Strap for Rectangular Complication Stainless Steel / Silver - Arabic

The Oris Rectangular features a lug width of 22mm, a precise dimension positioned between the standard 20mm and 24mm specifications. This width is determined by the exact distance between the two attachment lugs of the rectangular case. To verify compatibility with an aftermarket strap, a digital calliper should be used to measure the internal passant: it must be precisely 22mm. A narrower strap (20mm) would result in excessive play, whilst a wider one (24mm) would not fit into the lugs.

The Oris Rectangular accommodates multiple strap choices, depending on intended use and aesthetic preference. Genuine alligator emphasises the vintage-modern character of the rectangular case, with a scale texture that amplifies sophistication perception. Vegetable-tanned calf offers a sartorial profile with patina evolving towards caramel hues. NATO in canvas or nylon (dark blue, anthracite grey, black) imparts field-ready versatility. FKM rubber with fine grain maintains elegance during humid or aquatic environments. Selection depends on which personality you wish to emphasise: classical, vintage, sporting, or minimalist.

Strap replacement requires a spring bar tool, a specialised fork-shaped instrument that gently lifts the small pin (spring bar) securing the strap to the case lugs. Procedure: position the spring bar tool at one side of the strap, lift gently to create space between the lug and strap, then extract the strap end. Repeat on the other side. Insert the new strap by sliding the pin into the groove, then ensure both sides are firmly secured. The 22mm lug width guarantees that the passants of the new strap align perfectly with the rectangular lugs.

An original Oris strap, supplied directly from the Swiss manufacture, assures construction compliance and controlled quality matching case specifications. Artisanal aftermarket straps—such as those crafted by Casati Milano—offer design creativity and leather selection often superior, thanks to specialised suppliers (French alligator, Japanese cordovan, European calf). Compatibility with 22mm is guaranteed if the passant has been measured and constructed with millimetre precision. The substantial difference lies in customisation capacity: an artisanal strap permits colour, thickness, and stitching choices according to preferences the original does not offer.

Leather strap longevity depends on material, frequency of use, and care. Vegetable-tanned calf, subjected to daily wear in temperate climates, maintains structural integrity for 3-5 years before replacement becomes necessary. Quality alligator can last 5-7 years, benefiting from greater scale resilience. NATO canvas can exceed 10 years of service. FKM rubber maintains elastic properties for approximately 5-6 years. To extend strap lifespan, recommend regular cleaning with soft-bristled brush and occasional application of specific oil (not universal grease). Store the watch in a dry location: excessive humidity accelerates degradation even of the noblest vegetable-tanned leather.
