Jaeger LeCoultre has a history of manufacturing ultra-thin movements, including the world’s thinnest pocket watch movement, which was produced in 1903 and is only 1.38 mm thick. The contemporary model is the Cal.849 movement of the Master control series, although slightly thicker than the former, but still only 1.85 mm thick. The Master Ultra Thin series has recently launched a slightly larger version-the case has grown from an initially incredible 34 mm to 38 mm (imagine the thickness of the 34 mm version, the buckle / strap is the thickest of the watch In part, in daily clothing, they are covered by shirt cuffs, like nothing on the wrist).
The version in the picture was produced in 2008, with a limited release of 375 pieces to commemorate the 175th anniversary of Jaeger-LeCoultre, so the dial is engraved with the year. Its dial is dark chocolate, and the case is different from ordinary silver and black, and is made of rose gold. In addition, Jaeger-LeCoultre ultra-thin watches are also available in blue and soot dials. Of course, chocolate is also increasingly popular.
There are also versions with a diameter of 40 mm and a moon phase version launched in 2011. They use different movements.
