Mechanical watches with visible gears have been gaining popularity for the past few years, and now Jaeger-LeCoultre has launched thinnest mechanical watch collection Master Ultra-Thin Squelette.

The Master Ultra-Thin Squelettecollection with thickness of mere 3.6mm is a demonstration of the exceptional expertise and watchmaking skills of the artisans of the Grande Maison. The collection has four models:  18k pink gold, 18k pink gold set with brilliant cut diamonds, 18k white gold, or 18k white gold set with brilliant cut diamonds.

With a skeletonized face that can be viewed on both sides and 19 jewels, the timepieces feature a hand-wound movement and the Jaeger-LeCoultre Calibre 849ASQ, which contains 119 components and has a power reserve of 33 hours. The watches comes with Alligator leather straps and features pin buckle.

The gold surrounding the skeletonized movement is first adorned with a guilloché motif. Then enamel is applied in either a deep blue for the white gold model or a “frosted chestnut brown” for pink gold version. For one white-gold model, mother-of-pearl is applied. The gold chapter ring is divided into 12 zones that make it easy to view the numerals within its limited space. Each model is issued in a 100-piece limited series.
