Strap for Prestige Gold 23

The lug width of this model is 18 millimetres. This measurement is crucial when selecting a compatible strap. To verify it, use a digital calliper or millimetre ruler, positioning it perpendicularly to the lugs and measuring between the inner edges of the strap passants. A 1-millimetre error would cause either excessive tightness at the lugs or undesirable play.

For this 23-millimetre dress watch in yellow gold, an alligator strap represents the most stylistically coherent choice. The regular grain texture and natural tonality of the material enhance the formal character of the case. Alternatively, calf leather with vegetable tanning in dark brown or cognac offers superior chromatic richness and develops an elegant patina over time. Quality rubber remains the contemporary solution for those preferring daily practicality.

Strap replacement requires a spring bar tool, a specific instrument that allows you to compress the elastic pins at the lug extremities. Position the tool in the small notch of the pin, gently push inward to create space for the new strap, and slide it outward. Repeat from the other end. Avoid improvised objects that might scratch the yellow gold case. Casati Milano provides this service with personalised consultation.

A quality leather strap (alligator or calf with vegetable tanning) typically lasts 2–3 years with daily use, provided it remains protected from excessive moisture and dirt. Exposure to perspiration accelerates leather wear and may compromise colouration. A strap used occasionally may last 5–7 years. Quality rubber resists 3–4 years. Casati Milano guarantees its artisanal straps for 18 months and offers reconditioning services.
