About This Release

The 2026 Jaeger-LeCoultre Master Hybris Artistica Calibre 945 Q5263482 pairs a blue grisaille enamel sky scene with a minute repeater and orbital flying Cosmotourbillon. Its 45mm white-gold case houses an astronomical display tracking Northern Hemisphere constellations. Only five pieces will be made.

Collector Note

The enamel painting gives this edition its identity. Its Cosmotourbillon travels around the dial once every sidereal day—approximately 23 hours, 56 minutes and 4 seconds—linking the moving display to the stars above the Vallée de Joux.

Collector Value

Collector appeal centres on the combination of hand-applied enamel, astronomical mechanics and acoustic watchmaking. Pricing is available upon request.
