Moritz Grossmann ATUM Enamel Limited Edition

In all of its versions, the ATUM line embodies pure watchmaking artistry. Each model presents a special and inimitable accent. To welcome the dawn of 2017, Grossmann is presenting the ATUM Enamel with an extravagant dial design.

The two-part dial has a white enamel face. The scales and numerals are printed in black. The Roman numeral XII is printed in royal blue to match the strap. Enameled dials were common hallmarks of precious pocket watches and remain very rare features of wristwatches. Connoisseurs appreciate the unique gloss of enamel that cannot be imitated by any lacquering method. The hands are manually crafted and annealed to a rare brown-violet hue.

The ATUM Enamel is endowed with the manufacture calibre 100.1 with the High-Artistic Finish. The Grossmann winder with pusher, the Grossmann balance, the modified Glashütte stopwork, the beat adjustment system with an index tail, and the Grossmann poising screw are the key elements of the pillar movement with the prominent 2/3 plate.

The ATUM Enamel is presented rose-gold and white-gold versions. Both versions come with a white-enameled dial printed in black except for the XII which is printed in blue, and a blue alligator strap. The ATUM Enamel is being introduced in a limited edition of 25 watches per case version.
