Richemont Group Jaeger-LeCoultre has announced a deluxe iteration of one of its most popular models, the Master Ultra Thin Moon. First introduced in 2012 with galvanic finish dials, the new Master Ultra Thin Moon has been upgraded with a deep blue flinqué enamel dial, in a limited edition of 100 pieces.
Flinqué enamel is a combination of enameling and engine-turning. The dial base is first engraved with a guilloche pattern – done here the traditional way using a hand-operated rose engine – then painted with liquid enamel. It’s then fired in an oven to harden the enamel. The process is repeated several times until the desired color is achieved, after which the dial is then polished to give it a smoother surface and clear sheen.
With the new finishing skill, several elements of the dial have been redesigned, giving it a greater degree of detail. The enameled Master Ultra Thin Moon features slim, delicately elongated hour markers, a mirror-polished moon as well as a relief engraved date track with a frosted finish.
JLC ultra-thin automatic caliber 925/2 that stands just 4.9mm. It comprises 246 parts and has a 70-hour power reserve. The rotor is made of 18k rose gold, open-worked to form a large Jaeger-LeCoultre logo. In typical Jaeger-LeCoultre style, the movement is decorated attractively, albeit mechanically, with the bridges finished with Geneva stripes, along with blued screws and perlage on the base plate.
