The German watchmaker, A. Lange & Söhne, have introduced a 100-pieces limited-edition of the 1815 TOURBILLON with a white enamel dial. 1815 TOURBILLON, released four years ago, was the first watch to combine the stop-seconds mechanism with the ZERO-RESET time setting feature which allowed it to be stopped and then set with one-second accuracy.

Traditional craftsmanship combines with modern micromechanics in the limited-edition variation of this precision timekeeping instrument. The large aperture at 6 o’clock alone provides a modest impression of its complexity: it reveals the one-minute tourbillon, suspended beneath a black polished bridge, in action. However, this tourbillon doesn’t just offset the influence of gravity.

The mechanical precision of the lavishly finished manufacture calibre L102.1 can be admired through the sapphire-crystal caseback. The exquisite movement decoration is crowned by a diamond endstone in a screwed gold chaton on the fourth-wheel bridge, which is adorned with a freehand engraving. The platinum caseback is numbered from 001/100 to 100/100 consecutively for the 100 pieces. The quest for historic authenticity stands out in details such as the separately printed and red-fired number 12. Blued-steel hands, Arabic numerals and a railway-track minute scale represent the classic personality synonymous with legendary nineteenth and twentieth-century pocket watches. The 1815 Tourbillon is equipped with a black hand-stitched alligator leather strap secured with a solid-platinum deployant buckle.
