Marrying a tourbillon to a moon phase, new Jaeger-LeCoultre Master Ultra Thin, with rose gold case (41.5 x 12.10 mm), self-winding Calibre 983.
Jaeger-LeCoultre presents a new Master Ultra Thin uniting a moon phase display with a tourbillon
Jaeger-LeCoultre’s Master Ultra Thin collection epitomises the Manufacture’s philosophy of uniting technical virtuosity with enduring beauty, and in 2020 it is enriched by the new Master Ultra Thin Tourbillon Moon. The new timepiece combines two of horology’s most cherished complications for the first time in the Maison’s long history – a moon phase and a tourbillon, with the addition of Jaeger-LeCoultre’s signature peripheral ‘jumping’ date.
Making its debut in the Master Ultra Thin Tourbillon Moon is the new self-winding Calibre 983. For the Master Ultra Thin Tourbillon Moon, Jaeger-LeCoultre’s engineers capitalised on the 978 movement to develop the new Calibre 983, with the addition of the moon phase and ‘jumping’ date complications. 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. Beating at a frequency of 28,800 vph (4 Hz), the new Calibre 983 offers a power reserve of 45 hours.
Timeless style and a new pink gold alloy
The Master Ultra Thin Tourbillon Moon is presented in a case made of Le Grand Rose gold. Introduced this year, the new pink gold alloy has a remarkable sheen and depth of colour, and is highly resistant to fading over time. True to the classically elegant design codes of Master Ultra Thin, the case is fully polished, with elongated and bevelled lugs and a fine bezel.
Original and intriguing displays
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.
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.
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.
