Jaeger Le Coultre

Jaeger Le Coultre


Clear-cut lines and elegant shapes giving pride of place to functions: the Master collection returns to the fundamentals of the classic round watch. 


The unique technical nature and distinctive styling of the Duomètre clearly place it in the most exclusive echelons of watchmaking fine art. Its new-generation movement is based on an unprecedented concept nicknamed Dual-Wing. A genuine revolution in terms of watchmaking precision, the Dual-Wing concept is composed of two separate watch mechanisms connected by a shared regulating organ.


For delicate and refined women, Jaeger-LeCoultre created the Rendez-Vous line. Gracefully rounded, designed in pure Art Deco style, and graced with a precious mother-of-pearl marquetry dial, it accompanies elegant ladies around the clock. Diamond gem- setting lends the ultimate touch of sophistication to this unusual timepiece.  


The excellence, technical performance and reliability of the Master Extreme range combines tradition and innovation in a design inspired by the 1965 Memovox Polaris.


In homage to the rich past of inventor Edmond Jaeger and to the mark he left on the automobile industry, the Jaeger-LeCoultre Manufacture has created models inspired by advanced automobile technology and the world of Aston Martin.


Time as measured by an Atmos clock entails dimensions beyond human understanding: the moon phase model loses only one day every 3821 years.


Since 1833, each and every watch by Jaeger-LeCoultre has been crafted with the same passion as part of an ongoing quest for technical perfection. Each masterpiece, the legacy of more than 180 years of expertise, benefits from the very latest cutting edge technology.  



It was an invention that led to the first Jaeger-LeCoultre workshop. Since 1833, the Manufacture has not only fostered this heritage of invention, creativity and technical skill together under one roof but also constantly set out in search of innovation. 


Over 180 kinds of watchmaking expertise, from the rarest craft professions to the most cutting-edge technologies, all under one roof.


The Calibre-Maker is a watchmaker specialising in assembling and adjusting movements, also known as Calibres. Once the drawings have been finalised and the manufacturing plans precisely defined, it is possible to proceed to building a run of prototypes, generally ten or so. They are subjected to testing which can last from four to twelve months. Only after these trials are completed can the movement go into production. The care required at each step of this phase demands a considerable investment in time. For more complicated models, final approval of prototypes can take up to two years.


After machining, the calibre components are all hand- decorated like works of art. In order to live up to the technical perfection and match it with aesthetic perfection, the many beds and countersinks milled inside the bridges and plates are decorated in the smallest recesses, even those which are to be covered by other components. 


In this workshop, imperfections invisible to the naked eye are hunted down to give the case the perfect shine it deserves. To cater to this need, the workshop is bathed in a dim light contrasting with the white light focussed on each work station. Everything hinges on the work of the polisher, to attain the degree of perfection imposed by Jaeger-LeCoultre for goods named "mirror polished ". The Atmos clock has the same degree of finishing and also undergoes several post-treatments such as smoothing, diamond polishing, buffing and varnishing. 


The movement is the organ which brings the watch to life. In the workshop where it is assembled, virtuoso gestures and skills going back in unbroken continuum over 170 years, manage to awaken the inert material, and each watchmaker gives it a piece of his soul. For the beats of the mechanism will always carry the memory of the master craftsman who breathed life into it.


Jaeger-LeCoultre is one of the rare watch Manufactures to cultivate the various decorative arts which transform a timepiece into a work of art – enamelling, engraving and gem setting – all under its own roof. Enamel miniature painting is one of the rarest and most precious of all pictorial arts. Making an enamel miniature demands weeks of intense concentration, extraordinary patience and nimble fingers. Engraving also requires concentrated attention at all moments. Using the point of their graver, the engravers draw all the motifs dreamed up by the imagination of the watch’s owner. In lines or in relief, lacquered or gem-set, the engravings are like a fragment of eternity. Jaeger-LeCoultre also blends unique gem-setting techniques which brighten the finest watch creations. 


Before being admitted to the outside world, Jaeger-LeCoultre watches have to pass the 1000 Hours Control with flying colours. This series of extremely rigorous tests is much stricter than the standards imposed by the Bureaux du Contrôle Officiel Suisse des Chronomètres, the COSC, which check the movements without their cases and without complications. Whereas the Manufacture tests and certifies finished watches, reproducing the conditions of real life wear. For 1000 hours - nearly 6 weeks - all the watches have to undergo a series of tough trials. The 1000 Hours Control has established a new standard of watch quality. The buyer of a Jaeger-LeCoultre watch can thus rest assured that he owns a very high quality product of a centuries-old tradition and a long and meticulous process, in which no detail has been overlooked, and tested to the most exacting standards.


In consultation with the designer, the Manufacturer will design a movement to fit the case. The development office designs a large scale blueprint folder for each little piece using dedicated 3D software. Materials and manufacturing methods are planned here, with full knowledge of the limitations of each workstation involved in the manufacture. It’s not unusual for a folder to contain a hundred or so plans, equivalent to two years of work. This task requires perfect knowledge of all the technical angles of watchmaking.
