Moritz Grossman TEFNUT Pure High Art

To mark Moritz Grossman’s tenth anniversary the independent watchmaker from Glashütte presents its fifth special model, the TEFNUT Pure High Art from the TEFNUT line. TEFNUT Pure High Art is a one-off piece that combines a chic contrasting canary yellow dial with a blackened stainless steel case.

In addition to its striking colour combination, the watch has an individual sporty character underlined by the artistically, hand-finished calibre 102.1 set in a steel case. The dominance of the bright yellow dial contrasts with the blackened case and the black leather wristband. On the dial, the Rhodium plated indexes and hands are polished for a high-gloss finish.

The TEFNUT model line is characterised by its particularly slim, flat case. Inside, the hand finished movement, polished gold chatons, wide Glashütte stripes, wheel train with polished bevels and hand-tempered screws in brown-violet can be admired through the crystal glass back of the watch. When combined, all these elements provide the calibre 102.1 its exquisite appearance. The TEFNUT Pure High Art is offered with the calibre 102.1 in high artistic hand finish as a single edition 1 of 1.
