Strap for Oris Aquis 01 733 7652 4192

The Oris Aquis 01 733 7652 4192 is equipped with an 18mm lug width. This measurement is determined by the geometry of the 36mm case and defines univocal compatibility with straps specifically engineered for this dimension. To verify it, use a digital calliper and measure the internal distance between the spring bar holes.

For the Aquis 36mm, we recommend three options: first, vegetable-tanned alligator that dialogues subtly with the ceramic bezel insert; second, grey pearl nubuck calf with polished steel deployante, a solution alternating formal elegance and water resistance; third, navy polyamide NATO for those prioritising dive functionality and rapid strap changes. We advise against shell cordovan, as the patina of horse leather competes visually with the case geometry.

Remove the watch from your wrist. Place the case on a soft surface to prevent scratches. Locate the two metal spring bar pins holding the original strap. Using a dedicated spring bar tool, apply pressure to the internal spring, lowering it until the strap detaches. Insert the new 18mm strap by engaging the spring bar into position. Verify symmetry relative to the crown at 10 o'clock.

Yes, any strap featuring an 18mm lug width is compatible, provided the insertion tolerance meets industry standard: the strap must enter the spring bar holes without forcing or excessive looseness. Artisanal straps in vegetable tanning or nubuck maintain a tolerance of ±0.2mm, ensuring smooth engagement and structural security. Always verify that spring bars are stainless steel for marine corrosion resistance.

A vegetable-tanned leather strap (alligator, calf, cordovan) exposed to daily wear and occasional immersion typically lasts 18–24 months before replacement is advisable. Salt water accelerates fibre degradation, though vegetable tanning resists better than modern chemical processes. The patina that develops imparts beauty, though progressively the leather thins. A polyamide NATO strap, conversely, resists degradation for 5–7 years, remaining hydrophobic and structurally intact throughout.
