HyperChrome R32260702— lug 20mm

The lug width of the Rado HyperChrome R32260702 is 20mm. This measurement represents the distance between the two spring bars protruding from the case and is critical when purchasing a replacement strap or bracelet. With a case diameter of 36mm, the 20mm lug width provides balanced proportions. To verify, use a digital calliper positioned between the two attachment pins inside the case.

The ideal strap depends on usage and aesthetic preference. For formal wear, calf leather with vegetable tanning or shell cordovan with developing patina are recommended: leather introduces organic warmth that balances the cold geometry of the ceramic case. For versatile daily use, nylon NATO straps with tight weave or high-quality FKM rubber offer durability and practicality. For those seeking a bespoke handcrafted strap, the 20mm lug width allows custom fabrication that guarantees perfect fit across the R32260702's specific case shoulders.

Strap replacement on the R32260702 is straightforward. You require a spring bar tool or small removal implement to extract the spring bars connecting the strap to the case. Insert the tool into the small opening at the base of the spring to disengage it, then remove the old strap. Align the new strap's end holes with the spring bars and press until the mechanism clicks into place. Exercise care around the ceramic case shoulders: these elements reduce available space, making precision-dimensioned straps essential.

Yes, all standard straps with 20mm lug width are compatible with the R32260702. However, the hybrid ceramic-steel case features distinct case shoulders where the lug attaches: for optimal fit without excessive play or tension, straps specifically manufactured for this width and with end dimensions to tight tolerances are recommended. Bespoke handcrafted straps guarantee superior fit across your specific case's unique shoulder configuration.

Leather strap longevity depends on tanning method and usage patterns. A calf leather strap with vegetable tanning, under moderate daily use, typically lasts 3–5 years before significant wear appears. Shell cordovan, owing to its denser fibre structure, can endure 5–7 years. Prolonged exposure to moisture, perspiration and sunlight accelerates deterioration. Leather nonetheless continues to develop characteristic patina throughout its service life. To extend longevity, apply periodic treatments with specialised balms and allow the strap rest during summer months by rotating with NATO or rubber alternatives.
