Strap for Oris Big Crown 01 774 7567 4084

The lug width of the Big Crown 01 774 7567 4084 is 23mm. This dimension represents the internal space between the two lugs of the case, measured from soldering point to soldering point. It is essential to verify this measurement before selecting an aftermarket strap to ensure compatibility and perfect fitting to the case.

For the Big Crown we recommend straps in natural alligator or vegetable-tanned calf leather, which enhance the avionic aesthetic of the watch. Alligator with its characteristic grain amplifies the constructive character, whilst vegetable-tanned calf offers elegant softness. NATO straps in robust cotton also maintain historical heritage, ideal for a sporting approach.

Strap replacement requires the use of a spring bar tool for extraction. Position the tool in the lateral hole of the lug, apply gentle pressure to compress the spring, then remove the old strap. Repeat the operation from the opposite side. For installation of the new strap, insert one spring bar into the hole, slide the strap between the lugs and ensure the spring bar is properly secured in both holes.

Yes, Milano Straps bespoke leather straps are manufactured specifically for the 23mm lug width. We offer premium materials including alligator, vegetable-tanned calf, NATO and FKM rubber. Each strap can be customised according to your colour and finish preferences, guaranteeing perfect fitting to your Big Crown case.

Leather strap durability depends on use and tanning type. A quality vegetable-tanned strap subjected to normal daily wear maintains structural integrity for 3-5 years. With calf or alligator leather, and with careful maintenance (avoiding prolonged moisture and regular cleaning), extended durability can reach 7-10 years. Synthetic NATO straps offer superior resistance, ideal for marine or sporting environments.
