Grossmann‘s watchmakers fulfilled a long-standing wish when they created the innovative winding mechanism for the TEFNUT. The quest for a robust alternative to the conventional crown winder ended with an exceptionally original solution: The Grossmann strap winder makes it possible to wind the watch hands down, so to speak, with just a few turns of the strap attachment at 6 o‘clock.
To enable this remarkable feat, the calibre 102.2 was extensively reworked and the exterior form of the TEFNUT modified. A first glance is enough to see that the Grossmann strap winder has strikingly different strap attachment points and an unusual setting crown position. With its two distinctive versions — „Classic“, and „Fancy“ — in rose-gold or white-gold cases, the TEFNUT Twist stands out prominently in terms of both appearance and mechanical ingenuity.
