Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7653 4128-07 4 26 34EB?

The lug width of this model is 26mm, measured centre to centre between the two lateral attachment pins. This is a relatively rare measurement in the aftermarket, requiring straps specifically constructed for this dimension to prevent excessive play during wear.

Which strap is best for the Oris Aquis 01 733 7653 4128-07 4 26 34EB?

Alligator represents the supreme choice, especially in black or chocolate brown, as the natural grain texture dialogues coherently with the ceramic bezel without betraying the tool-watch ethos. Alternatively, Italian calf leather in vegetable tanning develops authentic patina over time. NATO straps in Cordura offer tactical versatility, whilst high-grade FKM rubber maintains the professional profile of the case.

How do I change the strap on an Oris Aquis 01 733 7653 4128-07 4 26 34EB?

Use a spring bar tool (implement with specific hole) to gently push the elastic pin from the inner side of each lug. Once the pin is released, the strap slides away from the case. To install the new strap, align the end on the first lug, insert the elastic pin into the hole, then repeat on the second lug ensuring the pin is fully seated. The operation requires no specialist skill, but precision prevents scratches.

What is the aftermarket strap compatibility for this model?

Any strap with a 26mm lug width is constructively compatible. However, we recommend verifying strap thickness (ideally 3.5-4.5mm) and total length (approximately 245-250mm for both ends combined) to ensure comfortable fastening at the wrist. Milano Straps provides bespoke 26mm straps, tested for manufacturing tolerance precision.

How long does a leather strap last on an Oris Aquis 01 733 7653 4128-07 4 26 34EB?

An artisanal alligator or calf strap lasts 5-8 years with daily use, depending on humidity exposure and maintenance. Leather requires regular aeration (not worn seven days weekly) and gentle cleaning. In vegetable tanning, the strap improves with use by developing patina. If frequently exposed to water (diving, swimming), understand that humidity accelerates ageing; in such cases, a NATO or rubber strap offers greater practical longevity.
