Strap for Oris Big Crown 01 594 7680 4061

The lug width of the Big Crown 01 594 7680 4061 is 14mm. This measurement refers to the internal space between the two metal pins that connect the case to the strap. To verify strap compatibility, measure this value precisely using a digital calliper, positioning it perpendicularly between the two lug shoulders.

The choice depends on intended use. For collectors who favour discreet elegance, natural alligator or vegetable-tanned calf leather represent ideal solutions, as they age whilst developing patina that complements the satin-finished steel case. For those seeking practicality without aesthetic compromise, a NATO strap in Cordura canvas maintains the watch's historic avionic identity. Vulcanised rubber is recommended for demanding daily use.

The strap is removed using a dedicated tool (spring bar tool) to release the elastic pins fastening the lugs to the case. Position the tool in the small slot at the base of each pin, push gently to compress the internal spring, then extract the pin. Reverse the process to install the new strap, ensuring the pins click firmly into position.

All straps with 14mm lug width are compatible with this model. Milanostraps.it offers a dedicated selection including full-grain leather, alligator, shell cordovan, vegetable-tanned calf, NATO fabrics, and vulcanised rubbers. It is advisable to verify that the lug thickness is coherent with the watch's style, maintaining balanced proportions.

Durability depends on leather quality and intensity of use. An alligator or full-grain calf strap can last 5-10 years with proper maintenance (regular cleaning with damp cloth, correct drying, light conditioning). Leather ages naturally, developing surface creasing that forms part of its character. Replace the strap when creasing becomes structural or when material loses elasticity. Moderate use (3-4 days weekly) significantly extends longevity.
