Made to commemorate the 20th anniversary of the launch of the Lange 1 model, the present reference 101.062 stands out as a testament of the exceptional leadership and guidance Walter Lange and Günter Blümlein left since the launch of their first collection in 1994. Featuring what are now considered as the four foundational models: the Lange 1, Arkade, Saxonia, and Tourbillon Pour le Mérite, the debut collection marked the establishment of a new design language, particularly evident in the dial design and movement construction.

Cased in platinum and featuring a stunning black guilloché dial, the present Lange 1 "20th Anniversary" showcases an interesting and highly rare feature, the black date indication. Reserved exclusively for the brand's rarest and most limited models, the timepiece was limited to just 20 examples with the present example being number 19.

Originally presented as a set with a diamond-set Little Lange 1, also available in the auction catalog in the following lot number 26, the timepieces come with a special numbered box which will be offered without reserve for an esteemed collector who will buy both timepiece and wishes to reunited them in a box together.

This timepiece is furthermore preserved in excellent condition with crisp hallmarks, deep engravings, along with its leather wallet and undated guarantee & service booklet.
