The TEFNUT Lady is the first Moritz Grossmann watch that combines horological class with feminine charisma. A radial guilloché pattern unfolds across its sub-lime mother-of-pearl dial. The origin of the rays at 6 o‘clock is a gold chaton with a glistening diamond. It underscores the gracefulness of this timepiece.

Two manually crafted hands in steel annealed to a brown-violet hue stand out with a delicately curved nodal shape and wispy contours. A gold bezel, option-ally set with 80 brilliant-cut diamonds, frames the elegant face of the watch. Its heart is the calibre 102.0 movement, a totally new development. Easily verifiable: This slender masterpiece proves that sparkling diamonds and technical brilliance are a perfect match.

 You can find more details about this product on our official Moritz Grossmann website.
