Some weeks ago we were invited to visit the Jaeger-LeCoultre manufacture, in order to see the Grande Complication Workshops during a factory tour.

JLC-06335After arriving in Le Sentier, where we will spend the day at the Jaeger-LeCoultre manufactory, we are welcomed by Marina Greene at the Lounge of the ‘Maison d’Antoine’. From here we have a great view over the Vallée de Joux.

Jaeger-LeCoultre manufacture Grande Complication presentation

Our program begins at the Grande Complication Work shop where 12 watchmakers are working on highly complicated watches. Here, master watchmaker Christian Laurent, presents us with the Grande Complication Collection and an in-depth explanation of the Gyrotourbillon models.

Please note that some of the watches shown are unfinished prototypes and do not represent the final high quality finish you can expect on these high-end watches.

Jaeger-LeCoultre presented their first gyrotourbillon around 2005. Today there are 4 models featuring this complication. The 2nd gyrotourbillon, in a Reverso case was made in 2009. Beating at 4 hz and using a cylindrical spiral (best seen in the second photo) for the first time. This helps in getting better accuracy when the power reserve is getting low. In total there are about 100 parts in the gyrotourbillon cage alone. Weighing roughly  0.3 (!) grams in total.

Talking about the Reverso Gyrotourbillon version 2 and 4. Where the first was quite thick and big on the wrist, the new version that was presented during the 2016 SIHH is much compacter.

We continue our visit at the ‘Métiers Rares‘ workshop. Stefan Richi, chef d’atelier, explains us the various crafts and techniques the artisans are working on. Back in the days each specialty like enameling and gem-setting had their own workshop. The Jaeger-LeCoultre manufactore has been changed over the last couple of years and the workshops of different expertises have merged, thus giving them more interaction and collaboration as the craftsmen and women, or artisans as you please, work side by side now and get the freedom to try other skills. For instance and as a result of this, the artisans came up with a way to combine engraving and enameling.

In the middle of the new atelier, divided by glass walls there is a small presentation room with a video table. At the push of a button we can see what the artisans are doing on the screen.

Jaeger-LeCoultre manufacture Artisans Workshop

Just as if we are looking through the microscopes the artisans use for their work. It’s incredible to see how precise a miniature enamel painting is being created with many details, the custom engraving of a case back or the diamond setting on a dial. Given the incredible small dimensions it’s hard to imagine it’s actually done by hand.

On the other side of the workshop there are recently acquired, and fully restored guilloché machine from the past. Combined with modern microscopes these are now used for the decoration of various watch parts like the dial of the new Reverso Gyrotourbillon.

After this impressive trip down memory lane and our lunch, one of the master watch makers gives a demonstration of the Reverso case assembly. With all our eyes on his fingers he shows us how to take apart the case of the Reverso. For this demonstration he uses a new model from the collection presented at the 2016 SIHH.

Due to the privacy of personnel we cannot publish the photos taken at the watchmakers doing the assembly of the watches, so we continue our tour at the Atmos workshop. Here the famous desktop clocks are made and maintained. Powered just by the pressure of air the Atmos clock is a sample of extraordinary clock making.

With a visit of the heritage gallery our trip slowly comes to an end. Besides several watches (sorry, photos not allowed) that are on display there is a huge glass wall that contains almost all the movements Jaeger-LeCoultre has produced through the years. Time to say goodbye and find our way home again after an impressive visit.

We would like to thank Jaeger-LeCoultre for their hospitality and invitation for this tour.
