ATUM Backpage Rose Gold

A showcase for the art of Grossmann watchmaking

Schönstes deutsches Handwerk

The independent Glashütte watchmaker Moritz Grossmann will celebrate its tenth anniversary in November. With its eighth special model, the ATUM Backpage in rose gold, the company offers a showcase for the beauty of Grossmann’s watchmaking art. With the exception of the fine, fully circumferential minute scale, the dial side is kept completely free. Thus all the details of the beautiful spectacle that is the movement can be admired even while reading the time.

On the ATUM Backpage Rose Gold, the watchmakers from Grossmann have shifted the calibre 107.0, mirrored in a High-Artistic Finish, to the dial side. Thanks to an unusually large dial cut-out, the characteristic movement details such as Grossmann’s balance wheel, hand-engraved balance cock and three band snailing on the ratchet wheel can be seen on the wrist. Wide Glashütte stripes are applied to both sides of the movement. The Moritz Grossmann logo is engraved by hand on the dial side. Brown hands tempered in the manufactory and brown-violet screws complete the elegant and warm-toned colour spectrum of this extraordinary watch.

On the back of the movement, the winding, hand setting and second mechanisms are openly integrated into the wheel bridge and can thus be observed for the first time in their full functionality. Almost all of its parts are mirrored in order to guarantee their function even when mounted in the opposite position while ensuring the position of the lever remains unchanged.

The Moritz Grossmann brand manufactures timepieces to the highest standard of craftsmanship under the motto “Schönstes deutsches Handwerk”. The ATUM Backpage Rose Gold is offered with the calibre 107.0 in a High-Artistic Finish as a single edition 1 of 1.

Moritz Grossman is working on something very special. Details regarding purchase options for the ATUM Backpage Rose Gold will be published in the coming weeks.

The BENU No. 1 in rose gold radiates individuality and unobtrusive elegance in its classic design; qualities that also characterise the uncrowned old master and the man who gave the company its name, Moritz Grossmann.

The BENU No. 1 is offered with the calibre 100.0 in the high artistic hand finish with the engraving 001/ 100.
