Strap for Oris Rectangular 01 561 7621 4961

The lug width (misura ansa) of the Oris Rectangular 01 561 7621 4961 is 16mm. This is the distance between the upper and lower lugs where the strap attaches to the case. To verify it, insert a ruler or calliper exactly where the strap connects. Choosing a strap with this precise measurement ensures balanced aesthetics and correct structural tension on the wrist.

For this Art Déco model, we recommend three options: genuine alligator for a vintage effect that improves with patina; vegetable-tanned calf for softness that counterbalances the case's geometric rigidity; NATO fabric in neutral colours (black, grey, blue) for a contemporary, versatile approach. The choice depends on context: formal and daily for alligator, elegant-detached for calf, sport-chic for NATO.

The replacement occurs via the spring bars that connect the strap to the case lugs. Position the watch on a soft surface, locate the small elastic pin at the bottom of each lug, and push gently inward to release the previous strap. Insert the new 16mm strap at the same points, ensuring the pins snap correctly. If unsure, consult a specialised artisan.

No. An aftermarket strap of quality with 16mm lug width is entirely compatible. Many artisans produce straps built to standards superior to official replacements, using premium materials like alligator, shell cordovan, and vegetable-tanned leather. Compatibility depends solely on lug width and thickness, not the strap brand.

A genuine leather strap (alligator, calf, cordovan) has a useful life of 2-4 years under normal daily wear. Exposure to sweat, water, and sunlight accelerates ageing. Vegetable-tanned leather ages more elegantly than chromium-tanned, developing a patina that many connoisseurs consider an asset. Regular maintenance (cleaning every 3 months, conditioning with neutral creams) significantly extends durability.
