Moritz Grossmann TEFNUT 36 Enamel

To mark Moritz Grossmann’s tenth anniversary this November the independent watchmaker from Glashütte presents its sixth special model, the TEFNUT 36 Enamel from the TEFNUT line. The white enamel dial with delicate black Roman numerals of the TEFNUT 36 Enamel is framed by a white gold case. The sophisticated design of the watch resembles the elegant pocket watches Moritz Grossmann used to design and manufacture 150 years ago.

The Roman numerals with their contemporary serifs contrast the rich white enamel dial. Delicate black index points indicate the minutes. The small second at 7 o’clock is a stunning eye-catcher. The handcrafted brown-violet hands complete the classic look of this exquisite yet understated watch. The narrow bezel makes the watch look larger than its 36 mm diameter suggests.

With its calibre 102.0, the TEFNUT 36 Enamel has special features such as the cut of the three-fifths plate, the adjusting screw on the stepped balance cock and the brown violet tempered screws. Schönstes deutsches Handwerk can also be observed in the highly hand finished movement; the polished chamfers on the balance, the pallet cock and the balance cock. The TEFNUT 36 Enamel is offered with the calibre 102.0 in artistic hand finish as a single edition 1 of 1.
