With the SIHH 2019 only a month away, brands are pre-releasing selected models to whet our appetite. Among them is Jaeger-LeCoultre, which has unveiled a superb new version of one of its classics. Meet the Jaeger-LeCoultre Master Ultra-Thin Moon Enamel, a showcase for the artistic crafts of the Grande Maison.This year Jaeger-LeCoultre celebrates the Art of Precision – which, in the brand's own words, goes way beyond just chronometry and encompasses meticulous attention to detail and an unceasing quest for perfection. For its Pre-SIHH 2019 launch, Jaeger-LeCoultre kicks off with the Master Ultra-Thin Moon Enamel, the first watch of a series that will culminate with a Grande Complication, a new Hybris Mechanica that we are looking forward to presenting soon on MONOCHROME – but that won't happen before the SIHH itself, in mid-January. Ad - Scroll to continue with article The Master Ultra-Thin Moon Enamel is a 100-piece limited edition watch that exemplifies precise craftsmanship and discreet elegance. It is classy in its own way, with a touch of originality. The highlight of the model is, without doubt, its superb dial radiating absolute stylistic purity. It features a hand guilloche sunray pattern with straight lines traced from the centre of the dial. A blue, translucent enamel layer is then applied on its surface to bestow an intense depth and lustre to the engraved motif. The dial is manufactured in-house and is a testament to the mastery Jaeger-LeCoultre has achieved in traditional crafts (or metiers rares). It is made of several parts that are then assembled together and welded to create the final dial. Naturally, this adds complexity as the counter or mainplate of the dial are independently decorated with hand-guilloche and their motifs?have to match each other perfectly. The outer part framing the dial is made separately too. The date ring framing the moon phase indication is delicately engraved. The applied hour markers (another meticulous manufacturing step) are slightly thinner and more elongated than for the regular Jaeger-LeCoultre Master models.The white gold case is 39mm in diameter and a tad thicker than the standard Master Ultra-Thin Moon (10.04mm versus 9.9mm, mainly due to the new dial). It houses an updated movement, the Jaeger-LeCoultre calibre 925/2. Operating at 28,800 vibrations per hour, this automatic movement offers a 70-hour power reserve - a great improvement compared to the previous calibre 925/1 found in other Master Ultra-Thin Moon watches, which offered 43 hours of power reserve.This movement indicates the hours, minutes and seconds on the central axle, as well as two other indications, the date and the moon phases, both appearing in the sub-dial at 6 o'clock. Turning the watch over, the exhibition caseback allows a view of the movement finished with Geneva stripes, perlage and blued screws. A black alligator leather strap adds the finishing touch.
