Jaeger-LeCoultre’s new Master Ultra Thin Tourbillon Moon features a distinct combination of moon phase and a tourbillon, with the addition of the brand’s signature peripheral ‘jumping’ date.

The new self-winding Calibre 983 is also making its debut with this creation. The triple moon phase indicator, displaying the age of the moon as well as its phases in both hemispheres – is also a recent development.

The suave piece adorns a case made of Le Grand Rose gold, the pink gold alloy. The eggshell-white dial provides as an ideal backdrop to highlight moon phase display and tourbillon.

The astronomical complication, in the upper half of the dial, displays the northern hemisphere moon phases with a deep blue sky scattered with stars. Surrounding this is a ring with applied southern hemisphere moon phases on the left and the Age of the Moon on the right, each indicated by a double-ended hand.

The lower half of the dial is dominated by the tourbillon. “A newly designed bridge in polished pink gold secures the titanium tourbillon cage (which weighs around 0.3 grams with its components) as it completes one revolution every 60 seconds. The fine tourbillon bridge and wide aperture maximise transparency and light, drawing the eye right through the mechanism,” the brand elaborates in an official release.

The water resistance is five bar and power reserve is up to 45 hours.
