The Tourbillon was developed to offset the disruptive effects of gravity on the balance wheel. It consists of a cage containing the balance, the pallet lever and the escape wheel. The balance & escapement rotate around their common axis going through all positions once a minute to average out the errors & thus resulting in a more accurate & consistent timekeeping. The intricate Tourbillon carriage is composed of 84 parts. The case material used is 18kt “HONEY” colored gold, exclusively developed for Lange & Sohne. The honey gold has a subtle warm hue to it & has a color somewhere between white gold & yellow gold. With a Vickers hardness of over 300, this gold is about twice as hard as other gold alloys, making it more scratch resistant.
