Comprising more than 500 components, the caliber 945 unites three principal complications to drive its multiple displays and functions — namely sidereal time, orbital tourbillon and minute repeater.
Sidereal time referenced on the stars drives the star map at dial center, which displays in real time the night sky over the Northern Hemisphere as seen from the 46th parallel, where Jaeger-LeCoultre is located at Vallée de Joux. Moving in sync is the Cosmotourbillon, which completes one anticlockwise circuit around the dial each each sidereal day (precisely 23 hours, 56 minutes and 4.1 seconds). A golden sun-shaped pointer set at the edge of the dial indicates the month of the zodiacal calendar and solar time on a 24-hour scale for setting the watch, while Dauphine hands indicate civil time (referenced on the sun).
Literally elevating these astronomical displays is a multilevel dial handcrafted by artisans at the manufacture’s Métiers Rares (Rare Handcrafts) atelier. The domed star map is Jaeger-LeCoultre’s first use of grisaille enamel to achieve a chiaroscuro effect of dramatic contrast and shading for the night sky. In the pink gold Galaxia, the grisaille enameling extends to the outer segment of the dome with the depiction of planets; the outer dial segment of the white gold Atomium features instead a silvered filigree that alludes to the lines linking the constellations; they also look like molecule diagrams.
