The Master Ultra Thin charms any watch-enthusiast or devotee with its round shape and pure lines. Featuring an extremely thin case, this models highlights the arts of guillochage and enameling, two of the Rare Handcrafts (“Métiers Rares”) which have been kept alive for generations at the Manufacture in the Vallée de Joux. Jaeger-LeCoultre remains one of the few Manufactures offering gem-setting, engraving, guillochage and enameling at its workshops, artistic techniques that require delicate and subtle work, typically done by hand and with the assistance of machines, more often than not, over a hundred years old.

This year, technical and artistic precision takes on a new dimension. The Art of Precision stands out as the signature of Jaeger-LeCoultre.

The guilloché enamel exteriors of this new Master Ultra Thin Enamel model is a testament to precision and sophistication, where blue is featured in all its majesty – a deep, intense midnight blue which achieves perfect harmony with the case of this limited edition.

Issued in a limited series of 100 pieces, the new Jaeger LeCoultre Master Ultra Thin Moon Enamel proudly expresses its character in a pure and refined watchmaking style, which translates directly into a new hand-guilloché blue enamel dial, new hour-markers, a new polished moon, and a new engraved counter. Its extremely thin case in white gold (10.04 mm) conceals its engine, the Jaeger-LeCoultre Caliber 925, an automatic mechanical movement with a 70-hour power reserve.

A hand-guilloché blue enamel dial

The elegance of the new Master Ultra Thin Moon Enamel comes down to the assertive character of its guilloché blue enamel dial. This deep captivating blue brings to light the geometric motifs and the relief effect characteristic of guillochage, a traditional decorative technique more fashionable than ever. Enameling, this age-old expertise, was reinstated at the Manufacture in 1996. Executed completely by hand by a few artisans trained at the Manufacture, enameling requires extreme concentration and infinite patience. Furthermore, performing the guillochage work and the application of the translucent blue enamel layer requires an incomparable level of meticulous attention.

A new polished moon phase

The Master Ultra Thin Moon Enamel features a new moon phase setting, one that has been redesigned with painstaking attention to detail. When the moon is full, its perfectly round and polished white disk comes to rest on an exquisite stellar background.

A new take on hour-markers and an engraved counter

In addition to the unmistakable presence of the polished moon phase, this limited edition of 100 pieces skillfully revisits the standards of the Master Ultra Thin, a line that has been a watchmaking classic for over 20 years. Connoisseurs are sure to notice the new design of the hour-markers, which are longer and split into two at 12, 3, 6 and 9 o’clock. In an aperture at 6 o’clock, the counter that houses the polished moon phase has been engraved, a way of bringing out the numerals depicting the date. Visually, the effect is one that combines presence and discretion.
