Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7730 4134-07 5 24 10EB?

The lug width of this model is 24 millimetres. This measurement refers to the distance between the two attachment lugs on the case. Precision is essential, as a 22mm or 26mm strap will not fit correctly.

What is the best strap for the Oris Aquis 01 733 7730 4134-07 5 24 10EB?

Selection depends on intended use. For classical elegance, we recommend alligator or calf leather in vegetable tanning. For aquatic resistance, NATO fabric or FKM rubber are ideal choices. A deployante buckle in stainless steel is recommended for this model due to superior stability in tool watches.

How do you change the strap on an Oris Aquis?

Remove the watch from your wrist and place the case on a stable surface. Use a spring bar tool: insert the small protrusion under the spring bar from one side and gently lift while pushing the bar toward the opposite side. The bar will retract, allowing you to remove the old strap. Repeat for the other side. Align the new strap with the lug holes and reinsert the bars until they click into place.

Which aftermarket straps are compatible with the Oris Aquis 01 733 7730 4134-07 5 24 10EB?

All artisanal straps with 24mm lug width are compatible with this model, provided they meet a tolerance of ±0.5mm. Milanostraps offers a comprehensive collection of straps in vegetable tanned leather, alligator, calf, NATO, and rubber, all verified for structural and aesthetic compatibility.

How long does a leather strap last on a wristwatch like the Oris Aquis?

A natural leather strap with vegetable tanning lasts an average of 3–5 years with daily wear, depending on humidity and sunlight exposure. Alligator tends to last longer due to fibre density. Vegetable tanned leather develops visible patina within the first year, enriching aesthetic appearance. With regular maintenance (gentle cleaning and biannual conditioning), lifespan can be extended.
