Jaeger LeCoultre specialises in ultra-thin watches and this watch is an example of simple, elegant design. Discreet and elegant this rich blue lacquered sun-ray dial is timelessly beautiful and has a rich variety in colours and appearance depending on where and how light is exposed to it. The watch features rhodium-plated arrow indexes and hands as well as a 39mm stainless steel case with display back.
Both sides of this watch feature flat sapphire glass not only helping the watch visually appear "ultra thin" but also to provide modern protection and durability. Jaeger LeCoulture applies a thorough and rigerous testing to all their watches; their so called "1000 hour test". These "Master Control" tests include tests for accuracy, resistance to temperature, pressure, vibrations, magnetic fields and water resistance. It is their stand-in for the chronometre standard and unlike COSC certification the entire watch is tested, not only the movement.
The movement itself is a 28,800 BPH, 4HZ, 43 hour power reserve in-house movement so-called the "calibre 938". This movement is unsurprisingly quite thin and complex with a total of 237 parts, 41 jewels and a height of 4.9mm. The movement is displayed through the sapphire case-back and displays a beautifully finished movement with thermal-blue mounting screws and a skeletonised, solid gold rotor secured by ceramic ball bearings that do not require lubrication. The famous "Côtes de Genève" motif is present throughout the movement, featuring on the rotor, bridges and balance cock.
This beautiful, timeless Jaeger LeCoultre comes with full box and papers and our 12 month warranty.
