oritz Grossmann celebrates the 200th birthday of its founder with the launch of the TEFNUT 36 Silver-Plated by Friction Turquoise Blue, a timepiece limited to just 12 pieces worldwide. This special anniversary edition combines traditional 19th-century craftsmanship with a modern aesthetic, paying homage to the visionary watchmaker, scientist, and founder of the German Watchmaking School. The manufactory in Glashütte continues to honor this rich heritage by blending historical techniques with contemporary design.
The dial of the watch is crafted using a meticulous silver-plating by friction technique, also known as silver-plating by grit, which is executed entirely by hand through multiple complex steps involving silver powder, salt, tartar, and water. This traditional process imparts a velvety, matte structure with remarkable optical depth, further enhanced by a unique green-tinged blue hue that shifts dynamically depending on the angle and lighting. Contrasting the textured surface are engraved Roman numerals lacquered in blue, alongside the historic 1875 'M. Grossmann' logo, scale markers, and manually crafted steel hands annealed to a vibrant blue hue.
Housed in a slender and expressive 36-millimeter stainless steel case with a flat profile, the watch is designed to offer exceptional comfort and elegance on any wrist. It is complemented by a hand-stitched grey kudu leather strap featuring a pin buckle in stainless steel. Inside ticks the manufacture calibre 102.1, a hand-wound mechanical movement measuring just 3.45 millimeters in thickness, featuring a pillar movement architecture, a three-fifths plate, a stepped balance cock with a Grossmann micrometer screw, and a special '1826' anniversary engraving.
