Moritz Grossmann TEFNUT Sleeping Beauty Diamonds
Reference: MG-001769
A further jewellery watch for the TEFNUT family was the result of a joint venture between two worlds: an imaginative motif created by award-winning designer Michael Koh from Singapore paired with schönstes deutsches Handwerk of the Grossmann manufacture in Glashütte. Michael Koh‘s passion is exceptional precious stones that he showcases in unique ways. His creations tell mystical stories — the TEFNUT Sleeping Beauty leads us to the secretive world of the moon.
Despite its grace and compact size with a diameter of 26 mm and a height of merely 4 mm, the modified calibre 102.0 sets the stage for a fairy-tale scene. The classic pillar movement with the 3/5 plate embodies characteristic Grossmann calibre elements such as the cantilevered balance cock, the Grossmann poising screws, the raised chatons, the separately removable winder module, and the mass-optimised Grossmann balance.
