Watches and Wonders 2026: Zenith New Releases

With the CHRONOMASTER Sport Skeleton, ZENITH pushes this mechanical expression further by bringing the movement to the forefront.

The sapphire dial subtly tinted from black at the periphery to transparent at its center, reveals the openworked architecture of the calibre beneath. The skeletonization has been executed with careful attention to structural integrity and chronometric performance, ensuring that the movement’s high-frequency precision remains uncompromised.

The signature tri-colour overlapping counters, grey, anthracite and blue, remain an unmistakable reference to the original El Primero of 1969. Baton-style applied markers and faceted hands coated with C1 Super-LumiNova guarantee optimal legibility, preserving the functional clarity that defines the CHRONOMASTER collection.

Visible through both the sapphire dial and caseback, the El Primero 3600SK reveals its column wheel, finished in blue, and its horizontal clutch architecture. The movement incorporates a silicon escape wheel to enhance precision and durability, as well as a stop-second mechanism for accurate time-setting. Despite its high-frequency operation, it delivers a power reserve of 60 hours. The openworked rotor, engraved with the ZENITH star, maximizes transparency while maintaining winding efficiency and mechanical balance.

The CHRONOMASTER Sport Skeleton is presented in a 41mm case distinguished by alternating brushed and polished surfaces, reinforcing its sporty yet refined character. The classic pump-style pushers preserve its chronograph lineage, while the scratch-resistant ceramic bezel, graduated over 10 seconds, ensures precise readability of the 1/10th of a second indication. Water resistance is guaranteed to 10 ATM.

In this new edition, the G.F.J. embraces a warmer, more luminous presence. The 39.5mm case is crafted in yellow gold. Its slender proportions, stepped bezel and curved lugs preserve the refined elegance inspired by 1950s chronometers, while the glow of gold enhances its contemporary presence.

Beneath the sapphire box crystal, the dial reveals a rich interplay of textures and materials. Its architecture remains faithful to the original three-part construction:

• A central disc in bloodstone, whose natural veining and inclusions ensure that no two dials are ever identical.
• An oversized small seconds counter at 6 o’clock in mother-of-pearl.
• A peripheral guilloché sector inspired by the brick façade of the ZENITH Manufacture in Le Locle as a subtle tribute to Georges Favre-Jacot’s vertically integrated vision.

Yellow gold applied markers and finely faceted hands complete the composition, balancing mineral depth with architectural precision.

Visible through the sapphire caseback, the hand-wound Calibre 135 reveals a decoration that differs from the previous anniversary edition. Here, the aesthetic returns to more classical codes: broad Côte de Genève refined hand-chamfering and a contemporary dark ruthenium finish accented by yellow gold-coloured engravings.

The architecture remains defined by its oversized balance and harmonious symmetry: A movement conceived not only as a mechanism, but as a chronometric structure. The G.F.J. stands as a focused expression of ZENITH’s chronometric culture: A watch conceived around the movement that shaped its legacy.

Released in a limited edition of 161 pieces, the G.F.J is available for pre-order exclusively from the brand’s physical and online boutiques, as well as through authorized retailers worldwide.
