German watch manufacture Moritz 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 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 the watch. 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.
The calibre 100.1 can be admired through the ample, non-reflective sapphire-crystal display back. Subtly proportioned components in untreated German silver with different types of finissage constitute the individual levels of the pillar movement. The signature is hand-engraved into the characteristic 2/3 plate decorated with wide horizontal ribbing. The circular cutout of the plate reveals the Grossmann balance. It is carried by the cantilevered, hand- engraved balance cock with the typical micrometer screw.
The Grossmann winder with pusher features are fined handsetting mechanism that eliminates two possible error sources: the ingress of particles into the case while the hands are being set and the unintentional alteration of the hand positions while the crown is being pushed home again. The ATUM Pure High Art also embodies all the hallmarks and underlying values of a classically crafted timepiece signed MORITZ GROSSMANN GLASHÜTTEI/SA.
The special edition of the ATUM Pure High Art comes with white, grey, and blue dials. All three versions of this edition are limited 15-watch editions within the 150 watch limitation per dial version of the ATUM Pure.
