In 2014 Lange introduced the 1815 Tourbillon and like all its other creations, this timepiece is a beautiful piece of over engineering. The silver dial is inspiring in the simplicity of its minimalist design. It features a recessed center and elegant Arabic numerals paired with the firm’s signature blued hands. The extra-large opening of the dial allows an unobstructed view of the 13.2mm tourbillon that is held by a long faceted bridge crossing the lower part of the dial from 4 to 8 o’clock.

With the 1815 Tourbillon, A. Lange & Söhne has gone to the origins of this complication: accuracy and improved it by adding a hacking system with zero reset, meaning that once the crown is pulled out the movement stops and the seconds hand, placed on the tourbillon cage, snaps to zero allowing precise time adjustment of the watch.

The movement in all its Technicolor glory is pure Lange delight with its large Geneva waves (that the brand likes to call Glashütte waves), red rubies held within gold chatons secured by blued screws and a hand engraved balance cock. In a nod to traditional Saxon watchmaking the tourbillon is set within a diamond endstone.

Extremely crisp and offered in “like new” overall condition with no signs of use and wear, the present example in 18K pink gold from circa 2021 is offered with its full set of accessories.
