Strap for Divers Carlos Coste Chrono Limited Edition

The lug width of the Oris Divers 01 678 7598 7184-Set is 24mm. This measurement represents the distance between the two spring bars located at the case extremities in titanium. To verify strap compatibility, this distance must be measured with millimetre precision, as even minor deviations would cause unwanted play during use, especially during diving.

The ideal choice depends on intended use. For daily versatility and formal elegance, we recommend an alligator strap with vegetable tanning, which develops patina over time and naturally complements the brushed titanium case. For frequent diving, a resilient NATO textile offers practicality and tool-free quick changes. For professional divers, vulcanised rubber ensures rapid drying and immunity to salt corrosion. All materials are available in 24mm lug width from Milano Straps.

The 01 678 7598 7184-Set uses standard spring bars (elastic pins). To change the strap: 1) obtain a spring bar tool (small implement with bifurcated end); 2) position the tool vertically beneath the spring bar, gently pushing upward to compress the internal spring; 3) extract the spring bar once the spring yields; 4) insert the new spring bar, aligning it perpendicular to the lug. A task of mere seconds, causing no case damage if executed carefully. Milano Straps provides detailed instructions with every strap.

All artisanal straps manufactured with 24mm lug width are compatible. Milano Straps offers exclusively bespoke straps measured and physically tested on this specific geometry. Collections include vegetable-tanned alligator leather, shell cordovan, military NATO textiles, and vulcanised rubber, all in 24mm size. Each piece is verified to ensure perfect spring bar alignment and absence of lateral play.

An alligator or shell cordovan strap, when subjected to ordinary maintenance (monthly cleaning, biannual conditioning with natural balms, immediate drying after water contact), guarantees 5–7 years of daily wear, extending to 10+ years with occasional use. On a diving watch such as the 01 678 7598 7184-Set, we recommend alternating with rubber or NATO straps during periods of intensive diving to extend leather lifespan. The patina developed over time becomes part of the piece's appeal.
