A Unique Gerald Charles Maestro GC39 Remaster Sold at Charity Auction
The one-of-a-kind timepiece fetched CHF 107,100 at Christie’s Auction
Geneva, May 13, 2025 – During the “Rare Watches” auction organized by Christie’s at the Four Seasons Hôtel des Bergues in Geneva, a unique Gerald Charles Maestro GC39 Remaster was sold for CHF 107,100. The final price far exceeded the initial estimate of CHF 40,000 to CHF 60,000.
All proceeds from the sale will be donated to Action Innocence, a Geneva-based foundation which protects the dignity and integrity of children, teenagers, and individuals with special needs in their use of screens and digital technologies.
A Special Edition Celebrating 25 Years of Gerald Charles
Created as a one-off piece to mark the Maison’s 25th anniversary, the Maestro GC39 Remaster is a blend of heritage design and technical innovation. Based on a 2005 design by Gérald Genta, the model has been reimagined with a contemporary touch, featuring the stunning Jumping Hours complication.
Technical Features
The watch features a 42mm polished Grade 5 titanium case, a lightweight yet challenging material to work with, contributing to the model’s elegant profile (11mm thickness). The case retains the signature asymmetrical shape of the Maestro collection, inspired by Roman Baroque architecture.
The dial is made of Australian Fire Opal, a rare stone characterized by warm tones, orange, red, and yellow and natural iridescence. The dial also showcases Meta-guilloché decoration, a proprietary technique combining micromechanical precision with dynamic light play, without using colored coatings.
In-House Movement and Rare Complication
At its core is the Swiss Manufacture 4.0 Jumping Hours caliber, developed in-house. This automatic mechanical movement offers a 50-hour power reserve and includes a jumping hours complication, which allows the hour display to “jump” instantly at the top of each hour.
This is a rare and energy-demanding complication: the hour disc is 25 times heavier than a standard hour hand and requires roughly 90,000 times more energy to function compared to a traditional three-hand movement.
Customization and Accessories
The watch comes with two straps, one in orange and one in blue, along with additional options in leather, Velcro, and rubber. The sapphire crystal caseback reveals a honeycomb rotor engraved with the 25th anniversary logo, and the winning bidder will also have their initials engraved, enhancing the watch’s uniqueness.
A Noteworthy Result
This auction result underscores both the market’s growing interest in unique Gerald Charles creations and the watch industry’s increasing involvement in charitable causes. The final hammer price of CHF 107,100, nearly double the high estimate, confirms the perceived value of un a watch that stands out for its refinement in every detail.
