Early A. Lange & Söhne Lange 1s can be considered to be as collectable as first edition Porsches. Unconventional and virtually unchanged in terms of design for more than 25 years, its aura perfectly encapsulates Bauhaus artistic movement of the early 1930's with elegance and tradition.

First generation models, like the present example, were cased at 38.5mm in diameter, rendering them extremely comfortable and pleasant on the wrist. Furthermore, pre 1996 models can be easily identifiable by a closed solid caseback, as one can notice from this timepiece. Exceptionally, the present example comes with an additional sapphire crystal caseback which was requested by the original owner to be able to witness the beautify of the in-house manual winding caliber L901.0. Visually striking and superbly finished, the movement features blued screws, gold chatons, Glashütte ribbing and A. Lange & Söhne's signature hand-engraved balance cock.

The present Lange 1 reference 101.005 in platinum, is part of the original historical series featuring a solid caseback however, is exceptionally accompanied by an additional sapphire caseback requested by the original owner. In excellent overall condition, with its sleek design, superb craftsmanship, the present Lange 1 takes us back to a time where horological history was made.
