Reduced to perfection.

Pure, the attribute of Grossmann‘s philosophy, also identifies the manufacture‘s steel models. Their hallmark is concentration.

Reduced to the essential functions, the steel case is the perfect reflection of its form. The ATUM model family stands for reduction in perfection.

The Dial

The Dial

The ATUM Pure 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 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

The hands

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