Building on the success of the Maestro Premier 2021 Editions, Gerald Charles is proud to include the Gérald Genta-designed chronograph sports watch to its permanent collection. Continuing its legacy, this steel model from Gerald Charles ushers in a new era, appealing to fresh generations of watch enthusiasts. The 39mm Maestro combines ultra-thin, lightweight design with versatile elegance that transcends various styles and dress codes, making it perfect for any wearer. Despite weighing just 110 grams, the GC3.0-A Chronograph does not compromise on performance; it is water-resistant up to 100 meters and boasts enhanced shock resistance, truly defining it as a high-performing sports watch.

Ref. GC3.0A-02

The Gerald Charles GC3.0-A Chronograph re-embraces the Calibre Ref. GCA3022/12, an automatic chronograph movement evolved from the GCA3002. This movement is notably slender, measuring just 6.07mm in height including its bi-directional rotating oscillating weight, and boasts a robust twin-barreled 50-hour power reserve. In this iteration, the GC3.0-A Chronograph features raised flanks that enhance its squarer, more octagonal shape, alongside extended, rounded lugs that improve ergonomics. It retains the unique, irregular-shaped pushers that blend seamlessly with the case flank, preserving and accentuating the Maestro’s distinctive silhouette. Crafted in steel, the GC3.0-A Chronograph exudes a casual yet sophisticated charm, in line with Monsieur Genta’s artistic legacy. The dial, finished in sunburst, plays with light, while the Clous de Paris motif on the vulcanized rubber strap adds intriguing shadows to the wrist, making it a standout piece in any collection.
