A. Lange & Söhne changed horological history when the brand was re-established in 1990 following the fall of the soviet union. It was in 1994, under the helm of Walter Lange and Günter Blümlein, that the very first collection was launched, comprising of four foundational models: the Lange 1, Arkade, Saxonia, and Tourbillon Pour le Mérite. It was immediately apparent from the four models that a new design language was established, most notably in the dial design and movement construction. Inspired by the five-Minute Clock of the Semper Opera House in Dresden, A. Lange & Söhne created the Outsize Date complication which would be the basis of many Lange models to come, but most notably first seen on the Lange 1 and eventually spawning offspring such as the Lange 1 Timezone, Lange 1 Lumen, Lange 1 Moon Phase and so forth. Other unorthodox and creative decisions included an off-centre dial layout featuring hours, minutes, seconds, along with a power reserve indicator, without any of these indications overlapping.

The present watch, a Lange 1 reference 101.062 cased in platinum and featuring a stunning black guilloché dial was made to celebrate the 20th anniversary of the launch of the Lange 1 model. An extremely rare feature is the black date indication - used exclusively by the brand for their rarest and most limited models. The model was made in 20 examples, with the present being 10.

The present watch was originally presented as a set with a diamond-set Little Lange 1, which is also available in the auction catalog as the following lot, as well as a special numbered box which is offered without reserve, for someone who will buy both timepieces and want to reunited them in a box together. So rare is this edition that it marks the very first time that both watches within the same edition (a Lange 1 and Little Lange 1) are available at public auction, along with the special limited edition box.

This timepiece is furthermore preserved in excellent condition with crisp hallmarks, deep engravings, along with its leather wallet, Lange 1 booklet and Garantie & Service dated December 24, 2014.
