Reduced to perfection

ATUM Pure Skull


As was the case with the ATUM Pure M and L, the face of the watch features two prominently designed rings for the minute and hour indications.

In place of the “Mesh” and “Long Hole” dial inserts, the ATUM Pure Skull showcases a stylised skull in its centre.


The skull

The hands

The skull

The skull is milled and wire-cut with electrical discharge machines in the manufacture, its surface polished or sandblasted to match the case, and then assembled with the remaining dial elements. This individualised manufacturing approach lends itself to dials with other popular motifs or heraldic symbols.

The hands

Special hands are manually crafted in-house for the ATUM Pure Skull. 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 black “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.
