Frequently asked questions

What is the exact lug width of the Oris Aquis 01 733 7731 4191?

The lug width of the Oris Aquis 01 733 7731 4191 is 19 millimetres. This measurement is taken from the centre of one lug hole to the centre of the other, excluding any case shoulder ornamentation. Precise measurement is essential to ensure the strap fits correctly without excessive play or slippage risk.

Which strap pairs best with the Oris Aquis 01 733 7731 4191?

The ideal strap depends on your intended use: a vegetable-tanned Italian calf leather in warm brown maintains daily versatility; a nylon NATO woven strap emphasises the diving tool DNA; a rubber strap is the choice for aquatic environments without compromise; shell cordovan offers authenticity and accelerated patina for those who appreciate premium leather. The Oris Aquis, by virtue of its proportions and design, accommodates every category without aesthetic compromise.

How do I change the strap on the Oris Aquis 01 733 7731 4191?

The change requires a specific tool (spring bar tool) or expert intervention. Position the watch on a soft surface, locate the spring bar holes, push them inward with the tool until the old strap is freed, remove the strap carefully. Insert the new strap by aligning the holes correctly, compress the springs until they click into place. If uncertain, consult a service centre to avoid scratching the case.

Can I use an aftermarket strap on the Oris Aquis 01 733 7731 4191?

Yes, absolutely. Any quality strap with a 19 millimetre lug width is compatible. The artisanal market offers leather, NATO, rubber, and even metal solutions that often surpass the original strap in character and durability. We only advise against bespoke thickness reductions, which compromise the proportion between case and strap.

How long does a leather strap last on the Oris Aquis 01 733 7731 4191?

A quality vegetable-tanned leather strap lasts between 3 and 7 years with daily use, depending on exposure to water, perspiration and environmental agents. Shell cordovan tends to last longer due to the natural density of the material. Lengthening is natural: leather lives and adapts to your wrist. When the strap loses structural integrity (cracks, deep striations), it is time to move to a new strap.
