Strap for Aquis Date Diamonds 36.5 Stainless Steel / Blue - Diamond / Rubber

The lug width is 18mm. This dimension is specific to this model and corresponds to the distance between the spring bars that attach the strap to the case. It is not compatible with 20mm or 22mm straps. To verify compatibility with an aftermarket strap, measure the width of the original lug using a digital calliper.

For this model, we recommend Tuscan leather straps with vegetable tanning for daily and evening wear, alligator or shell cordovan for more formal occasions, or polyamide NATO and FKM rubber straps for sports use and diving. Your choice depends on your lifestyle: if you alternate office work and diving, consider a leather strap that develops natural patina over time.

Changing the strap is straightforward: use a spring bar removal tool (available online) to press the pins that hold the strap to the case lugs. Gently remove the original strap, then insert the new strap by aligning the holes with the lug and pressing the pins until they click into place. Always verify that the strap is securely fastened before wearing the watch.

Yes, it is fully compatible provided the strap is specifically manufactured for 18mm lug width. Before purchasing, verify that the widths match exactly: 18mm. Quality straps made from Tuscan vegetable-tanned leather, alligator, or synthetic materials such as FKM rubber will ensure a perfect fit and durability comparable to the original.

A high-quality Tuscan vegetable-tanned leather strap can last 5–10 years with moderate daily wear, developing a natural patina that increases aesthetic appeal over time. Longevity depends on exposure to humidity, direct sunlight, and cleaning frequency. Avoid exposing leather straps to prolonged immersion if made from hide; for frequent diving, opt for FKM rubber or synthetic NATO straps that maintain structural integrity even in salt water.
