Strap for Aquis Date 43 Stainless Steel / Black / Bracelet

The Oris Aquis 01 733 7653 4154-07 8 26 01PEB features a 22mm lug width. This measurement ensures optimal proportion between the 43mm case and the strap, without lateral play. To verify compatibility, measure the internal lug distance with a digital caliper: it should read 22.00mm ± 0.5mm.

There is no universal choice, but three options align with the Aquis's tool-watch heritage: (1) alligator for aesthetic longevity and superior water sealing; (2) NATO in reinforced polyamide for total moisture resistance and zero maintenance; (3) FKM (Viton) rubber for absolute water resistance beyond the certified 300 metres. Selection depends on primary usage and wearing context.

The Aquis features standard straight pins or spring bars with 1.80mm diameter. Position the watch on a stable surface, use a spring bar tool to compress the pin downward, extract it from the lug, then remove the strap. Reverse the procedure to install the new 22mm strap, ensuring the pin sits completely in the lug channel.

Any strap with 22mm lug width is compatible. On Milano Straps you'll find alligator leather, vegetable-tanned calf, NATO grosgrain, and FKM rubber: all tested for precise tolerances and capable of mounting the Aquis case without lateral play. The complete 22mm strap collection is available in the dedicated catalogue.

Lifespan depends on tannage and usage. A vegetable-tanned alligator strap in temperate-dry climate lasts 4–6 years with daily wear. In marine environments or with constant humidity exposure, this reduces to 2–3 years. Vegetable-tanned calf follows similar timelines but develops patina that amplifies aged character. To extend useful life: avoid prolonged immersion, dry after accidental contact, and apply light hydration every 6 months with non-greasy dedicated creams.
