Strap for Aquis Big Day Date 45.5 Stainless Steel / Blue / Rubber

The lug width (distance between attachment lugs) of the Oris Aquis 01 752 7733 4135-07 4 24 65EB is 24mm. This measurement determines which straps are compatible with your watch. Always measure your own watch perpendicular to the lugs using a digital calliper, excluding any side loops or passants.

The Aquis, being a professional tool watch, pairs exceptionally well with vegetable-tanned leather (calfskin or alligator), NATO straps, or rubber. For elegance with natural patina development, choose cognac, black, or dark grey leather. For sports or water-intensive use, a natural rubber or NATO canvas strap offers practical durability and water resistance. The 24mm lug width permits considerable strap variety and aesthetic flexibility.

To change the strap on a 24mm watch like the Oris Aquis, use a spring bar tool: insert the flat tip beneath the lug pin on the side opposite your desired direction, compress the spring, and slide the pin free. Repeat on the opposite lug. Insert the new strap's pins into the watch lugs, ensure they are fully seated, and verify alignment before wearing.

Yes, absolutely. Any strap with a 24mm lug width is compatible with the Oris Aquis 01 752 7733 4135-07 4 24 65EB, whether from the aftermarket or bespoke artisan workshops like Casati Milano. Verify the lug width is precisely 24mm (not 22mm or 26mm) and that the spring bar and any buckle are constructed to reliable standards.

Strap longevity depends on tanning method and usage patterns. Vegetable-tanned leather of quality, worn daily, typically lasts 2–4 years before creasing or cracking occurs. Chrome-tanned leather extends this to 3–5 years but sacrifices natural patina development. Frequent fresh-water contact shortens lifespan. A premium rubber strap retains elasticity and appearance for 4–6 years under regular use, with superior water and chemical resistance.
