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 ATUM Pure High Art. From the outside, the ATUM Pure High Art is nearly unchanged. The steel case underscores the technical nature of the model family. Its dial is endowed with a fine brushed texture and is lacquered in white, grey, or blue. Burnished chamfers on the seconds dial and along the applied markers amplify the sporty nature of thewatch. With their straight edges and broad chamfers, the lancet-shaped hands match the marker style. They are hand sculpted from stainless steel, a modern material that retains its toughness after tempering. After their openings are filled with white “Hy-Ceram”, the hands are meticulously polished to attain their final look.
