We continue with the novelties at Watches and Wonders 2026 in Geneva, with the new Master Hybris Inventiva Gyrotourbillon À Stratosphère from Jaeger-LeCoultre. The triple-axis tourbillon construction of Calibre 178, for which several patents have been applied, ensures 98% coverage of all possible positions, making it the most precise tourbillon wristwatch with the widest positional coverage ever created by Jaeger-LeCoultre.
It also marks the inauguration of a new series within the Hybris line: Hybris Inventiva. Housed in a 42 mm platinum case with refined finishes, the calibre housing the new triple-axis tourbillon features meticulous finishing and is decorated by hand using Métiers Rares techniques such as guilloché, enamel, and lacquer, to highlight its distinctive architecture.
Jaeger-LeCoultre Master Hybris Inventiva Gyrotourbillon À Stratosphère
Jaeger-LeCoultre introduced the Hybris Mechanica series in 2003 as a collection inspired by the spirit of innovation and the desire to push the boundaries of watchmaking by combining several reinvented high-end complications into a single timepiece. The Hybris Artistica concept was presented in 2014 as a collection of existing grand complication models, designed to showcase artistic crafts such as engraving, enameling, and guilloché. Jaeger-LeCoultre now introduces a third Hybris line: Hybris Inventiva.
Watches in the Hybris Inventiva series will only feature a single complication. Until now, experimental prototypes were kept secret as purely conceptual pieces; now, after many months or even years of testing, some of them will be revealed in very limited and numbered editions. The one chosen to inaugurate this collection is the new Hybris Inventiva Gyrotourbillon À Stratosphère.
On the front of the watch, the 18-karat (750/1000) white gold movement plates are decorated with iridescent guilloché and covered with translucent blue enamel. The visible openworked bridges in 18-karat (750/1000) white gold are filled with blue lacquer to match the design, and even the covers of the two large barrels, unmistakable from the dial at approximately 2 o’clock and 10 o’clock, are hand-engraved and lacquered in the same blue.
The decoration continues on two off-centered dial rings: the upper ring, which displays the hours and minutes, reveals not only the hands’ bridge in its openworked center, but also a larger surface of the two decorated barrels. The second off-centered ring surrounds the triple-axis Gyrotourbillon À Stratosphère at 6 o’clock and features markings for 30 seconds (twice 15 seconds); the seconds are indicated by a small red arrow moving around this sub-dial. The visual elements add to the sculptural design of the calibre, which plays with volumes in a fascinating way. However, all attention remains focused on the centerpiece: the triple-axis Gyrotourbillon À Stratosphère.
The entire back of the watch is visible under a transparent sapphire crystal caseback, allowing the owner to enjoy an excellent view of the support system of Calibre 178. This features bridges in solid 18-karat (750/1000) white gold, traditionally decorated with the Côtes de Genève motif, hand-beveled, and highly polished. These are complemented by 53 jewels, some in gold chatons, whose deep red color contrasts with the monochromatic aesthetic of white gold and steel.
The manual-winding Calibre 178, which guarantees great precision, beats at 4 Hz (28,800 vph) and offers an extraordinary power reserve of 72 hours, meaning it only needs to be wound once every three days.
