Strap for Aquis Date 43.5 Stainless Steel / Matte Black / Rubber

The lug width of the Oris Aquis 01 733 7730 4124-07 4 24 64EB is 24mm. This measurement represents the distance between the lugs on the watch case. To verify, use a digital calliper or flexible tape measure placed directly on the lugs: the result must be precisely 24.0mm. This dimension falls within the professional range typical of modern diving instrument watches and accommodates high-quality structured straps.

For diving, we recommend FKM rubber or NATO in high-density synthetic fabrics. Rubber is waterproof, sweat-resistant, unaffected by chlorine and saltwater, with excellent grip on wet wrists. NATO allows rapid adjustment without tools, essential if you need to change straps during aquatic activities. Leather options such as alligator or calf, whilst aesthetically refined, require post-immersion drying and do not offer the same operational ease.

To change the strap, use a spring bar removal tool. Insert the fork of the tool into the lateral gaps of the case, compress the internal spring of the pin and slide the pin out of the lug. Remove the original strap. Insert the new strap's pin into the upper lug, compress slightly and push the pin into the lower lug until you hear a click. Repeat on the other side. The entire procedure takes less than three minutes.

Yes, any strap with a 24mm lug width is compatible with the Oris Aquis 01 733 7730 4124-07 4 24 64EB. The pins are standard and removable. Verify that the strap is constructed for 24mm lugs (not 22mm or 26mm) and offers adequate thickness for the 43.5mm case weight. Artisanal straps in alligator, shell cordovan, vegetable-tanned calf or regenerated NATO are all valid options.

A quality leather strap (alligator, calf, shell cordovan) on an Oris Aquis 24mm lug width will last approximately 3–5 years with regular use. Longevity depends on exposure to perspiration, sunlight and humidity. Vegetable-tanned leather straps age elegantly and can be rejuvenated through drying and treatment with natural oils. If you wear the Aquis primarily for diving, choose rubber or NATO: they resist saltwater and chlorine indefinitely, eliminating the degradation factor.
