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

The lug width of this model is 24mm, a standard specification that accommodates straps specifically designed for this width. The space between the two case lugs measures precisely 24mm, perpendicular to the watch body. This calibre ensures a snug fit without excessive play.

For a timepiece of this magnitude, we recommend vegetable-tanned alligator – it maintains the sporting function without compromising case quality. Alternatively, stiff calf leather (Tuscany grain) offers robustness and rapid drying; for frequent aquatic use, FKM rubber (technical elastomer) resists chlorine and saltwater degradation. NATO nylon straps remain ideal for quick replacement and practicality.

The Oris Aquis 01 743 7733 4135-07 4 24 64EB features standard lugs: using a spring bar tool or small flat screwdriver, gently release the small spring underneath the lug by pushing in the opposite direction. Remove the old strap and insert the new 24mm strap, ensuring the spring correctly re-seats into the lateral holes of the lug.

Yes. Any strap with 24mm lugs is compatible with this model. Milano Straps offers a specific range of 24mm straps in leather, alligator, vegetable-tanned calf, NATO, and technical rubber – all tested for this watch's lug width. Compatibility is guaranteed by standard construction specifications of the baionette attachment.

Leather strap longevity depends on usage and maintenance. Quality alligator or calf can last 3–5 years with moderate daily wear; with frequent exposure to salt, chlorine, or intense humidity, durability reduces to 1–2 years. Vegetable-tanned straps develop patina over time, improving aesthetically. To extend lifespan, avoid prolonged immersion and allow complete drying between wearings.
