Grossmann is introducing a special version of the ATUM Pure in a stainless steel case with the calibre 100.1 movement featuring the precious High-Artistic Finish – the HIGH ART. From the outside, the HIGH ART is nearly unchanged.
The steel case underscores the technical nature of the model family. The HIGH ART also embodies all the hallmarks and underlying values of a classically crafted timepiece signed MORITZ GROSSMANN GLASHÜTTE I/SA.
The Dial
The HIGH ART amplifies the appeal of classic precision measuring instruments. Its single-part dial has a fine brushed texture coated with lacquers of different colours to enhance the subtle metallic effect. The recessed seconds subdial is sharply contoured with a burnished chamfer.
The applied hour markers are particularly plastic and prominent. They contrast brilliantly against the white, grey, and blue dial variants.
The winding crown and the pusher
The gently curved form and the tapered chamfer of the strap lugs enhances the eloquent silhouette of the case.
Aesthetic and functional — the circumferential groove makes it easy to pull out the crown. The pusher for the new handsetting train is set directly below the winding crown.
The hands
Special hands are manually crafted in-house for the HIGH ART. Designed to match the markers, the lancet-style hands feature straight edges and broad chamfers that contribute to their slender yet corporeal looks.
They are made of stainless steel that retains its remarkable toughness after tempering. To optimise legibility, pockets are worked into the hands and then filled with white “Hy- Ceram“, a compound that consists of ceramic powder and resin. Then, the tips of the hands are precision ground. Finally, they are polished to a mirror gloss, including the white fillings.
