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

The Oris Aquis 01 752 7733 4135-07 4 24 64EB features a 24mm lug width, measured between the spring bars that attach to the case. This dimension is standard across many mid-to-large Oris models and permits compatibility with a wide range of aftermarket straps.

For the 45.5mm Oris Aquis with 24mm lugs, we recommend artisanal leather straps (alligator, vegetable-tanned calf, shell cordovan) for a versatile formal aesthetic, or NATO and rubber straps to preserve the professional tool-watch character. Selection depends on intended use and desired patination.

Use a dedicated spring bar tool or thin flathead screwdriver. Gently press one lateral pin inward to release the old strap, then extract the pin and repeat on the opposite side. Align the new strap with the holes and press the pins until they click into place. Always verify secure closure before wearing the watch.

Yes, aftermarket straps are fully compatible with the Oris Aquis 01 752 7733 4135-07 4 24 64EB. The 24mm lug width is universal and standard spring bars fit perfectly. We recommend artisanal straps to preserve the aesthetic and construction value of the Swiss timepiece.

A quality artisanal leather strap in vegetable tanning or shell cordovan lasts approximately 5–7 years of moderate daily wear. Frequent exposure to water, salt, and humidity reduces longevity: we recommend alternating with NATO or rubber straps in extreme conditions and drying leather immediately after water contact.
