Strap for Villeret Squelette 8 Jours Red Gold / Diamond

The lug width is precisely 20mm. This is the open space between the lugs where the strap passes through. Accuracy is critical: a 19mm strap will sit loose and unstable, whilst a 21mm strap will not fit at all. Measurement should be taken with callipers inserted perpendicular to the lug aperture, excluding the strap spring bars.

Alligator in dark tones (black, deep brown) provides optimal aesthetic harmony with red gold—creating contrast without chromatic competition. Shell cordovan represents the pinnacle: natural structural rigidity and inherent lustre amplify gold brilliance. Vegetable-tanned calf develops patina over time, creating noble ageing. NATO fabric straps maintain versatility for informal settings without contradicting the model's formal character.

Use a spring bar tool (bifurcated tip). Insert the tip between the lug and the strap's passant, gently compress the internal spring bar until the pin releases from its seat. Repeat on the opposite side. To install the new strap, align the pin with both seats and press until you feel a distinct click. Movement should be fluid—never force. For red gold cases, professional guidance from a watchmaker is advisable to prevent case scratching.

Yes, provided it is precisely 20mm width. Quality aftermarket straps—such as those from Casati Milano—meet equivalent manufacturing standards to OEM units and often provide superior aesthetic variety. Always verify 20mm lug width and confirm attachment compatibility (pin and passant configuration). A high-quality artisanal aftermarket strap permits personal stylistic expression whilst maintaining complete technical compatibility.

Lifespan varies by leather type and usage intensity. Quality alligator (Casati Milano standard) resists 4-6 years with moderate daily wear. Shell cordovan extends to 6-8 years. Vegetable-tanned calf, being softer, typically lasts 3-4 years under intensive use. Patina development indicates natural ageing, not deterioration. Sun exposure, perspiration and humidity accelerate wear. Casati Milano provides 18-month warranty against manufacturing defects, independent of natural wear.
