ensures visual balance between the lugs and the overall structure. Any strap with a 22 mm lug width is fully compatible with this model.

The choice depends on use and context. For formal elegance, we recommend shell cordovan with vegetable tanning or glossy black alligator: both develop noble patina over time. For daily wear and versatility, a NATO in grey or navy cotton offers waterproofing and tool-free changes. For diving or humid environments, FKM rubber ensures durability and moisture resistance without compromise.

Position the watch on a cork pad with the lugs facing upward. Locate the spring bar under each lug and use a dedicated tool to compress the internal spring. Once depressurised, the bar slides out of its seat, allowing removal of the old strap. Insert the new strap by aligning the lug holes with the bars and press until you hear a light click of engagement. If inexperienced, consult a professional to avoid damage.

Yes, any strap with a 22 mm lug width is compatible. Quality aftermarket straps in leather, NATO or rubber pair seamlessly with the Oris case. The key is verifying exact lug width and choosing durable materials such as full-grain leather, vegetable-tanned cordovan or technical rubber to ensure comfort and longevity.

A quality leather strap (cordovan, alligator or full-grain calf with vegetable tanning) typically lasts 3–5 years under normal use conditions, with visible wear appearing after 18–24 months in the form of light creasing and natural patina. Longevity increases if you keep the leather dry, avoid prolonged exposure to sunlight and chlorine, and regularly apply protective balms. Very humid environments or frequent diving reduces lifespan: in these cases, FKM rubber remains the most rational choice.
