Reasons to Bid

A highly rare, collectible and fine Bauhaus-styled 14k yellow gold wristwatch of the famous German watch brand A. Lange & Söhne, founded in 1845. Produced circa 1941. Case made of 14k yellow gold, diameter 36mm, snap-fitting solid-gold caseback. Matte gilt dial signed “Lange Glashütte/Sa.”, slightly recessed small seconds sub-dial, blued steel stick-shaped hands, black printed Roman numerals and markings. Caliber Altus 10 1/2’’’, hand-wound, signed “Lange-Uhr Glashütte”. Functions – indication of time in hours and minutes, small seconds hand at 6 o’clock.

In the 1930s, Otto Lange, director of A. Lange & Söhne, launched the production wristwatch collection, all timepieces of which were signed as “Lange Glashütte/Sa.” or “Lange-Uhr Glashütte/Sa.” These were more accessible compared to A. Lange & Söhne’s high-end wristwatches of that period. In fact, Lange Glashütte/Sa. was a sub-brand of the world-renowned German brand name. The watches were powered by round or shaped calibers of Montres Altus, the Swiss movement-blank factory. The finishing of the calibers shows signs of high-quality workmanship, typical for Lange, including a blued Breguet hairspring, double spiral finishing (double solarisation) on the barrel ratchet wheel, a highly polished index lever and endstone cap, engraved and gold-plated inscriptions, fine chamfering work, Côtes de Genève decorated bridges, a perlage-embellished mainplate, finely finished screw-heads, and spherical polishing of pivots and pins. In particular, we would like to draw attention to the sharp internal corners with meticulous handwork shaping and polishing of the inner exterior and interior angles during bevelling, which are unthinkable in modern accessible watches. This is an extremely costly operation for a watch brand, where a lot of time and effort is required.
