If there’s a model that is aware of the place the Vallée de Joux’s our bodies are buried, it’s Jaeger-LeCoultre. Because the oldest watch producer within the area, it’s been there for 189 years, which equates to plenty of change, even within the slow-moving world of watches. It’s also one of many few remaining corporations to design, make, and assemble almost 100% of its motion elements in addition to its instances and dials. In reality, there may be little or no this Le Sentier-based manufacture doesn’t do.
Charles-Antoine LeCoultre

Charles-Antoine LeCoultre and his Workshop in Le Sentier, Switzerland
However earlier than there was Jaeger-LeCoultre, there was simply LeCoultre – Charles-Antoine, an apprenticed blacksmith whose job concerned hardening and heat-treating metal elements to be used in pocket watches. His dealing with of those items gave him a singular perception into the challenges watchmakers confronted, so he stared designing and constructing equipment to assist produce pars extra effectively.
By 1833, Charles-Antoine had arrange his personal store the place he garnered plaudits for his Millionmètre machine, which measured to a decision to 1/1000 of a millimetre. He subsequently began making full watch actions, inventing a crown-operated winding system that negated the necessity for a key. The following step was to remodel the store right into a watchmaking plant, which Charles-Antoine did together with his three sons, Elie, Paul, and Benjamin.
It was the primary within the Vallée; steam-engine powered and with electrical lights. It grew to become so profitable that, by the top of the 19h century, it employed 500 individuals and was the go-to for sophisticated actions, akin to repeaters and perpetual calendars.
Charles-Antoine LeCoultre Creates With Edmond Jaeger

Jaeger-LeCoultre Atmos Clock
It was warfare, particularly WWI, that introduced LeCoultre into contact with Paris-based instrument maker Edmond Jaeger and, when the wristwatch market boomed after the warfare, the 2 had been able, in 1925, to launch a co-branded watch with a dual-level baguette motion that might be simply changed in minutes and repaired later.
Jaeger additionally introduced Parisian aptitude to the Le Sentier marque. His Paris connections meant the designs took on a extra creative bent, whereas the supplies modified as nicely, with chrome steel for instances and sapphire crystal overlaying the dials.
The following few years had been creatively wealthy for Jaeger and LeCoultre. 1928 noticed the launch of Jaeger’s Atmos clock, which makes use of temperature variations to generate power, and in 1929 the duo unveiled the world’s smallest mechanical motion, the hand-wound Calibre 101. A fragile design that might, 24 years later, be seen on the wrist of Elizbeth II at her coronation. However 1930 was the large yr – it was the yr the Reverso was launched.
The Iconic Jaeger-LeCoultre Reverso

A gift day Jaeger-LeCoultre Reverso, the design has stood the check of time
The Reverso has grow to be just like the Submariner, or the Royal Oak – no model title vital and an iconic silhouette. It was born on the polo fields of India after a Swiss watch vendor, César de Trey, was requested, by a polo participant, to design a watch robust sufficient to resist a collision with a polo ball. De Trey approached Jacques-David LeCoultre, Charles-Antoine’s grandson, to make the motion and requested Jaeger for the case.
It was French designer and engineer Rene Alfred Chauvot who got here up with the “slip and flip” mechanism and historical past was made. Regardless of being an on the spot success, with watches able to put on simply 9 months after patents had been awarded, WWII killed off the Reverso.
It was solely resurrected once more within the Seventies, because of the tenacity and insistence of Jaeger-LeCoultre’s Italian distributor Giorgio Corvo who was canny sufficient to purchase the final 200 Reversos available on the market.
Innovation Continues

A Restricted Version remake of the magnetically shielded Jaeger-LeCoultre Geophysic 1958

It launched a self-winding motion, devised an influence reserve indicator, created the Memovox alarm wristwatch, and the magnetically shielded Geophysic. It did become involved with quartz motion improvement as a shareholder of CEH (Centre Electronique Horloger) the place the Beta21 originated. Jaeger-LeCoultre introduced out a disc calendar quartz design with a modified Girard-Perregaux calibre, however it nonetheless continued to develop mechanical calibres alongside.
After being purchased, together with IWC, by German automobile instrument maker VDO in 1978, it was acquired by Richemont in 2000. And that’s when the resurrection of the Reverso actually started. Realising its iconic potential, Richemont put it entrance and centre, taking that rectangular case as a base and a platform for experimentation.
Since then, this immediately recognisable elongated rectangle has been given a tourbillon and a platinum case (not precisely polo-pitch fodder), been given a dial on each side powered by a single motion and referred to as DuoFace; had chronographs and minute repeaters added to its compact type.
After which in 2021, it entered Jaeger-LeCoultre’s Hybris Mechanic line of extraordinarily sophisticated watches because the Hybris Mechanica Calibre 185 Quadriptyque. It is a watch with a jaw-dropping 4 dials and 11 issues, together with a flying tourbillon, minute repeater, and one dial devoted to exhibiting the three totally different variations of the lunar month.
There’s the synondic – the period of time from one new moon to the following, often rounded up as 29.5 days. Subsequent is the draconic, which takes under consideration the slight incline of the aircraft of the elliptic of the Moon’s path across the Earth, 5.14º, and the north and south Nodes the place the moon’s orbit and the elliptic’s aircraft intersect. It equates the lunar month as being 27 days, 5 hours, 5 minutes, and 35.8 seconds, with the Nodes rotation within the sky taking 18.6 years to finish.
The third show is for the Anomalistic cycle. Given the Moon’s orbit is elliptical it has some extent furthest from the Earth, the apogee, and some extent nearest, perigee; the road between the 2 being the most important axis of the orbit. Apsides is the collective time period for the apogee and perigee and the Anomalistic cycle is the size of time for the Moon to return to an apsis, which is 27 days, 13 hours, 18 minutes and 33.2 seconds.
And this all works through mechanics. Difficult doesn’t even being to cowl it.

Every thing continues to be made and assembled in Le Sentier, bar the sapphire crystal and straps, and every watch is subjected to a collection of six exacting checks, akin to water, temperature, shock, and magnetic resistance. These checks are achieved over six weeks, or 1,000 hours, as a part of Jaeger-LeCoultre’s “1,000 Hours Management” verification course of the model arrange in 1992.
