A historic engraving technique is being given a new lease of life to mark Moritz Grossmann's anniversary on 11 November 2021. Finished using the eponymous tremblage engraving technique, the TREMBLAGE anniversary model elegantly combines vintage style with the finest mechanics. The timepiece is available in rose gold (shown) and stainless steel, with a choice of straps and buckles.

Ref. MG-003290

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.
