SIHH 2019: Jaeger-LeCoultre with a high precision tourbillon
Master Grande Tradition Gyrotourbillon Westminster Perpétuel by Jaeger-LeCoultre
Further advancing the art of multi-axis tourbillons, the Master Grande Tradition Gyrotourbillon Westminster Perpétuel features a tourbillon that is significantly smaller than those in the preceding Gyrotourbillon timepieces. As a rule, reducing the size of a mechanism also reduces its error tolerance, which is why successful miniaturization efforts are so highly valued and
complex. In creating a smaller tourbillon, Jaeger-LeCoultre has created a truly wearable Gyrotourbillon, bringing high complication out of the watch safe and onto the wrist for everyday enjoyment. The Westminster chime is familiar to everyone as the famous melody of the Big Ben clock at the Palace of Westminster in London.
