Strap for Aquis Date 36.5 Stainless Steel / White / Bracelet

The Oris Aquis 01 733 7731 4151-07 8 18 05P features a lug width of 20mm. This is a standard construction specification that allows compatibility with an extensive catalogue of artisanal straps. To verify the correct measurement, use a digital calliper positioned perpendicularly between the lug shoulders, excluding the vertical passants of the spring bar.

Strap selection depends on intended use and aesthetic preference. Alligator with natural grain reinforces the formal authority of the ceramic and steel case, ideal for business contexts. Shell cordovan offers predictable ageing and develops patina depth over time. Vegetable-tanned calf provides balance between suppleness and durability. NATO straps in technical textile suit sporting and travel applications, whilst vulcanised rubber restores the Aquis to its diving watch vocation.

The procedure requires a spring bar tool and tactile precision. Position the watch with lugs facing upwards. Insert the spring bar tool into the gap between the lug shoulder and the passant, then gently press inward to release the elastic spring. Withdraw the spring bar from the metal lug shoulder, then repeat the process on the opposite side. Once the original strap is removed, insert the spring bar into the passants of the new 20mm strap following the reverse procedure. Always verify that the spring bar is fully seated in both lug shoulders before wearing the watch.

Yes, all straps equipped with a 20mm lug width are compatible with the Oris Aquis 01 733 7731 4151-07 8 18 05P. Milano Straps offers a specialised catalogue of artisanal straps in this width: alligator, shell cordovan, vegetable-tanned calf, NATO in technical textile, and vulcanised rubber. The standardisation of the 20mm lug width provides access to the broadest and most specialised aftermarket strap market in contemporary watchmaking, significantly amplifying customisation possibilities.

Leather strap longevity depends on tanning method, thickness, and environment of use. An alligator strap with vegetable tanning, worn daily in dry conditions, maintains functional and aesthetic integrity for 3-4 years before showing visible wear. Shell cordovan, being more robust, may last 4-5 years. Vegetable-tanned calf, being more delicate, requires care in humid environments and typically endures 2-3 years under intensive use. Seasonal rotation of straps significantly extends the life of each piece, allowing leather to dry and stabilise between periods of wear.
