Across three days at Watches and Wonders Geneva 2026, watchmakers placed a clear emphasis on chronographs, high complications and technical experimentation. From reworked chronograph architectures to increasingly complex astronomical displays and perpetual calendars, the fair highlighted a shift towards mechanical depth and functional innovation. Rather than incremental updates, many brands focused on rethinking how familiar complications are designed, displayed and used.

Chronographs Take the Lead

TAG Heuer Monaco Evergraph

Beyond Rolex, TAG Heuer introduced the Monaco Evergraph, pushing the boundaries of the chronograph. Historically central to the brand, the complication is reimagined here with the support of Vaucher. The Evergraph departs from traditional chronograph architecture, eliminating components such as levers, cams, clutches and even the column wheel, while remaining fully mechanical. Building on its earlier split-seconds innovation, this model represents a fundamental rethink of how a chronograph functions.

Parmigiani Fleurier Tonda PF Chronographe Mystérieux

Speaking of Vaucher, Parmigiani Fleurier’s movement maker is having a banner chronograph year because the Tonda PF Chronographe Mystérieux also present an all-new vision for the complication. While the good folks at TAG Heuer keep most of the clever thinking under the dial, Parmigiani Fleurier opted to reinvent how the chronograph looks.

Instead of reworking the internal mechanics alone, the brand focuses on visual minimalism. The chronograph is concealed beneath what appears to be a simple three-hand display, though the watch actually features five hands. With a combination of one vertical and two horizontal clutches, the technical complexity remains hidden beneath a restrained exterior.

Celestial Complications and Technical Depth

Patek Philippe Ref. 6105-001G

Day 2 shifts focus to astronomical complications, led by Patek Philippe’s Ref. 6105-001G. Classified as a grand complication, it introduces several firsts for the brand, including sunrise and sunset indications and the ability to account for daylight saving time. The 47mm case accommodates a rotating night sky display calibrated to Geneva, reinforcing both its scale and technical ambition.

Also from Patek Philippe, the Ref. 5840P-001—known as the Cubitus Perpetual Calendar—stands out for its shaped movement and skeletonised automatic calibre with micro-rotor. While visually striking, it maintains the brand’s signature finishing. Alongside it, a lesser-publicised reference revisits a heritage pocket watch concept with an automaton-based hours-and-minutes display, combining technical complexity with a more playful execution.

Grand Seiko SBGZ011 “Mystic Waterfall”

Grand Seiko Ref. SBGZ011

Grand Seiko’s SBGZ011, nicknamed “Mystic Waterfall,” highlights artisanal craftsmanship. Fully hand-engraved across its surface, the watch is powered by the manually wound Spring Drive calibre 9R02 from the Micro Artist Studio. Limited to 50 pieces, it continues the brand’s tradition of nature-inspired design, referencing the Tateshina Otaki waterfall while emphasising fine finishing and texture.

High Complications Return to Focus

IWC ProSet Perpetual Calendar

On Day 3, IWC introduced the ProSet perpetual calendar, a significant development in high complications. Building on its historic single-crown system, the new mechanism allows for both forward and backward adjustments — addressing a long-standing limitation. The removal of the traditional grand lever marks a key technical shift, positioning this as a major evolution in perpetual calendar design.

Van Cleef & Arpels Midnight Jour Nuit Phase de Lune

Van Cleef & Arpels presented the Midnight Jour Nuit Phase de Lune, combining a 24-hour display with a moonphase complication. The entire dial rotates over 24 hours, with the moonphase integrated into the animation. Uniquely, the moon can be obscured by the guilloché section, with an on-demand pusher at 8 o’clock revealing the full display without affecting accuracy. The piece reflects the brand’s narrative-driven approach to watchmaking while maintaining technical sophistication.
