The Maestro GC2.0-RG-01, seen from the bench

The Gerald Charles Maestro GC2.0-RG-01 is a contemporary evolution of Gérald Genta's watchmaking vision, featuring an octagonal rose gold case measuring 40 millimeters in diameter. Powered by the proprietary GCA 3002 caliber with hours, minutes, seconds, and date display, this model combines precision with functional complexity. The 20-millimeter lug width represents an optimal proportion between case diameter and overall wrist presence, complementing the geometric rigor of the octagonal case with the fluidity of the integrated bracelet.

Frequently asked questions

What is the lug width of the Gerald Charles Maestro GC2.0-RG-01?

The lug width of the Gerald Charles Maestro GC2.0-RG-01 is 20 millimetres. This width has been selected to maintain optimal proportions between the 40mm case diameter and the overall wrist presence. It is essential to verify this measurement when selecting an aftermarket strap to ensure a precise and secure fit.

Which strap is best suited for the Gerald Charles Maestro GC2.0-RG-01?

The Gerald Charles Maestro GC2.0-RG-01 pairs exceptionally well with alligator straps in brown or cognac, which emphasise the luxurious character of the rose gold case. Alternatively, vegetable-tanned calf leather offers a contemporary choice with authentic patina, whilst FKM rubber straps guarantee refined sportiness. The choice depends on the intended context of use: noble leathers for formal occasions, versatile options for rubber and NATO straps.

How do I change the strap on my Gerald Charles Maestro GC2.0-RG-01?

To change the strap on the GC2.0-RG-01, you must remove the lugs (the pins connecting the strap to the case) using a specialist tool called a spring bar tool. Position the tool inside the lug spring to compress it, then gently extract the lug. Repeat for both sides. Installation of the new strap follows the reverse procedure. If you are inexperienced, consult an expert or contact the Casati Milano service for professional intervention.

Which aftermarket straps are compatible with the GC2.0-RG-01 in 20mm?

Any strap manufactured for a 20-millimetre lug width is compatible with the Gerald Charles Maestro GC2.0-RG-01. Compatibility depends solely on the lug width, not on the watch brand. Milano Straps offers an extensive selection of 20mm straps: leather (alligator, calf, shell cordovan), canvas NATO, and technical rubber straps. Always verify that the strap is specifically catalogued as 20mm.

What is the lifespan of a leather strap for the Gerald Charles Maestro GC2.0-RG-01?

A high-quality leather strap (alligator, calf, or shell cordovan) typically lasts 3-5 years with daily wear, provided regular maintenance is undertaken. Prolonged exposure to moisture, excessive heat, or chemical substances significantly reduces longevity. Technical rubber straps, conversely, offer superior durability (5-7 years), with reduced sensitivity to climatic conditions. The patina that develops on natural leathers over time does not compromise functionality; rather, it narrates the wearing history of your GC2.0-RG-01.
