Artistry Meets Innovation
In an era where the watchmaking industry continuously evolves, few collaborations capture the imagination like the Zenith G.F.J. Calibre 135 Double Signed with Naoya Hida & Co. This remarkable timepiece represents a confluence of Swiss horological tradition and Japanese artisan craftsmanship, heralding a new chapter for both brands. With only ten limited editions available, this watch is not just a timekeeper; it is a celebration of meticulous design and cultural exchange.
The Legacy of the G.F.J. Collection
The G.F.J. collection, named after Zenith’s illustrious founder Georges Favre-Jacot, has roots that trace back to 2022. Originating with the Zenith Caliber 135 Observatoire Limited Edition, this line showcased ten meticulously restored movements from the 1950s. Collaborations with luminaries such as Kari Voutilainen and auction house Phillips set the stage for what would become a modern revival of the Calibre 135.
Fast forward to today, the G.F.J. line has evolved to include multiple iterations, each more stunning than the last. From platinum adorned with lapis lazuli to tantalum paired with onyx, each piece has ushered in a new era of luxury watchmaking that commands attention and respect in elite circles.

Introducing the Double Signed Concept
The latest iteration, the G.F.J. Calibre 135 Double Signed, takes this legacy a step further. Crafted in a substantial 39.15mm platinum case, this timepiece retains the elegance of its predecessors while introducing a distinctive visual flair through its collaboration with Naoya Hida & Co. A hallmark of this partnership is the exquisite dial, crafted from solid silver and expertly hand-engraved by master engraver Keisuke Kano. This unparalleled attention to detail is evident in the meticulously crafted hour markers, numerals, and the intertwined signatures of both brands.
Complementing the artistry of the dial, the watch features a heat-blued seconds hand that gracefully adorns the subdial at 6 o’clock. The hour and minute hands, exquisitely machined from solid gold, echo the soft, rounded aesthetics of Hida’s celebrated Type 2 design.
A Glimpse into the Movement
Turning the watch over unveils the heart of this masterpiece—the Calibre 135 movement. With a frequency of 2.5Hz and a Breguet overcoil, this caliber is not only COSC-certified but also boasts a remarkable 72-hour power reserve. Its intricate decoration, featuring Geneva striping and anglage performed by hand, highlights the exquisite craftsmanship synonymous with both Zenith and Naoya Hida.
Straps of Distinction
The G.F.J. Calibre 135 Double Signed does not stop at its visual appeal; it also includes a trio of exceptional straps that enhance its versatility. Crafted from indigo-dyed denim sourced from the prestigious Kahihara Denim mill in Fukuyama, one strap pays homage to Japanese textile artistry. Another strap, made from Wagyu leather in Kyoto, adds a luxurious touch, while the final option features a unique lacquered, pebbled texture from Himeji Kurozan leather. This thoughtful selection of materials ensures that wearers can express their personal style while honoring the watch’s rich heritage.

A Collector’s Dream
With an asking price of $75,000 and only ten pieces available, the G.F.J. Calibre 135 Double Signed is poised to become a coveted collector’s item. The intersection of Zenith’s storied legacy and Naoya Hida’s independent spirit creates a unique narrative that resonates with aficionados and collectors alike. The watch is not merely a tool but a symbol of artistry, craftsmanship, and cultural convergence.
As the watch community eagerly anticipates the next chapter in this collaboration, the G.F.J. Calibre 135 Double Signed stands as a testament to the beauty of blending two worlds. This exquisite timepiece invites admirers to partake in a journey that transcends borders and time, making it a quintessential addition to any discerning collection.
