The silver-coloured dial with relief engraving on the TEFNUT Grand Dame was specially handcrafted according to the design of an original ladies’ pocket watch by Moritz Grossmann from the 19th century. This exceptionally beautiful pocket watch was given by the old master and watch pioneer to his second wife during his lifetime.

The outer dial is adorned with a handmade shimmering golden ring in a floral pattern. The inner ring around the diamond shimmering hand sockets is surrounded by fine gold-plated flowers.
