LE LOCLE / GENEVA, April 14, 2026: At Watches and Wonders 2026, Zenith unveils the most exclusive interpretation yet of its "G.F.J.": an extremely rare "G.F.J." limited to just 20 pieces, featuring a tantalum case and baguette-cut diamond indexes. Named after Zenith founder Georges Favre-Jacot, the "G.F.J." was conceived as a modern centerpiece for Caliber 135, the most awarded chronometer movement in watchmaking history. The "G.F.J." collection goes beyond mere re-editions, serving as a platform to explore all realms of technical innovation, where chronometer precision extends into the world of rare, high-tech luxury materials that are inherently challenging to work with. This time, the rigorous mechanism of Caliber 135 is housed in a case made of tantalum. Tantalum, due to its high density and resistance, requires extremely precise control during handling. Zenith has elevated the inherent strength of this material into a defining characteristic of the timepiece's individuality. Tantalum is characterized by its high density and numerous constraints. Its natural blue-grey hue possesses a subtle luster, offering a deep metallic texture that is neither reflective nor matte. While excelling in corrosion resistance and biocompatibility, it is also known for being extremely difficult to machine. Due to its hardness and weight, processing requires special tools, wider tolerances, and meticulous finishing. Tantalum is one of the most challenging metals to work with in modern watchmaking. Its extreme hardness and high density resist machining, making finishing at each stage exceptionally difficult. Its reaction to tools is fundamentally different from gold or platinum, and achieving the same level of precision in finishing requires extended manufacturing time, mastery of special handling techniques, and complete control. The 39 mm diameter case inherits the characteristic stepped bezel and sculptural lugs of the "G.F.J.", while the tantalum material lends it a new personali
