Strap for Aquis Small Seconds Date 45.5 Stainless Steel / Black / Rubber

The Oris Aquis 01 743 7733 4159-07 4 24 64EB is equipped with a 20mm lug width, the international standard for large diameter watches. This measurement represents the distance between the spring bar pins. Selecting a strap of identical lug width is essential to ensure secure attachment and balanced aesthetics on the wrist.

The 01 743 7733 4159-07 4 24 64EB accommodates multiple solutions: alligator leather with vegetable tanning offers elegance and progressive patina; shell cordovan provides structural rigidity for intensive use; NATO straps deliver versatility and dual mechanical security; vulcanised rubber is ideal for extended diving operations. Your choice depends on use context and personal aesthetic preferences.

Position the watch on a stable, flat surface. Using a spring bar tool, gently press the pins inward toward the case whilst simultaneously sliding the old strap from the lug slot. Insert the new strap (20mm) by aligning it vertically with the pins, then release the spring bar tool to allow the pins to reposition into their seat. Verify the strap is firmly secured on both sides before wearing the watch.

Yes, provided the lug width is precisely 20mm. Milano Straps offers a comprehensive collection of artisanal straps compatible with this reference in leather, NATO, and rubber, each tested for dimensional accuracy before dispatch. Always verify the specific lug width before purchase to avoid mechanical incompatibilities.

An artisanal leather strap—alligator, shell cordovan, or calf—with ordinary use (3–5 days weekly) maintains functionality and aesthetics for 18–36 months. Vegetable tanning develops a progressive patina that enriches the overall appearance. Lifespan varies depending on exposure to moisture, heat, and frequency of wear. Milano Straps recommends periodic rotation with secondary straps to extend useful life and preserve the primary strap's shape.
