US$ 200,000-300,000
EUR 147,000-223,000
With Jaeger-LeCoultre presentation box, certificate, magnifier and product literature.
At the heart of a fascinating collaboration between engineering and design, is the Jaeger-LeCoultre Calibre 177 which features the world's first spherical multi-axis tourbillon constructed of two carriages wherein the external cage rotates every 60 seconds whilst the internal one that supports the balance wheel, spiral and escapement revolves almost every 24 seconds, thus completing 2.5 turns in a minute. This exceptional complication permanently compensates for the rate of gravity-related errors in all positions.
