Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7770 4157-07 8 18 05P?

The lug width of this timepiece is 18 millimetres. This measurement represents the internal distance between the two integrated case lugs and is the fundamental parameter for selecting a compatible strap. Verify by measuring the space between the case attachments; do not confuse this measurement with the actual lug diameter.

Which strap is best suited for the Oris Aquis 36.5mm?

For an Aquis of these proportions, we recommend alligator or vegetable-tanned calf leather straps for formal contexts, which maintain elegance without burdening the case. For aquatic use, nylon NATO or FKM rubber guarantee waterproof resilience. Should you desire tactile luxury, shell cordovan develops a unique vitreous patina over time. Choice depends on context and dial colouration.

How do you change the strap on an Oris Aquis with integrated lugs?

The Aquis features a proprietary integrated lug system. Unlike conventional screw-in springbars, this system requires precise manufacturing tolerances. We recommend consulting a qualified watchmaker or contacting Casati Milano directly for professional replacement, ensuring the new strap is specifically crafted for this proprietary geometry.

Is there an aftermarket strap compatible with the 18mm lug width?

Yes, Milano Straps offers a collection of bespoke handcrafted straps in 18mm specifically engineered for watches with integrated lugs. Each strap may be customised in materials (alligator, vegetable-tanned calf, shell cordovan), buckle finishes, and lug profile geometry, guaranteeing structural and aesthetic compatibility with the Aquis.

How long does a natural leather strap last on a daily-wear timepiece?

A natural leather strap subjected to daily wear has an average longevity of 3–5 years, dependent upon frequency of wear, solar exposure, and ambient humidity. Vegetable-tanned leather develops a chronological patina that extends perceived value; shell cordovan, owing to its density, resists degradation longer. Annual inspection and natural wax treatment are recommended to preserve elasticity and longevity.
