Strap for Big Crown Timer Stainless Steel / Black

The lug width of this Oris model is precisely 22 millimetres. This is a standard dimension that ensures broad strap compatibility, from leather options to technical NATO materials and structured FKM rubbers.

There is no universal choice. For formal elegance, we recommend alligator with vegetable tanning in cognac tones; for tactical robustness, a made-in-Italy NATO navy blue or FKM butadiene rubber; for timeless patina development, shell cordovan is unmatched.

The Big Crown 01 735 7660 4064-07 5 22 78 features removable lugs secured by spring bars. To change the strap, use a professional spring bar tool or consult an atelier: gently remove the bars, extract the old strap, and fit the new one, ensuring both spring bars click securely into their seats.

Yes. Any strap with a 22mm lug width is compatible. Milano Straps offers a curated selection of handcrafted vegetable-tanned leather straps, made-in-Italy NATO straps, and technical rubber options, specifically designed for this width and tested on chronographs of this category.

Durability depends on the tanning type and usage. Vegetable-tanned calf resists 4–7 years of daily wear; alligator 5–8 years; shell cordovan beyond 10 years. Rubber and synthetic NATO are virtually indestructible, but require regular cleaning to maintain aesthetics.
