Tefnut, Rose Gold
The TEFNUT captures the essence of Moritz Grossmann watchmaking: refined simplicity, uncompromising quality, and timeless elegance. Crafted with high-grade materials and finished entirely by hand, it represents pure understatement at its most luxurious.
Inside its gracefully proportioned case lies a reimagined mechanical calibre—slender yet powerful—distinguished by its linear-symmetric architecture and the uniquely modified cut of the 3/5 plate. Every detail reflects the precision and artistry that define Grossmann’s manufactory.
The latest evolution, the TEFNUT Silver-Plated by Friction, introduces a new dial with an artisanal, hand-applied finish. Its subtle texture and luminous presence elevate the watch’s character, giving it a confident and contemporary edge while preserving its classical DNA.
The TEFNUT is more than a timepiece—it’s a testament to horological heritage, modernized for today’s discerning collector.
