Zenith: The G.F.J. Calibre 135 Wins at the GPHG and Receives Chronometer Certification
The COSC extends its warmest congratulations to Zenith for winning the 2025 Chronometry Prize at the GPHG with the new G.F.J.
A legendary calibre reinterpreted for contemporary precision
Created to celebrate the Manufacture’s 160th anniversary, Calibre 135 is reborn today in a redesigned architecture that meets the highest standards of the 21st century, while remaining true to the aesthetics of the historic movement.
“Few movements in the history of watchmaking have embodied precision as profoundly as Calibre 135. In reinterpreting this legendary calibre, our teams approached every detail with the utmost respect for its original spirit. Receiving the Chronometry Prize is a meaningful recognition—both of our heritage and of our ongoing commitment to the values that have guided ZENITH for more than 160 years.” - Benoît de Clerck, CEO of ZENITH WATCHES
A certification that underscores a pursuit of excellence
COSC is proud to have accompanied this project, driven by a commitment to precision, rigor, and the transmission of exceptional technical heritage. This dedication enabled Calibre 135 to meet—and surpass—the criteria required for chronometer certification. Calibre 135 confirms that tradition and modern technology can come together to achieve remarkable levels of performance.
