Jaeger-LeCoultre Master Ultra Thin Tourbillon Moon

Swiss manufacture is introducing the Jaeger-LeCoultre Master Ultra Thin Tourbillon Moon, the first timepiece of the maison to combine a moonphase display and a tourbillon. The new timepiece also features a pink-gold case and a peripheral
date display.

The Jaeger-LeCoultre Master Ultra Thin Tourbillon Moon is housed in a 41.5 mm Le Grand Rose Gold case. This red-gold alloy is characterised by its strong colour, which notably does not fade over time. The case is polished on all sides, and features long lugs as well as a slim bezel. The case is water-resistant to 5 bar or a depth of 50 m.

The “eggshell-white” dial bears arrow-shaped applied gold indexes, which have a different shape depending on their position. The dauphine hands pick up the appearance of the indices and stand out against the clear background. The upper half of the dial is dominated by the moonphase display. This reflects the phases of the moon in both the northern and southern hemispheres. In addition, the two-sided hand indicates the Age of the Moon.

Meanwhile, in the lower half of the dial is the tourbillon, which also serves as a seconds display. The tourbillon cage is made of titanium and is secured by a redesigned bridge in polished pink gold. Furthermore, the wide opening provides transparency and light. The tourbillon can also be viewed from the back through the sapphire crystal caseback.

On the periphery, the Jaeger-LeCoultre Master Ultra Thin Tourbillon Moon displays the date. As with the Master Control Calendar presented in spring 2020, the manufacture integrates the “jumping” date. The date hand jumps 90 degrees from the 15th to the 16th, so as not to obscure the tourbillon.

The Movement of the Master Ultra Thin Tourbillon Moon

The new manufacture calibre 983 powers the Jaeger-LeCoultre Master Ultra Thin Tourbillon Moon. It features automatic winding and a power reserve of 45 hours. The balance, which is located in the tourbillon, oscillates at a frequency of 4 Hz. The skeletonised rotor with the JL logo is made entirely of pink gold and allows for a clear view of the movement.

Other decorations on the caliber include Geneva stripes, blued screws, circular grains and bevelled bridges. As with all Jaeger-LeCoultre timepieces, this model has an eight-year warranty. In addition, the watch has the in-house “1,000 Hours Control” certificate, which is intended to attest to the high quality of the timepiece.

The Jaeger-LeCoultre Master Ultra Thin Tourbillon Moon is presented on a bordeaux red alligator leather strap, which can be quickly and easily replaced without tools. The price for this model is 85,000 Euros.
