When Jaeger-LeCoultre unveils a new watch in its Master Grande Tradition collection, expectations are already sky-high. The latest chapter—the Master Grande Tradition Calibre 948 with a green enamel dial—does more than live up to them. It blends fine watchmaking with miniature artistry, offering collectors a rare creation that is as much a work of art as it is a mechanical instrument.

At first glance, the watch pulls you into its dial. A domed representation of the Earth, viewed from above the North Pole, sits at the center. Each continent has been delicately shaped in pink gold and then finished with layers of vivid green enamel. The oceans shimmer with depth thanks to guilloché engraving beneath translucent lacquer, creating an effect of gentle waves moving across the seas.
This isn’t a dial you merely check for the time—it’s one you get lost in, discovering new details every time you turn your wrist.
The Tourbillon in Orbit
Powering this miniature globe is the Calibre 948, one of Jaeger-LeCoultre’s most technically ambitious movements. The standout is its orbital flying tourbillon, which doesn’t just rotate on its own axis but also makes a full circuit around the dial every 24 hours. The result is a double dance of mechanics: one revolution every minute for the tourbillon, and one every day for the world-time display.
This orbital motion isn’t simply for spectacle. It represents the rotation of the Earth itself—an elegant reminder that time is both universal and personal.
Global Time, Made Simple
As a true world-time watch, the Master Grande Tradition Calibre 948 allows the wearer to see all 24 time zones at once. A rotating city ring, aligned with a 24-hour scale, keeps track of the world’s major hubs.
Travelers will appreciate how effortless it is to adjust: moving between time zones requires only the hour hand to be shifted via the crown, leaving the precise minutes and seconds untouched. It’s practical, precise, and entirely in the spirit of Jaeger-LeCoultre’s watchmaking philosophy.
An Architecture of Elegance
The case, crafted in 18-carat pink gold, is as considered as the dial it frames. With its softly curved bezel, beveled lugs, and varied finishes—from polished to micro-blasted—it plays with light in subtle, changing ways. At 43mm, it has a commanding presence, but thoughtful ergonomics make it surprisingly wearable. A deep green alligator strap completes the aesthetic, tying the piece together in harmony.
Limited, Precious, Unforgettable
Only 20 examples of this green enamel edition exist, making it an object of rarity even in the world of haute horlogerie. Each one embodies dozens of hours of artisanal work—engraving, enameling, lacquering, and assembly—all carried out in Jaeger-LeCoultre’s Vallée de Joux manufacture.
It’s not just a watch; it’s a snapshot of centuries of craft distilled into a single, limited-edition creation.
Final Thoughts
The Master Grande Tradition Calibre 948 with green enamel is a watch that transcends categories. It’s a travel companion, a showcase of Métiers d’Art, and a demonstration of mechanical ingenuity. More than telling time, it tells a story—of the Earth, of craftsmanship, and of Jaeger-LeCoultre’s tireless pursuit of beauty in motion.
