Material and surface form a fascinating liaison. German silver is an alloy of copper, nickel and zinc, among others, which is frequently used in historical watches and movements. Thanks to the surface treatment, this alloy produces a silver-like hue with an aesthetic vintage look. The three-dimensional appearance of the dial underscores the effect: The numerals of the hours and circular small seconds rise above the surface, as does the historic “M. Grossmann” logo from 1875, which goes back to Moritz Grossmann, the famous watchmaking pioneer who gave his name to the Glashütte manufactory.
Moritz Grossmann timepieces sell very quickly. If interested in one of these watches please reach out to Jeremy: Jeremy@osterjewelers.com to be updated with availability.
