–
A Glashütte pocket watch in near mint condition, sold on December 9th, 1883 to company Dürrstein & Co., Dresden for 350 Marks – manufactured in quality 1A – with original box and Lange extract from the archives.
The watch is fitted with a particularly rare protection cap for the crown, which is integrated in the bow. This prevents accidental adjustment of the hands by pulling the crown, because with this model, the time is still adjusted by means of a setting pin.
