Strap for Aquis Small Seconds Date 46 Stainless Steel / Blue / Rubber

The lug width (ansa width) of the Oris Aquis 01 743 7673 4135-07 4 26 34EB is 22mm. This measurement is crucial for purchasing a compatible strap. It is measured from the inner shoulder of the left lug to the inner shoulder of the right lug, passing across the case bottom. A strap with non-conforming lug width (even 1-2mm variance) will not mechanically fit the case.

The 46mm Aquis accepts multiple interpretations. Black or dark brown alligator enhances formal legibility and develops patina over time. Vegetable-tanned calf offers sustainability and uniform texture. Ballistic nylon NATO provides maximum reversibility and practicality. Natural vulcanised rubber claims direct sporting and nautical dimension. The choice depends on predominant use and the wearer's aesthetic sensibility.

The replacement is straightforward. Locate the two lug pins (spring bars) positioned beneath the case, one per lug. Using a dedicated tool (spring bar tool) or small lever, compress the spring of the pin, sliding the old strap laterally out of the lugs. The new 22mm strap is inserted by aligning the lug hole to the pins and allowing the spring to lock them in position. Professional watchmaking intervention is not necessary for this routine operation.

Yes. Milanostraps.it offers a complete collection of artisanal straps in 22mm lug width, crafted in premium leather (alligator, vegetable-tanned calf), NATO, and rubber. Each strap is bespoke-configured according to the 46mm Aquis specification. The Casati Milano atelier furthermore proposes custom work and personalised finishing upon commission.

A high-quality leather strap, properly maintained (dried after water exposure, protected from direct heat), has a useful life of 3–5 years, often longer if wear is occasional. Natural leather, unlike synthetic materials, develops patina and character over time, becoming part of the watch's visual history. Periodic strap renewal is not only a functional necessity but an opportunity for aesthetic refresh.
