Zenith’s G.F.J. Calibre 135 Double Signed with Naoya Hida & Co. was unveiled on 2 June 2026 in a ten-piece platinum edition. The manufacturer’s launch release quotes CHF 58,900. That is a Swiss-franc launch reference, not an official UAE retail price. The interest is the specific dial treatment and modern hand-wound movement; ask Zenith for the actual reference, availability and written local quote before comparing a resale offer.
What is Zenith’s Double Signed Program?
The Double Signed Program connects a major manufacture with another watchmaking voice rather than simply changing a dial colour. Naoya Hida’s restrained approach gives this version its identity. Keep the Calibre 135’s broader history separate from the 135-O competition movements: Zenith’s release describes restored 1950s competition movements in a 2022 project, then a re-engineered modern calibre in the 2025 G.F.J. This 2026 collaboration builds on the modern revival, not an assumption that every Calibre 135 was made only for observatory trials.
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
The platinum watch uses a solid-silver dial, but not every inscription is independently hand-carved. Zenith’s release distinguishes precision engraving of the double signatures from hand engraving of the three Arabic numerals, which are filled with blue Japanese urushi lacquer. That distinction is useful: the appeal lies in how the dial is made, not an inflated claim that every mark uses the same process. The gold hour and minute hands and blue small-seconds hand complete the visual treatment.
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. The case back is sapphire, so that movement is fully on display for anyone who wants to see the finishing up close.
Why UAE collectors will want this on their radar
The UAE has firmly established itself as one of the world’s most important luxury watch markets, home to a knowledgeable collector community and the global stage that is Dubai Watch Week. For the region’s connoisseurs, a platinum, dual-signed, 10-piece limited edition exemplifying G.F.J. Calibre 135 refinements is precisely the sort of release that gets collectors talking. Zenith has confirmed more Double Signed collaborations are coming, so this debut piece is worth watching for what it signals about the direction of the programme.
With production capped at 10 pieces worldwide, anyone in the region hoping to secure one will want to move quickly and enquire through Zenith’s official channels. For collectors who value rarity, provenance and a story as much as the watch itself, this is exactly the kind of release worth tracking down. Interested buyers should quote the reference 40.1865-2.0135/01.C220 when enquiring through Zenith’s official channels.
Frequently asked questions
How much does the Zenith G.F.J. Calibre 135 Double Signed cost?
Zenith’s launch release quotes CHF 58,900. This guide does not establish a current AED retail quote; confirm price, allocation, delivery and seller terms directly for reference 40.1865-2.0135/01.C220. A currency conversion is not proof of UAE stock or an authorised local price.
How many will be made?
The release is limited to just 10 examples worldwide, making this G.F.J. Calibre 135 highly exclusive. That is a smaller run than most limited-edition dress watches from major Swiss houses, which is exactly why interested collectors are advised to enquire directly through Zenith rather than wait.
What makes this watch special?
It launches Zenith’s Double Signed Program, pairing the Swiss Maison with Japanese brand Naoya Hida & Co. on a platinum watch with a hand-engraved silver dial filled with blue Urushi lacquer and dual signatures. It is also the movement’s first appearance dressed by an outside independent watchmaker rather than restored from vintage stock, and Zenith has said this is only the first of several planned Double Signed collaborations.
When was it released?
The G.F.J. Calibre 135 Double Signed was unveiled on 2 June 2026, further cementing the G.F.J. Calibre 135 in the pantheon of iconic Zenith releases. This launch marks a new era of limited-edition G.F.J. Calibre 135 collaborations for Zenith and Naoya Hida.
Our view: the dial is the reason to study this collaboration, rather than treating a ten-piece run as an investment case. If buying, ask for the exact specification and accompanying documents. The launch page’s narrative and technical fields differ on case diameter, so confirm that dimension with the brand rather than relying on a rounded figure in a secondary article. The published movement specification is hand-wound Calibre 135, COSC-certified, with 72 hours of power reserve.
