Strap for Aquis Date 43.5 Relief Stainless Steel / Grey / Rubber

The Oris Aquis 01 733 7730 4153-07 4 24 66EB features a 24mm lug width. This dimension is standard for this model and must be strictly observed when selecting aftermarket bracelets and straps. To measure the lug width accurately, position a digital calliper perpendicular to the distance between the two lugs (case horns), which will provide the exact measurement in millimetres.

Your choice depends on intended use. For frequent diving, we recommend FKM (Viton) rubber straps for absolute chemical inertness in saltwater environments, or ripstop nylon NATO straps for rapid underwater changes. For a more refined appearance whilst maintaining technical capability, alligator leather with vegetable tanning develops character over time. For hybrid formal-diving configurations, burgundy shell cordovan with hand-stitching offers structural robustness and elevates overall aesthetics.

The Oris Aquis is fitted with straight lugs, compatible with standard 24mm spring bars. Procedure: remove the old strap using a dedicated spring bar tool positioned beneath the spring bar; carefully extract the spring bar from its seats; align the new strap holes with the lugs; push the spring bar back into position until it clicks. We recommend working under side-lighting to verify correct positioning. Milano Straps provides step-by-step instructions for each strap type.

All Milano Straps featuring 24mm lug width are compatible with this model. Our range includes: alligator and shell cordovan leather straps with vegetable tanning, NATO webbing in various weights, medical-grade FKM rubber straps, and Horween leather options. Each strap is tested for perfect fit on standard 24mm lugs. We recommend browsing our '24mm straps' category online for comprehensive availability.

Durability depends on actual usage and material selection. Vegetable-tanned alligator, when frequently exposed to saltwater, requires immediate drying and regular maintenance (hydrophobic balms), lasting 3–5 years with frequent diving. Shell cordovan, denser and naturally oilier, offers superior resistance (5–7 years). For intensive diving use, we recommend FKM rubber straps, given their chemical stability and virtually unlimited durability. However, no leather strap replaces the waterproof assurance of a metal bracelet during regular technical diving operations.
