One-minute tourbillon with stop seconds, black enamelled dial and artisanal finishes, enclosed by a 38.5-millimetre platinum case – these are the salient features of the Lange 1 Tourbillon Handwerkskunst.

The black enamelled main dial  bears mirror-polished hour markers as well as matching hands in rhodiumed gold. The tourbillon cock, finished with the challenging specular polishing technique, is one of the key style elements of this watch. The black solid-silver subsidiary dial for the seconds is slightly recessed into the main dial. The contour of the aperture for the tourbillon has polished chamfers. The numerals of the Lange outsize date are grey on a black background.

The lavish decorations of the calibre L961.3 manufacture movement deserve the attribute “Handwerkskunst” in every respect. The solarised three-quarter plate made of untreated German silver has generous cutouts that reveal the identically decorated twin mainspring barrel. The tourbillon bridge, crown-wheel and intermediate-wheel cocks are engraved with a technique that sculpts the motifs out of the material. Seven screwed gold chatons as well as two diamond endstone bearings for the tourbillon constitute the finishing touches. The diamonds are traditional hallmarks that Ferdinand Adolph Lange once introduced to highlight the premium quality of his pocket watches.

In 2008, A. Lange & Söhne’s product developers succeeded for the first time in reliably immobilising the balance wheel inside the rotating tourbillon cage. Finally, timepieces with tourbillons could be stopped and set with one-second accuracy. The patented stop-seconds mechanism is also integrated in the Lange 1 Tourbillon Handwerkskunst.

This special edition limited to 20 watches is fitted with a black hand-stitched crocodile strap, equipped with a Lange deployant buckle in platinum.
