For the first time in the collection, the case and bezel are made from colored ceramic, a material once exclusive to the round Big Bang design, with each version limited to just 200 pieces worldwide.

The new color options showcase the bold and captivating hues of Sand Beige, Dark Green, and Sky Blue, each one vibrant, scratch-resistant, and designed with a unisex appeal. These three models serve as a testament to Hublot’s relentless creativity and pioneering spirit, seamlessly blending cutting-edge design with advanced ceramics.

Their 2025 releases underscores Hublot’s spirit and commitment to pushing the boundaries of watchmaking, marking a new chapter in the brand’s ongoing legacy of innovation.

Each of the three new ceramic models boasts an exposed dial, driven by the Hublot automatic skeleton chronograph calibre HUB4700. This movement draws inspiration from the legendary El Primero, the first Swiss high-frequency calibre ever created, and its modernized successors.

The dials of each of the three new Spirit of Big Bang Chronograph watches are perfectly matched to their coloured ceramic cases, with hour markers and chronograph counters in the same tone. The rubber straps, featuring a central inlay, are also designed to complement the colour of the ceramic case.

A dynamic choreography of watch complication, the new MECA-10 boasts an exposed skeleton dial showcasing Hublot’s outstanding engineering of movement.

 Powered by two mainspring barrels, the movement’s energy level is shown via a digital display indicating the remaining power reserve in days. This is driven by a rare “crémaillère” rack system, where a linear gear engages a circular one. The mechanism features two discs rotating in opposite directions, connected by a spiral spring, creating an intuitive yet surprising differential display.

ZENITH unveils a skeletonised edition of the DEFY SKYLINE Chronograph. Its edgy openwork dial design lets its wearer admire precision of the El-Primero from every angle.

The art of skeletonisation consists of hollowing out the plate, bridges, and other components of the movement.

Designed for the fast-paced world where every second matters, the DEFY Skyline is an integrated-bracelet luxury sports watch that excels in both style and cutting-edge technical features. Fully attuned to the future of ZENITH, its dynamic geometric design takes cues from the aesthetics of the late 1960’s DEFY models. The latest iteration of the DEFY Skyline Chronograph preserves the 60’s essence of its history, while offering a bolder, more architectural take.

The openwork dial pushes the concept of finding its star even further, moving towards the modern evolution of the iconic El-Primero.

The latest DEFY Skyline is powered by the skeletonized El Primero 3600 calibre, which measures 1/10th of a second with precision, thanks to its 5Hz frequency. The central seconds hand completes a full rotation every 10 seconds for clear legibility. With a 60-hour power reserve, the bidirectional automatic winding mechanism ensures excellent functionality. 

Available in black or blue, the DEFY Skyline Chronograph Skeleton features a matching openworked dial, main plate, and oscillating weight, all beautifully finished to emphasize its intricate design and craftsmanship.

Blazened with the iconic Porsche logo on its bezel, the new TAG Heuer Carrera Chronosprint x Porsche Rallye pays tribute to the Porsche 911’s victory in the 1965 Monte Carlo Rally and the continuing evolution of their legendary partnership.

From marking the timing of that historic win to inspiring the creation of this new timepiece, the success of car number 147 solidified an enduring connection between Porsche and TAG Heuer, driving their shared commitment to innovation and excellence forward.
