Moritz Grossmann TEFNUT Silver-Plated by Friction Gold
The year 2026 marks a defining milestone for Moritz Grossmann, celebrating 200 years since the birth of its visionary founder. The TEFNUT Silver-Plated by Friction Gold is released as part of this significant anniversary, bringing together the legacy of 19th-century watchmaking with the refined execution of modern independent horology. Rather than recreating the past, this piece reflects an ongoing evolution of Grossmann’s ideas, expressed through contemporary craftsmanship and technical precision.
At first glance, the TEFNUT embodies restraint. Its design is deliberately minimal, allowing its most intricate details to reveal themselves gradually. The dial is its defining feature, finished using the traditional and rarely mastered technique of silver-plating by friction. This process, carried out entirely by hand, produces a soft, velvety surface with a fine granular texture. The result is a dial that shifts subtly under changing light, offering depth and character that cannot be replicated through industrial methods.
The contrast of fresh green numerals and lettering against the silvered surface introduces a modern element without compromising the watch’s classical identity. The historic “M. Grossmann” signature, presented in its original 1875 form, reinforces the connection to the brand’s heritage. Completing the dial are finely crafted lance-shaped hands in polished gold, shaped and finished by hand through a meticulous multi-stage process that reflects the highest level of artisanal skill.
Encasing the dial is a 750/000 yellow gold case, marking the first time the TEFNUT has been offered in this material. Its slim profile and balanced proportions are made possible by the refined calibre 102.1, a hand-wound movement measuring just a few millimetres in height. The case design complements the understated nature of the watch while offering a warm, traditional presence on the wrist.
Turning the watch over reveals the full depth of Moritz Grossmann’s watchmaking philosophy. The calibre 102.1 is constructed as a classic pillar movement, featuring a 3/5 plate architecture and finely finished components throughout. Details such as the stepped balance cock, Grossmann micrometer screw, and raised gold chatons speak directly to historical Glashütte traditions, while the finishing techniques elevate the movement into a distinctly modern context.
As a final tribute to the anniversary, the balance cock is engraved with “1826,” referencing the birth year of Moritz Grossmann. This subtle detail connects the wearer directly to the legacy of one of Germany’s most important horological figures. The TEFNUT Silver-Plated by Friction Gold stands as a refined and thoughtful expression of that legacy, created for collectors who value authenticity, craftsmanship, and enduring design.
