The Oris Aquis 01 733 7652 4135-07 4 18 34 is a 36mm stainless steel dive watch with 300 meters water resistance, powered by the Oris caliber 733 movement.

Sapphire crystal with internal anti-reflective coating and satin-finished steel case deliver Swiss engineering without excess.

Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7652 4135-07 4 18 34?

The lug width is 20mm. This standard allows the attachment of aftermarket straps specific to this category of medium-sized sport watches. It is essential to verify not only the width but also the thickness of the strap: this Aquis accommodates straps up to 4.5mm without creating visual misalignment.

Which strap is best suited for an Oris Aquis with 20mm lugs?

It depends on intended use. For professional contexts, we recommend matte or polished alligator in medium brown tone, which contrasts elegantly with the satinised steel case. For active diving use, a nylon rally NATO guarantees reliability with wet hands. For refined daily wear, vegetable-tanned leather develops natural patina over time, creating a genuinely personalised object.

How do you change the strap on a watch with 20mm lugs?

The procedure requires specific tools: a quality spring bar tool is essential. Insert the tip into the lateral slot of the lug, compressing the internal spring to free the pin. For 20mm straps, work with gentle movement, as the narrow lug does not tolerate forcing. On a satinised steel Aquis, any careless movement leaves permanent marks.

Are 20mm aftermarket straps compatible with the Oris Aquis 01 733 7652 4135-07 4 18 34?

Yes, provided they meet technical specifications: 20mm width (±0.2mm), maximum thickness 4.5mm, and straight non-articulated lugs. The Aquis does not accommodate straps with hinged bars. Milano Straps provides handcrafted straps verified for mechanical and aesthetic compatibility, eliminating the risk of case micro-abrasions.

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

Durability depends on tanning and usage. Vegetable-tanned calf leather, with moderate water exposure (not constant immersion), lasts 3-5 years with visible but gradual wear, developing characteristic patina. Shell Cordovan resists 8-10 years. Alligator deteriorates in 2-4 years in intense saltwater environment. NATO and rubber straps exceed a decade in any condition. There is no 'absolute best durability': durability exists relative to desired aesthetics.
