Moritz Grossmann TEFNUT – Silver-Plated by Friction
The TEFNUT embodies the timeless virtues of the Moritz Grossmann manufactory: refined simplicity, handcrafted excellence, and an elegance rooted in understatement.
Within its gracefully balanced case lies a reimagined movement of striking finesse. Slim in profile yet rich in detail, the calibre carries the hallmarks of Grossmann craftsmanship while standing apart with its distinctive linear-symmetric architecture—instantly recognizable through the uniquely cut 3/5 plate.
This latest interpretation introduces a fresh aesthetic: a dial hand silver-plated by friction, a traditional artisanal technique that lends the watch a confident, radiant presence. The result is a timepiece that marries classic watchmaking artistry with modern sophistication—an enduring expression of elegance on the wrist.
