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

The lug width (ansa width) of the Oris Aquis 01 743 7733 4155-07 4 24 69EB is 22mm. This measurement determines compatibility with aftermarket straps. You can verify this dimension with a digital calliper by measuring the internal distance between the spring bar pins.

The ideal strap depends on intended use: for formal contexts, an alligator with vegetable tannin and aged patina delivers elegance without compromising the case's instrumental character. For diving, an FKM (Viton) rubber strap of 1.5-2mm thickness ensures comfort, durability, and full access to the 300-metre water resistance. For daily versatility, shell cordovan with natural grain maintains aesthetic authority with less maintenance than standard calf leather.

The process is straightforward: locate the spring bars—two horizontal metal pins at the strap attachment points. Using a spring bar tool, press gently inward to release the pin from its seat in the case lug, then slide out the old strap to fully extract the pin. Align the new strap with the lug holes, then reinsert the spring bar. Verify both ends are securely anchored before wearing.

Absolutely. The 22mm lug width is a widely standard dimension, compatible with hundreds of quality aftermarket straps. MilanoStraps offers a curated collection of straps in leather, fabric, and rubber specifically selected for this measurement, ranging from Italian artisanal leather to high-performance synthetic options.

Longevity depends on material and usage: alligator or shell cordovan with vegetable tannin lasts 8-15 years with proper maintenance (regular brushing, drying after water contact). Standard calf leather lasts 4-8 years. If you frequently expose the strap to salt water, expect a 30-40% reduction in lifespan. Rubber straps typically last 5-7 years before hardening, regardless of use intensity.
