Strap for Aquis Date 41.5 Stainless Steel / Blue / Rubber

The lug width of the Oris Aquis 01 733 7766 4135-07 4 22 64FC is 22mm. This measurement represents the distance between the lug attachment points on the case and determines compatibility with aftermarket straps. To verify, measure with a digital calliper between the two mounting holes: the value must be exactly 22mm.

Strap choice depends on intended usage. For daily elegance, vegetable-tanned leather such as Tuscan Testa di Moro is recommended: it ages naturally, developing a unique patina. For extreme performance in marine environments, FKM rubber is unsurpassed: it resists salt water and requires no maintenance. NATO straps offer chromatic versatility and rapid change without tools. For the collector, dyed alligator leather provides refinement and superior humidity resistance.

The process is straightforward and requires no specialist tools. Place the watch on a soft surface (cloth) with the dial facing downwards. Locate the spring bars (spring-loaded pins) that secure the strap to the lugs. Using a spring bar tool or even the flat end of a small screwdriver, press inward one end of the bar until it disengages from its seat, then remove the strap. Repeat on the other side. Insert the new 22mm strap into the first lug by pushing the spring bar until it engages. Verify that the strap holes align perfectly with the case holes.

Yes, completely compatible. Milano Straps offers a curated selection of artisanal 22mm straps in multiple materials: Italian vegetable-tanned leather, shell cordovan, NATO fabrics, vulcanised rubber. All are manufactured to high quality standards and guarantee total mechanical compatibility. Before purchasing, always verify that the strap is explicitly certified for 22mm.

Leather strap lifespan depends on tanning method, frequency of use, and humidity exposure. A quality vegetable-tanned leather strap, used under normal conditions (not daily in water), provides 4-6 years before showing significant structural wear. Regular exposure to salt water considerably shortens this lifespan. For those who intend to use the diver frequently in humid environments, we recommend alternating the leather strap with a rubber one, extending its life. Light maintenance (quick drying after water contact) significantly improves durability.
