Strap for Oris Rectangular 01 583 7657 4061

The lug width is 21 millimetres. This measurement represents the distance between the two horizontal pins on which the strap rests. It is essential to verify this specification before purchasing an aftermarket strap to ensure perfect constructive compatibility.

The best strap depends on use and aesthetic preference. For pure elegance, Mississippi alligator in cognac tone is the premier choice, as its regular grain perfectly dialogues with the rectangular case geometry. Alternatively, shell cordovan represents the pinnacle of durability and organic patina development. For daily versatility, vegetable-tanned calf leather in brown is a reliable and elegant option.

Strap changing requires a spring bar tool, a specific implement with two flat ends that allow you to compress the small springs (spring bars) situated within the lugs. Position the tool on each pin, gently compress the spring, and slide the old strap outward. Repeat the process on the other side. Insert the new strap by aligning one end first, compressing the spring, and securing the other. If you are inexperienced, entrust the task to a professional watchmaker.

Durability varies based on material and usage. A quality alligator or shell cordovan strap, with proper maintenance, lasts 5–8 years under moderate daily wear conditions. A vegetable-tanned calf strap typically lasts 3–5 years. Longevity extends significantly if the watch is not worn daily and if the strap undergoes periodic conditioning with leather-specific creams.

Yes, provided the strap is certified for 21-millimetre lug width and thickness does not exceed 4–5 millimetres. The Rectangular's lugs have a slight inward curve, which enables perfect fit. Always verify that the strap features removable spring bars and that construction quality (stitching, finishes, edge bevelling) is coherent with that of the Swiss watch.
