Our tourbillon ensures highest rate accuracy. 1815 TOURBILLON The tourbillon is one of the most amazing inventions in watchmaking. It neutralises the effect of gravity to which the oscillator of a mechanical timepiece is exposed and thus increases its rate accuracy. To benefit from the accuracy gain, the watch must be settable with equal precision. However, this proved to be a horological problem that remained unsolved for over 200 years. In 2008, Lange finally presented the solution: the patented stop-seconds mechanism for the tourbillon made it possible to precisely halt and set
Now you can also set it with absolute precision. Tourbillon with stop-seconds and ZERO-RESET mechanism a watch endowed with this complication. Now, the 1815 Tourbillon takes this development a step further: thanks to the integration of the Zero-Reset function, the seconds hand jumps to the zero position when the watch is stopped. This allows the minute hand to be exactly positioned and the watch to be restarted to the second. The precise interaction of the mechanisms is rounded out with a balance spring crafted by Lange. It is individually customised to each calibre – in the interest of superb precision. www.alange-soehne.com You are cordially invited to discover the collection at: A.
