Strap for Aquis Date 36

The Oris Aquis 01 733 7652 4156-07 4 18 31 features an 18mm lug width, meaning the distance between the spring bars (strap attachment points) is precisely 18 millimetres. This measurement is critical when selecting bespoke leather straps or aftermarket alternatives, as straps are manufactured to exact tolerances and are not interchangeable across different lug widths.

For the 36mm Aquis with 18mm lugs, we recommend three primary options: (1) Alligator leather with vegetable tanning for formal contexts and timeless aesthetic development; (2) Vegetable-tanned calf leather for those who appreciate natural patina formation and unique grain evolution; (3) Ballistic nylon NATO strap for sporting versatility and tool-free quick changes. FKM rubber is ideal for genuine diving conditions or humid environments.

The procedure is straightforward: obtain a spring bar tool (readily available online or from watchmakers); insert the bifurcated tip into the lateral slots beneath the lugs, apply inward pressure to compress the spring, remove the old strap, and insert the new one. Careful technique prevents case scratching. Casati Milano provides complimentary guidance for customers purchasing bespoke straps.

Yes, exclusively 18mm-wide straps are compatible. Spring bar diameters must correspond precisely (typically 1.5mm for 36mm watches). Bespoke straps from milanostraps.it are manufactured specifically for this lug width, ensuring perfect fit and superior longevity through superior construction quality.

A quality leather strap (alligator or vegetable-tanned calf) typically lasts 3-5 years under daily wear conditions, with perspiration and UV exposure accelerating natural aging processes. Longevity extends considerably if the strap is rotated amongst 2-3 alternatives. Deep patination does not indicate deterioration—it represents desirable natural aging of the leather. FKM rubber maintains functional integrity for approximately 10 years if stored in temperature-controlled environments.
