Jaeger-LeCoultre Manufacture Factory [Watch History]



A pencil, a blank sheet of paper, and above all the Jaeger‑LeCoultre philosophy are all designers need to draw the faces of watches destined to become legends. First comes the sketch. Their initial role is to outline the ideas, display a function, or visualize a new concept. They are interpreters of the Manufacture’s language of shapes. Always attentive to current tastes, but with one eye turned towards the future, they remain true to Maison’s long traditions. It is precisely this fusion of eras – this alchemy between past, present, and future – that characterizes the design of a Jaeger‑LeCoultre watch.

Decorating the parts

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 another unit the last complex and delicate operation on the plates and bridges – the jewelling, or setting of rubies – takes place. In use since 1902, these rubies have four functions: positioning the gear trains on the plates and the bridges; reducing friction; prolonging the piece’s lifetime; and serving as oil reservoirs for lubrication.
