With these versions of the ATUM Pure, initials or names serve as elements of extraordinary dial designs. What they all share is the variable transparency of the dial insert that affords a more or less detailed view of the inner life of the watch. Watch enthusiasts have kept an eye on the calibre 201.1 with the Pure-Classic finish. Even a casual glance reveals the fascinating formal and colour details of this calibre that has been specially conceived for the steel version.

The focus is on the dial insert that accentuates the prominent face of the watch. All dial versions are crafted in the manufacture based on proprietary motifs. Depending on the variation, the look on the wrist is modern, technical, or creative. The individual limited editions enhance the allure of the ATUM Pure X models … To be continued.


The case and the dial

The version H

The case and the dial

The unchanged case of the ATUM Pure stands out with its slender bezel. The crown and pusher are telltale signs of the characteristic winding mechanism that also shines through the dial. A black alligator strap is combined with the polished stainless steel and stainless steel DLC dianoir cases. The contrast colour of the carefully stitched seam matches the respective colour of the HyCeram fillings in the dial.

The six-part dial, designed and crafted in-house, presents itself with a significantly different looks. Crisp scales are among its salient features. The minute ring accommodates eight prominent hour markers, while the modern Arabic numerals 9, 12, and 3 enhance the hour ring. The seconds, the logo bridge, and the hand bushings complement the lineup of details.

Both lancet-shaped hands are manually crafted from stainless steel and like the hour markers are filled with HyCeram. The four HyCeram colours — white, blue, green, and orange — endow the watches with casual elegance, cool perfection, or dynamic radiance.

The version H

Die ATUM Pure Hands. The hands form a dial insert for which — using all hand shapes crafted in the manufacture — an all-in-one composition is orchestrated. Once the fine contours have been traced with electrical discharge machining, the dial insert is mirror-polished and glistens in a vivid contrast against the movement with the Pure-Classic finish.
