There Are Tourbillons, Then There Tourbillons
Last month at the Salon International de la Haute Horlogerie (SIHH ) in Geneva, Jaeger-LeCoultre unveiled the Duomètre à Sphérotourbillon, a tourbillon wristwatch that is both visually and technically amazing.
In Geneva, I met with Stéphane Belmont, Marketing Director at Jaeger-LeCoultre, and we discussed the historic importance of a tourbillon in watchmaking. As you probably already know, the first tourbillon was developed by Abraham-Louis Breguet around 1795; its purpose was to counter the effects of gravity by mounting the escapement and balance wheel in a rotating cage, thus improving the accuracy of the timepiece's regulating organs. Back then, the tourbillon was used to increase the precision of a timepiece.
