The Maestro 3.0 Chronograph Clou de Paris Ice Blue seamlessly blends Gérald Charles' heritage with cutting-edge craftsmanship, featuring a sunburst ice blue dial enhanced by the Mini Tapisserie Clous de Paris pattern for remarkable depth and texture. Its polished stainless steel case, inspired by Mr. Gérald Charles Genta’s original GC33 drawing, incorporates a refined ergonomic design with ErgonTeq® technology for optimal comfort. The ice blue vulcanized rubber strap mirrors the intricate dial detailing, showcasing the Clous de Paris finish and the signature Gerald Charles logo tapisserie on the reverse. Applied baton indexes with Super-LumiNova ensure visibility, while the silver-polished chronograph counters provide precise functionality, displaying a 60-second counter at 3 o’clock, a 12-hour counter at 6 o’clock, and a 30-minute counter at 9 o’clock.

Powered by the Swiss Manufacture 3.0 caliber, the movement boasts a 50-hour power reserve, a slim 6.07mm profile, and 351 components, including finely decorated bridges with colimaçon, côtes de Genève, and perlage finishes. The golden oscillating weight, adorned with the Gerald Charles 25th Anniversary logo and honeycomb motif, adds a refined touch. Constructed for performance, the Maestro 3.0 Chronograph offers 10 ATM (100m) water resistance, a screw-down crown with an embossed logo, and a 5G shock-resistant Incabloc® anti-shock system. The see-through case back reveals the intricate mechanics, while the asymmetric polygonal case, inspired by 17th-century baroque architecture, features a signature ‘smile’ at 6 o’clock—an homage to the concave facades of Francesco Borromini’s masterpieces.
