The Aquis 01 733 7653 4128-07 4 26 32EB, seen from the bench

The Oris Aquis 01 733 7653 4128-07 4 26 32EB is a professional dive instrument from independent Swiss manufacture. It features a stainless steel case of 43 mm diameter, unidirectional ceramic bezel, anti-reflective sapphire crystal, and a 26 mm lug width. The Oris caliber 733 movement, based on ETA and finished to Oris standards, oscillates at 28,800 vibrations per hour and includes manual winding cylinders with date window at 3 o'clock. Water-resistant to 300 meters, the screw-down crown and ceramic insert ensure corrosion resistance and long-term reliability.

Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7653 4128-07 4 26 32EB?

The lug width is 26 millimetres. This measurement is not a commercial standard: it is the result of specific case proportions—43 mm diameter—and the geometric constraints of the attachment pins. To measure the lug width accurately, place a ruler between the inner case lugs at their widest point and verify the distance. A measurement error of just a few millimetres compromises biomechanical fit and creates gaps between lug and wrist.

Which strap is most suitable for the Aquis 01 733 7653 4128-07 4 26 32EB?

The choice depends on actual usage patterns. For diving, an FKM or neoprene rubber strap is the most reliable solution: it adheres securely to a wet wrist and resists saltwater degradation. For daily wear, a vegetable-tanned leather in natural or dark brown creates elegant contrast with the ceramic bezel. NATO straps in stabilised textile offer functional compromise between aquatic and everyday contexts. Shell cordovan is reserved for owners who maintain the Aquis as a formal wrist watch in dry environments.

How do you replace the strap on the Oris Aquis 01 733 7653 4128-07 4 26 32EB?

The Aquis uses a simple spring bar attachment system: a spring bar tool (or small lever) is required. Position the tool beneath the bar, apply gentle vertical pressure until the internal spring releases, and the bar slides out easily. Align the new 26 mm lug with the case pin and insert. The operation takes approximately 5 minutes for experienced users. Milano Straps provides detailed instructions with every strap ordered.

Are aftermarket 26mm straps compatible with this Aquis?

Yes, any strap with 26 mm lug width is fully compatible. Milano Straps offers a handcrafted selection of leather, alligator, calf, rubber and NATO straps in the specific 26 mm width for models such as the Aquis. Compatibility is guaranteed by lug geometry and the distance between attachment pins. Straps are supplied with either universal or watch-specific spring bars, depending on your requirements at order time.

What is the expected lifespan of a leather strap on the Oris Aquis 01 733 7653 4128-07 4 26 32EB?

A vegetable-tanned leather strap of artisanal quality typically lasts 3–5 years with regular daily wear, provided it is not subjected to frequent saltwater or prolonged humidity exposure. Shell cordovan straps can endure 7–10 years in dry environments. FKM rubber straps offer superior longevity, up to 8–12 years, with the advantage of no degradation from aquatic exposure. Lifespan depends on wearing frequency, maintenance (periodic cleaning with a dry cloth) and environmental conditions. Milano Straps offers regeneration and repair services for worn straps.
