Strap for Rectangular Complication Stainless Steel / Silver - Roman

The lug width of the Oris Rectangular 01 581 7658 4071-07 5 23 70FC is 23mm. This specific measurement is distinctive of the rectangular case and requires careful strap selection. Unlike standard 20mm or 22mm formats, 23mm ensures balanced tension between the case lugs whilst maintaining the aesthetic integrity of the rectangular silhouette.

The optimal strap depends on usage context and personal aesthetic preference. For formal occasions, we recommend alligator leather or vegetable-tanned calf in black or dark brown. For versatile daily wear, a Cordura NATO strap maintains formal rigour without requiring intensive maintenance. For casual sports contexts, technical rubber offers comfort and durability. Your choice should reflect the minimalist and geometric philosophy inherent to this timepiece.

Changing the strap on the Oris Rectangular 01 581 7658 4071-07 5 follows standard procedure: use a spring bar tool to gently push the elastic pin inward, thereby liberating the strap end from the case lug. Once the previous strap is removed, align the new strap's holes and reposition the spring bar until it clicks securely. With 23mm lugs, verify that the strap exhibits no excessive play, as this measurement is more selective than standard formats.

Yes, the Oris Rectangular 01 581 7658 4071-07 5 accepts any strap manufactured for the 23mm lug width, regardless of brand origin. Artisanal straps from Milano Straps are fully compatible with this case, as they conform to the standard lug width specification. However, always verify that the strap's total length accommodates your wrist size and that the keeper glides smoothly across the case lug slot.

A natural leather strap with vegetable tanning, when subjected to regular maintenance—periodic cleaning and occasional conditioning—retains functionality and aesthetic appeal for 3–5 years of daily wear. Actual durability depends on usage intensity, ambient humidity, and personal care standards. Artisanal straps from Milano Straps, crafted from premium leather, typically develop a distinctive patina that enriches the visual character over time, transforming ageing into an aesthetic virtue.
