Inspired by the classic “Montre à Guiché” or “window clock” style, the original 2005 model featured a sliding hour complication developed by Antoine Preziuso, legendary master watchmaker and friend of Gerard Charles. It tells the time by means of a rotating disc visible through an opening in the dial.

Like all Maestro watches, the original GC39’s esoteric case shape was inspired by forms Genta observed in Rome’s magnificent Baroque monuments designed by master 17th-century architect Francesco Borromini. This façade gives rise to the asymmetrical case, flowing bezel, and convex “smile” at 6 o’clock.

This watch has become one of the Maestro’s most popular models and today stands as a striking example of Gerard Charles’ creativity, watchmaking ingenuity and technical excellence. Giviani says: “Everything we do today is a testament to the unique talent of Maestro Gerard Charles Genta and his uncompromising spirit. “The GC39 25th Anniversary model is a joyful celebration of Genta’s creativity and love of fine watchmaking, and a testament to our continued pursuit of aesthetic and technical excellence.” The Maestro GC39 25th Anniversary model is a modern take on this groundbreaking original model for discerning watch collectors. In keeping with Mr. Genta’s strict principles of constant improvement, this new watch enhances the original concept with high-concept decoration and elegant finishes, as well as an excellent manufacture movement developed by the Maison’s watchmakers. The Maestro GC39 25th Anniversary model is characterized by its familiar stepped, flowing case shape, luminous dial, and playful time display. Opening the dial at 12 o’clock reveals a 12-hour disc and the “Jumping Hours” complication, with the disc jumping in hourly increments every 60 minutes. The time is read using this disc and the blue-painted center hour hand, but the hour hand is a skeleton and reflects light This dial inherits Mr. Genta’s extraordinary artistic creativity and the parallel ability of cutting-edge technology to realize it. This dial is painstakingly crafted from three different components and materials, with a partially hidden baroque multiraister motif that glimmers in the light. This mesmerizing effect is created by a new precision microchemical engraving technique called metaguilloché, developed exclusively by Gerard Charles.

A second engraving is then applied and the protective layer is removed, creating a star-like sparkle in the light. The engraving has rounded grooves, and the three-dimensional surface catches light in a non-linear way, using the laws of physics to create a unique aesthetic and wearability. Another advantage is that this technique extracts a very thin layer, ensuring the watch is slim and lightweight. At the center of the dial is a delicate piece of lapis lazuli shaped to follow the silhouette of the Maestro’s distinctive case. This sparkling blue semi-precious stone was chosen in homage to Mr. Genta, who loved lapis lazuli and used it in many of his designs. Like a star or Baroque statue, light emanates from the lapis lazuli center of the dial, surrounded by a blued steel Maestro-shaped part, a black minute track, and a blued steel five-minute counter. The dial features a special logo marking the Maison’s 25th anniversary.

Like the original GC39, this model is designed around a basic square, whereas the standard Maestro is rectangular. Despite the complex case design and jumping hours of the movement, the Maestro GC39 25th Anniversary model is only 11mm thick. However, as it is made from polished grade 5 titanium, it retains the lightweight, ergonomic quality that Maestro is now well known for. Materials are a crucial element for Gerald Charles watches. Titanium is a difficult material to work with, but thanks to the ambition and tireless efforts of the Maison’s craftsmen, a solution has been found that maintains both the Maestro’s iconic case shape and wearability. It also features a screw-down crown, water resistance to 100 meters, a blue Clous de Paris vulcanized rubber strap and a polished grade 5 titanium deployant buckle. They represent Maestro’s sporty heritage and the Maison’s commitment to creating versatile, high-end watches that seamlessly transition from work to play and day to night. Behind the captivating dial of the Maestro GC39 25th Anniversary model lies an equally captivating mechanical caliber. The new Gerald Charles Swiss Manufacture 4.0 Caliber Jumping Hour is developed in-house and patented by Gerald Charles. It features a jumping hour function and a 50-hour power reserve, and features 80 additional components compared to a standard time-only movement.

