Zenith has officially unveiled one of the year’s most quietly significant releases: the G.F.J. Calibre 135 Double Signed with Naoya Hida & Co. Launching on 2 June 2026, limited to just 10 examples and priced at $75,000 (around AED 275,000), it’s a watch built for serious collectors — and a fitting one to land in a market like the UAE. In fact, the G.F.J. Calibre 135 is already sparking conversation among enthusiasts worldwide, especially those seeking rare G.F.J. Calibre 135 editions.
It also marks the debut of Zenith’s new “Double Signed Program”, and that’s the bigger story here. The special G.F.J. Calibre 135 stands as the showcase for this exciting initiative. For fans of rare Zenith collaborations, this G.F.J. Calibre 135 is a centerpiece worth noting.
What is Zenith’s Double Signed Program?
The programme revives a golden-age tradition: watchmakers co-signing a masterpiece as a seal of shared heritage. For this inaugural release, the Swiss Maison has partnered with independent Japanese brand Naoya Hida & Co., a name revered among enthusiasts for its meticulous sense of proportion and its deep respect for mid-century mechanical watchmaking. Notably, this collaboration produces the G.F.J. Calibre 135 in a way that celebrates both brands’ heritage while highlighting the importance of the Calibre 135 G.F.J. story in watch history. For collectors, the G.F.J. Calibre 135 mechanical marvel exemplifies a fusion of craftsmanship from both Switzerland and Japan.
The collaboration grew from a genuine connection between Zenith’s Chief Product Officer, Romain Marietta and founder Naoya Hida, who has admired the legendary Calibre 135 since the 1990s. The result is a watch that reads as a conversation between Swiss horological precision and Japanese artisanal craft, rather than a logo exercise—a unique dynamic embodied by the G.F.J. Calibre 135 partnership.
The watch: dial, case and movement
Housed in a 39mm platinum case, the timepiece centres on a solid silver dial with hand-engraved indications filled with deep blue Japanese Urushi lacquer — the kind of detail that rewards a close look — and dual signatures from both Zenith and Naoya Hida & Co. This craftsmanship, especially in the G.F.J. Calibre 135 model, also features meticulous finishing, from the gold hour and minute hands to a heat-blued steel small seconds hand. On top of that, among the details, the G.F.J. Calibre 135 by Zenith and Naoya Hida displays artistry rarely seen in limited editions.
Flip it over, and a sapphire caseback reveals the hand-wound Calibre 135, offering a 72-hour power reserve and COSC certification, dressed with Geneva stripes, ruthenium treatment and yellow gold accents. Among current releases, the G.F.J. Calibre 135 stands out with technical highlights like a large variable-inertia balance wheel, a Breguet overcoil and Charles Fleck’s double arrow regulator — a serious watchmaking pedigree under a deliberately restrained exterior. It even arrives with three distinct straps: Himeji Kurozan leather, Kyoto Wagyu leather and Kaihara indigo denim. Not to be overlooked, the G.F.J. Calibre 135 movement at the heart of this model is a true centerpiece for connoisseurs.
