Moritz Grossmann Announces the New TEFNUT Silver-Plated by Friction

Last Updated: November 24, 2023Tags: ,

The latest TEFNUT model showcases the pinnacle of traditional craftsmanship. This model is a testament to Moritz Grossmann’s commitment to simplicity and elegance, featuring a design that exudes understated luxury and is meticulously handcrafted from premium materials. Every element, no matter how minor, is refined to perfection. This iteration of the TEFNUT range stands out with its dial, meticulously hand-silver-plated using a friction method, lending it a confident and graceful look.

All timepieces from the Moritz Grossmann workshop in Glashütte share a common allure, captivating from every angle. The dial and movement of the TEFNUT silver-plated by friction model, with its high-quality German craftsmanship and attention to unique details, are no exception. This model is the new benchmark for the Tefnut collection, characterized by its distinct, shimmering dial that exemplifies simplicity and refined elegance.

The dial’s texture is achieved through a historic 19th-century technique known as grain or silver-plating by friction. Applied manually in the Grossmann studios, a special paste of silver powder, salt, cream of tartar, and water is brushed onto the dial and worked until a fine-grain texture emerges, followed by a thorough final polish. This intricate process, requiring skilled expertise, creates a captivating play of light and shadow, enhancing the TEFNUT’s charm.

The dial’s design features contrasting black elements, including numerals, lettering, and the historic’ M. Grossmann.’ logo, all set in black lacquer and kiln-fired. The silver powder doesn’t adhere to the lacquered areas, creating a striking contrast. The hands, crafted in brown-violet and annealed, complement the dial with their delicately curved and finely pointed design.

The TEFNUT silver-plated by friction is versatile in size, with a 39-millimetre diameter case suitable for any wrist. It comes in elegant rose gold or bold stainless steel, featuring a sleek, comfortable design. The case’s distinctive aspects, such as the grooved crown, slender lugs, and hand-sewn alligator leather straps, enhance its sophistication.

Inside, the hand-wound calibre 102.1 adds to the watch’s allure. This mechanism is just four millimetres high with its well-orchestrated design and typical Grossmann features. It features a traditional pillar movement with distinctive Grossmann traits like the stepped balance cock and raised chatons, showcasing the brand’s signature Glashütte style with hand-engraved pieces and white sapphires set in gold chatons.
