For Watches & Wonders 2026, Zenith builds its presentation around two of the names that matter most to its identity. One is the El Primero, still the foundation of the brand’s high-frequency chronograph story and now pushed into fresh Chronomaster Sport executions that expand its visual and material range. The other is the Calibre 135, the observatory-bred movement now firmly established within the G.F.J. collection as Zenith’s modern expression of pure chronometry. 

This year’s releases move between those two poles with clarity. The Chronomaster Sport grows more expressive through a new two-tone edition and a skeletonized series that puts the mechanics front and centre, while the G.F.J. returns in yellow gold with bloodstone and in tantalum, each offering a distinct new setting for one of the most celebrated chronometer calibres in the brand’s history.

Zenith Chronomaster Sport Two-Tone in steel and rose gold with mother-of-pearl dial

Zenith Chronomaster Sport Two-Tone

The new two-tone Chronomaster Sport gives Zenith’s flagship chronograph a more polished and versatile expression without losing the athletic energy that defines the model. Its 41mm case combines stainless steel with rose gold across the bezel, crown and pushers, creating a stronger sense of contrast while shifting the watch into more adaptable territory. That change in tone continues on the dial, where mother-of-pearl introduces a more fluid play of light beneath the familiar overlapping 3-6-9 counters that tie the watch back to the original El Primero. Power comes from the El Primero 3600, Zenith’s 5 Hz automatic chronograph calibre, whose central chronograph hand circles the dial once every 10 seconds to display 1/10th of a second directly. Limited to 50 pieces, this latest Chronomaster Sport brings added warmth and sophistication to one of Zenith’s most established contemporary watches.

Zenith Chronomaster Sport in rose gold with black ceramic bezel, shown on rubber strap

Zenith Chronomaster Sport Skeleton

With the Chronomaster Sport Skeleton, Zenith shifts the focus from surface treatment to visible mechanics. The smoked sapphire dial opens up the watch to reveal the architecture of the El Primero 3600SK underneath, turning one of the brand’s best-known movements into the visual centrepiece of the design. At the same time, the watch holds on to the elements that define the collection, from the 41mm case and ceramic bezel to the overlapping counters, which in different executions continue to echo the original El Primero of 1969. Offered in steel with black or green ceramic bezels, in rose gold on rubber, and in a 10-piece rose gold limited edition with bracelet and baguette-cut diamond bezel, the new skeletonized range gives the Chronomaster Sport a bolder and more technical identity. Zenith also introduces a new patented folding clasp on the steel models, adding tool-free micro-adjustment and a more ergonomic construction that extends the idea of performance beyond the movement itself and into everyday wear.

Zenith G.F.J. Yellow Gold Bloodstone, where the Calibre 135 returns in a more expressive form, pairing chronometric precision with a richly textured stone dial

Zenith G.F.J. Yellow Gold Bloodstone

The latest G.F.J. makes it clear that Zenith does not see the collection as a one-off tribute, but as the natural contemporary home for the revived Calibre 135. This new edition, limited to 161 pieces, places that movement in a 39.5mm yellow gold case and pairs it with one of the most distinctive dials in this year’s lineup. At the centre is bloodstone, whose natural inclusions give each watch its own character, while an oversized mother-of-pearl small seconds display at 6 o’clock and a guilloché outer ring inspired by the brick façade of the Zenith manufacture add depth and structure. Inside, the hand-wound Calibre 135 continues the chronometric mission that made its predecessor one of the most awarded observatory movements of its era, now updated with a 72-hour power reserve, stop-second mechanism and COSC certification. More than a precious-metal variation, this release strengthens the G.F.J. as a serious long-term pillar within Zenith’s catalogue.

Zenith G.F.J. Tantalum, a darker, more concentrated execution, where the challenge of machining tantalum mirrors the discipline of precision watchmaking

Zenith G.F.J. Tantalum

If the yellow gold model brings warmth to the G.F.J., the tantalum edition takes the collection in a darker, denser and more exacting direction. Limited to just 20 pieces, it houses the Calibre 135 in one of the most difficult materials in contemporary watchmaking, a metal prized not only for its blue-grey tone and corrosion resistance, but also for the machining challenges it presents. Zenith makes that difficulty part of the watch’s appeal, framing tantalum as a material that mirrors the precision-driven discipline behind the movement itself. The dial continues the mood with a black onyx centre, grey mother-of-pearl small seconds counter and brick-pattern guilloché outer ring, sharpened further by trapeze-cut diamond indexes. Through the sapphire caseback, the Calibre 135 reveals its dark ruthenium-toned finishing, giving the entire watch a more concentrated and architectural character. It is the most exclusive G.F.J. of the year, but also perhaps the clearest example of how Zenith is using the collection to explore chronometry through different materials, textures and levels of rarity.
