A. Lange & Söhne releases limited-edition tourbillon watch

A. Lange & Söhne celebrates the 20th birthday of its brand icon with a limited special edition - the Lange 1 Tourbillon Handwerkskunst. Limited to 20 pieces, the watch comes in a platinum case and features a black enamelled main dial, gracefully decorated by mirror-polished hour markers and rhodiumed gold hands. The sub-dial, slightly recessed into the main dial, is made of solid silver. The tourbillon clock, finished with the challenging specular polishing technique, showcases the brand's craftsmanship.

The solarised three-quarter plate made of untreated German silver has cutouts that reveal the identically decorated twin mainspring barrel.

Seven screwed gold chatons and two diamond end-stone bearings for the tourbillon constitute the finishing touches.
