In keeping with the strict form vocabulary of the model family, the TEFNUT 36 represents a smaller variation featuring an elegant case with a diameter of 36 mm. On account of its enhanced comfort on the wrist, this universal format is convincing for male and female watch enthusiasts alike. The gently curved lugs also hug the wrist. Their tapered chamfers form a seamless transition to the strap.
The calibre 102.0 movement was newly conceived from the bottom up. With a diameter of only 26 mm and a height just under 4 mm, it is distinctly smaller and flatter than previous Moritz Grossmann movements.
With the straight cut of the train bridge and the newly configured going train, the calibre looks very well organised and showcases the deliberately arranged inner life of the watch. The ARCAP alloy of the wheels contrasts well against the German-silver movement elements. The large mainspring barrel suspended between bearings on both sides is an eye-catcher as well. Despite its compact dimensions, the classic pillar movement with the main plate and the 3/5 plate features all Grossmann hallmarks such as the cantilevered balance cock with the Grossmann micrometer screw, the raised chatons, the separately removable winder module, and the mass-optimised Grossmann balance. Because of the smaller diameter of the balance, the new calibre generation breathes at a frequency of 21,600 semi-oscillations per hour and assures dependable rate stability.
