Strap for Oris Big Crown 01 581 7566 4061

The lug width of the 01 581 7566 4061 is 19 mm. This measurement is specific to the Big Crown line and ensures compatibility with 19 mm artisanal watch straps. To verify it, use a digital calliper, measuring the distance between the centre of one lug and the centre of the other, perpendicular to the case.

For the Big Crown 01 581 7566 4061, we recommend cognac alligator or shell cordovan: they emphasise the aviator character and age naturally. If you prefer versatility, vegetable-tanned calf offers balance between luxury and everyday practicality. For a sporty-instrumental approach, NATO or rubber straps preserve the functional identity of the watch.

Remove the lugs securing the strap to the case using a spring bar tool. Position the tool in the dedicated groove, push inward to release the lug, then extract it gently. Thread the new 19 mm strap and reinsert the lug, ensuring it clicks into place properly. If you encounter difficulties, consulting a professional watchmaker is recommended.

Yes, any strap with a 19 mm lug width is compatible with the 01 581 7566 4061 model. High-quality artisanal straps, made from Italian leather, alligator or robust synthetic materials, offer functional and aesthetic alternatives to the original strap while maintaining full mechanical compatibility.

A high-quality vegetable-tanned leather or alligator strap, with periodic maintenance, typically lasts 3–5 years of moderate daily wear. Shell cordovan tends to last longer due to material density. Natural ageing is part of the appeal: the patina that forms increases aesthetic character over time.
