The Aquis 01 733 7652 4991-07 8 18 01P, seen from the bench

The Oris Aquis 01 733 7652 4991-07 8 18 01P is a refined interpretation of the Aquis philosophy: a diving instrument with absolute reliability housed in a 36-millimetre stainless steel case. The unidirectional scalloped bezel and 300-metre water resistance demonstrate that compact dimensions do not compromise technical functionality. The automatic Oris 733 calibre movement features hours, minutes, seconds, and date window. Lug width is 18 mm.

Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7652 4991-07 8 18 01P?

The lug width of this model is precisely 18 millimetres. This dimension is determined by the exact distance between the two lug pins on the 36mm case. It is essential to respect this measurement when purchasing an aftermarket strap to ensure a perfect fit and the absence of disproportionate spring bars.

Which strap is recommended for the Oris Aquis 36mm?

For a timepiece of this elegance and versatility, we recommend a strap in African alligator or vegetable-tanned calf leather. Alligator delivers a formal finish and a patina that ages beautifully over time. Calf leather offers equilibrium between aesthetics and practicality. For more sporting uses, a NATO strap in Jacquard fabric is the ideal technical choice.

How do I change the strap on the Oris Aquis 01 733 7652 4991-07 8 18 01P?

To change the strap, you must remove the two lug pins using a dedicated tool (spring bar tool). Position the tool in the notch of the pin, apply light lateral pressure until the lug is freed, then extract the old strap. Insert the new 18mm strap into the pins and verify that they snap firmly into their housings. The procedure takes less than a minute with practice.

Can I use an aftermarket strap compatible with this lug width?

Absolutely. Any strap with an 18mm lug width is compatible with your Aquis 36. The artisan straps from Milano Straps, crafted in premium materials such as alligator, shell cordovan and vegetable-tanned leather, fit perfectly on this case. We recommend always verifying the lug width (18mm) at the moment of order.

How long does a leather strap last on a watch like this Aquis?

Durability depends on the material chosen and its use. A high-quality African alligator strap can last 5–8 years with ordinary maintenance (periodic cleaning, drying after water contact). Vegetable-tanned leather tends to last 3–5 years before showing significant signs of wear. NATO straps in fabric are practically indestructible and can last 10+ years. The patina that develops on leather and alligator is considered a virtue, not a flaw.
