Strap for Aquis Date Calibre 400 41.5 Stainless Steel - Yellow Gold / Blue / Rubber

The lug width of the Oris Aquis is 22 millimetres. This measurement is essential for strap compatibility: any 22mm strap will attach correctly to the lugs without mechanical play, ensuring structural soundness and longevity of the attachment points.

The choice depends on intended use: for professional diving, FKM vulcanised rubber guarantees absolute chemical inertness; for formal daily wear, vegetable-tanned Florentine calf with natural patina; for technical-casual versatility, a jacquard or twill NATO strap. Alligator offers aesthetic sophistication without compromise on durability, ideal for those seeking elegance without sacrificing functionality.

Use a quality spring bar removal tool, inserting the flat blade between the lug and strap. Gently prise outward until the lug spring releases. Repeat on the opposite side, then insert the new strap by levering until the spring returns to position. Do not force: movement must be smooth. If unfamiliar with the procedure, consult a specialist watchmaker.

Yes, absolutely. 22mm aftermarket straps are fully compatible. Milanostraps provides a selection of artisanal straps in leather, NATO and rubber specifically dimensioned for this lug width, verified for manufacturing tolerances and material quality, enabling aesthetic personalisation without technical compromise.

A quality, vegetable-tanned leather strap typically lasts 18–36 months of continuous daily wear. Longevity depends on frequency of water immersion, UV exposure, climate humidity and maintenance. Tuscan leather well-cared-for and occasionally treated with natural wax can develop noble patina for 5–7 years. FKM rubber remains chemically stable without apparent ageing, maintaining elasticity for 4–8 years.
