Strap for Aquis Date 36.5 Upcycle

The lug width (ansa width) of the Oris Aquis 01 733 7770 4150-Set is 18.00mm. This dimension is the standard for 36mm watches and is compatible with a wide selection of artisanal straps: calf leather, alligator, shell cordovan, NATO, rubber. To verify compatibility, measure the distance between the metal pins of the lugs: it must be exactly 18mm.

The choice depends on your use case and aesthetic preferences. For a formal look, shell cordovan with vegetable tanning develops patina and ages beautifully. For actual diving use, fluoro-elastomeric rubber guarantees chemical and antimicrobial resistance. Natural alligator is the discrete luxury solution, while a NATO strap in canvas ensures practicality and spare parts availability. Consider the dial colour: a navy blue pairs naturally with warm brown calf, a black dial favours burgundy shell cordovan or glossy black calf.

The procedure is straightforward and requires no specialised tools. With a small flathead screwdriver (ideally 1.5mm), remove the strap pin from the non-buckle side, resting the watch on a soft surface. The pin will slide out and the strap will detach. Insert the new strap pin (ensuring it is 18mm compatible), align it with the hole and press until you hear a small click. Repeat on the other side.

Absolutely. Thanks to the widespread adoption of the 18mm standard, your Aquis is one of the most versatile models for accepting aftermarket artisanal straps. The key is to verify that the strap is designed to accommodate 18mm pins and that the quality of the leather (or rubber) is consistent with the manufacturing standard of the watch. An artisanal Italian strap, made with natural tannins and bespoke finishes, transforms the wearing experience of the Aquis.

Durability depends on the material and intensity of use. A mid-to-high quality calf strap lasts 3–5 years if worn daily, but deteriorates significantly if exposed to water, perspiration and UV rays without protection. Shell cordovan, being denser and more compact, can last 7–10 years while maintaining visible beauty. If you use your Aquis in frequent aquatic environments, an FKM rubber strap is the most durable choice (10–15 years without compromise). A deployante clasp in steel protects the strap from localised wear at the lugs.