When developing the Swiss Caliber 4.0 Jumping Hour, the Maison’s craftsmen had to contend with difficult physics. In the course of advancing one hour, the jumping hour disc consumes the same energy as a mechanical movement normally consumes in 3,600 seconds. At the same time, the jumping hour disc is 25 times heavier than a traditional hour hand. Considering that Newton’s second law of motion states that force is equal to mass times acceleration, this complication requires 70,000 times more force than a three-hand watch. This is why the Jumping Hour is such a rare watch, and why it continues to fascinate the Maison in the spirit of its illustrious founder. In keeping with Gerard Charles’ uncompromising approach to watchmaking, the movement components are beautifully hand-finished with Côtes de Genève stripes and a circular grain finish, using techniques perfected over generations by the Maison’s artisans. The movement gears are also rhodium-plated, quietly but powerfully symbolizing Gerald Charles’ commitment to beauty and absolute quality.

This special 25th anniversary logo will be featured on all new Gerald Charles releases in 2025. Gerard Charles has significantly expanded its watchmaking facilities in Geneva and now manufactures many of the components required for the Swiss Caliber 4.0 Jumping Hours in-house. This is the next important step in the Maison’s vertical integration journey.

The technical challenge behind it is as big as landing a SpaceX rocket in microform. But that’s what makes this watch so interesting, so beautiful, and so exciting to be able to reintroduce it to Gerald Charles collectors.” Maestro GC39 25th Anniversary Model Model Details REF:GC39-TNPS-LSEN-RSDP-REM Price: 7,757,750 yen (tax included/estimated price) Limited number: 100 pieces

Mr. Genta, who was known as the “Picasso of the watch world,” served as the company’s top executive for three years, before selling the company to the Giviani family, an Italian watch industry family with whom he had close friendships, in 2003, and remaining as chief designer until his death in 2011. From 2003 to 2018: “Franco Giviani” The former CEO will lead the organization, and from 2019, his son “Federico Giviani” will take over as CEO, and in 2019, the company will welcome new shareholders.

Gerald Charles’ designs are inspired by the profound creative beauty of Baroque architecture, and are primarily inspired by the Basilica of San Carlo alle Quattro Fontane, a church that represents Baroque architecture in Rome. The exquisite combination of hexagons, octagons, and crosses found on the interior walls of the church is beautifully reflected in the case, creating an original design unlike any other watch. The rounded case design at 6 o’clock is Mr. Genta’s smile line, and it is said that Mr. Genta himself left behind a portrait of him. The perfect balance of creativity and technical expertise results in an elegant and sporty finish. All current models are based on Mr. Genta’s original design designed in 2004, and all collection names are named after his nickname, “Maestro.” Regular collection “Maestro 2.0 Ultra Thin”, “Maestro 2.0 Ultra Thin GC Sport” developed with a left crown to prevent damage to the back of the hand during sports (two models are limited to 200 pieces worldwide), and “Maestro 3.0” with a heavy chronograph specification. “Maestro 8.0 Squelette” with skeleton specifications, whose movement was developed from scratch by Octavio Garcia, former chief designer of world-famous luxury watches and current creative director of “Gerald Charles”; “Maestro 9.0″ developed based on the Maestro Flying Tourbillon designed by Genta in 2005. Tourbillon” (limited to 50 pieces worldwide), and “Maestro GEM SET” (each model limited to 10 pieces worldwide) decorated by “SALANITRO”, a Swiss jewelry design company that decorates many luxury jewelry brands. Furthermore, the movement was jointly developed with Vaucher Manufacture Fleurier, and all models are waterproof to 100 meters and durable enough to withstand 5G shocks, making them masterpieces with an emphasis on performance. It is also called the “ultimate watch” because it can be used for any occasion, from formal attire to sports. Due to its highly reliable performance, it was selected as the official timekeeper for the 2023 Generali Open (ATP250) tennis tournament held in Kitzbühel, Austria. In fact, many professional tennis players have worn them during matches, including Nikoloz Basilashvili, Hubert Hurkacz, and Tim Van Rijthoven. In addition, many athletes and celebrities such as professional soccer players, cricket players, and motorbike racers use the watch, and its outstanding design and practicality captivate them. In order to entertain such loyal customers, a dedicated salon staffed by a Michelin-starred chef and watchmaker was completed in 2023 on Avenue Mont Blanc in central Geneva. This salon was also Mr. Genta’s residence during his lifetime, and patrons can fully enjoy the worldview of Gerald Charles. In 2024 and 2025, “Gerald Charles” shows no signs of slowing down, with a booth set up at the main venue of Watches & Wonders.
