Strap for Aquis Date 36 Stainless Steel / MOP / Rubber

The lug width of the Oris Aquis 01 733 7652 4151-07 4 18 31 is 18 mm. This measurement represents the internal distance between the lugs on the case and is the fundamental parameter for selecting a compatible strap. Always verify that your strap has exactly 18 mm width at the insertion end, as incorrect dimensions will cause mechanical instability and potential damage to the spring bar pins.

The ideal strap depends on intended use. For diving, an FKM rubber strap or water-resistant NATO ensures absolute reliability and maintenance-free operation. For daily elegant wear, an alligator with vegetable tanning or supple calf leather develops fascinating patina over time. For versatility, a blonde calf leather with satin deployante balances the watch's tool-watch character while maintaining aesthetic refinement without sacrificing comfort.

Strap replacement requires a dedicated spring bar tool. Position the watch with the lugs facing upward, insert the thin blade of the spring bar tool beneath the spring pin from the opposite side of the lug you wish to remove. Apply gentle pressure to compress the spring, then slide the pin out from the lug. Repeat on the other side. When installing the new strap, align the holes and insert the pin: the spring will reposition itself automatically when the tip re-enters its seat.

Yes, any artisanal strap with an actual 18 mm lug width is perfectly compatible. Verify that the seller specifies "18 mm lug width" and that the supplied spring bars have the correct thickness (typically 1.2 mm). An aftermarket strap from an Italian craftsman often offers superior quality compared to original straps, thanks to carefully selected leathers and personalised finishing options tailored to your watch's aesthetic.

Durability depends on material and usage patterns. An alligator strap with vegetable tanning, with regular maintenance (monthly cleaning and quarterly conditioning), lasts 2–3 years of daily wear. A more robust calf leather can reach 3–4 years. On a diver like the Aquis, subject to frequent water exposure, we recommend alternating leather and rubber straps, or choosing synthetic material or leather with enhanced water-repellent treatment from the outset. The patina that develops is part of the value: each mark tells the story of real-world use of this tool.
