Unveiling Horological Masterpieces: Zenith's GFJ Bloodstone & Tantalum Editions

Zenith's Enduring Legacy: A Celebration of Craftsmanship

Last year, Zenith marked 160 years of watchmaking prowess, a milestone celebrated by the revival of its iconic Caliber 135 movement in the G.F.J. watch. This elegant, hand-wound dress piece, initially launched in platinum, paid homage to founder Georges Favre-Jacot and Zenith's unparalleled chronometry heritage. The 2025 G.F.J. captivated enthusiasts with its lapis lazuli dial, perfectly complementing the anniversary's blue aesthetic. Now, Zenith brings its anniversary celebrations to a close with two remarkable new G.F.J. references: an 18kt yellow gold model with a distinctive bloodstone dial and a sophisticated tantalum version featuring an onyx dial and diamonds.

Design Evolution: Merging Tradition with Modernity

The new G.F.J. models maintain the original's elegant proportions, measuring 39mm in diameter, 45.75mm lug-to-lug, and 10.5mm thick, with a crown positioned at 3 o'clock. Their stepped bezel and curved lugs echo the classic designs of the 1950s, a tribute to the watches that originally housed the Caliber 135. With these new releases, the G.F.J. collection emphasizes its embrace of diverse and luxurious materials. While yellow gold remains a classic choice, the inclusion of tantalum is particularly noteworthy. This challenging material, known for its "sticky" nature during machining, requires exceptional skill and precision, a testament to Zenith's engineering capabilities.

Exquisite Dials and Flawless Detailing

The latest G.F.J. watches derive their informal names from their most striking features. The 18kt yellow gold model boasts a rare bloodstone dial, a green jasper adorned with red flecks, offering a unique aesthetic in a market increasingly saturated with stone dials. The tantalum variant, on the other hand, presents a sleek black onyx dial, enhanced by the iridescent sheen of its small-seconds subdial. Both models feature mother-of-pearl subdials that seamlessly integrate with their respective dial themes. The bloodstone dial is paired with 18kt yellow gold hands and markers, while the tantalum version features white gold hands and 11 trapeze-cut diamond markers. A recurring design element from the previous year is the brick-pattern guilloché outer ring, subtly concealing the minute markers. A sapphire box crystal protects these intricate details, ensuring a water resistance of 5 ATM.

The Legendary Caliber 135: A Movement of Distinction

The Caliber 135 movement within these new G.F.J. watches is a masterpiece, celebrated for both its aesthetics and its storied history. While last year's G.F.J. featured a unique brick motif, the 2026 editions showcase a more traditional "Geneva Stripes" decoration. Even with this refined finish, the movement remains visually stunning, characterized by its oversized balance wheel and offset center wheel. The Caliber 135 stands out for its unparalleled pedigree, having amassed over 230 chronometry prizes, making it the most awarded movement of all time. Despite its relatively low frequency of 2.5 Hz, it boasts an impressive accuracy of ±2 seconds per day. This manual-wind movement also delivers a substantial 72-hour power reserve, a testament to its efficient design.

Straps and Exclusivity: Tailored for Discerning Collectors

Both new watches come with nubuck alligator straps, each thoughtfully designed to complement its specific model. The bloodstone version features a beige strap with 18kt yellow gold hardware, while the tantalum model is fitted with a blue strap and a titanium pin buckle—an interesting detail given the challenges of working with tantalum. Zenith continues its tradition of offering generous strap options, including two extra leather straps with each purchase: green alligator and black calfskin for the bloodstone, and black alligator and grey calfskin for the tantalum. An 18kt yellow gold bracelet with a double-folding clasp is also available for the bloodstone model, likely as a made-to-order option. These new G.F.J. models are limited editions: 161 pieces for the bloodstone version, aligning with the brand's age, and a mere 20 pieces for the tantalum variant, reflecting the material's demanding production process. Prices begin at $51,900 USD for the 18kt gold bloodstone version (Reference: 30.1865.0135/56.C216) and $83,400 USD for the tantalum variant (Reference: 98.1865.0135/21.C205).
