Watches Featuring the Calibre 948

This exceptional movement is the heart of the Jaeger-LeCoultre Master Grande Tradition Calibre 948 watches. These timepieces are highly praised for their sophisticated aesthetic and the use of rare handcrafts (Métiers Rares).

• Master Grande Tradition Calibre 948 (various editions): These watches often feature a domed, guilloché dial that evokes the ocean, finished with multiple layers of translucent lacquer or enamel in colors such as blue or green. They are available in various case materials, including white gold and pink gold.
• Aesthetics: Reviewers commend the unique artistic expression of the universal time display, where a map of the world is intricately depicted in the center of the dial using champlevé enamel. The user-friendly design allows the wearer to adjust the local time in one-hour increments using the crown, without interrupting the running of minutes and seconds.
