Jaeger-LeCoultre: Master Ultra Thin Tourbillon Moon

The Jaeger-LeCoultre collection is enriched with the new Master Ultra Thin Tourbillon Moon, the maison’s first watch that combines two of the most popular complications: a moon phase and a tourbillon, with the addition of Jaeger- LeCoultre’s signature peripheral ‘jumping’ date.

For the Master Ultra Thin Tourbillon Moon, Jaeger-LeCoultre’s engineers capitalised on the 978 movement to develop the new Calibre 983 with 45 hours of power reserve. The triple moon phase indicator – displaying the age of the moon as well as its phases in both Hemispheres – is also a recent development, having been introduced last year.

The new Master Ultra Thin Tourbillon Moon is presented in a 41,5 mm case made of Le Grand Rose gold,a new pink gold alloy characterized by a remarkable sheen and resistance to fading over time. To complete the pink gold tone, an eggshell-white dial combined with “Dauphine” hands and gold applied indexes with an elongated arrow-shape design.

Set in the upper half of the dial, the astronomical complication displays the Northern Hemisphere moon phases in the traditional way – a deep blue sky scattered with stars provides the background for a polished golden disc. 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

Per il For the peripheral date display the Manufacture’s engineers chose Jaeger-LeCoultre’s signature ‘jumping’ complication. Every month, the date hand makes 90-degree jump, gliding rapidly from the 15th to the 16th, in order not to obscure the tourbillon

The lower half of the dial is dominated by the tourbillon. A newly designed bridge in polished pink gold secures the titanium tourbillon cage as it completes one revolution every 60 seconds. On the back, the long span of the open-worked tourbillon bridge further enhances this transparency, while its Côtes de Genève decoration complements the sunray pattern of the stripes on the main plate. The open-worked pink gold winding rotor, which features the JLC logo and a combination of polished and micro-blasted surfaces, allows a clear view of the movement, with additional fine finishes including blue screws, circular graining and chamfered bridges.

Like all Jaeger-LeCoultre timepieces, the Master Ultra Thin Tourbillon Moon carries an eight-year warranty in addition to the 1,000 Hours Control certification – one of the watch industry’s most stringent testing protocols. (Price around € 89.000)
