ATUM Backpage Platinum

A showcase for the art of Grossmann watchmaking

Schönstes deutsches Handwerk

The renowned German watchmaker Moritz Grossmann celebrates its tenth anniversary in November. To mark this special occasion the independent watchmaker from Glashütte is pleased to reveal its eleventh special model, the ATUM Backpage Platinum. This platinum single edition piece offers a showcase for Grossmann’s beautiful watchmaking art.

With the exception of the delicate minute scale on the rim of the watch face the dial is completely exposed enabling spectators to admire all the beautifully intricate details of the movement.

The ATUM Backpage Platinum‘s artistically handcrafted movement has been mirrored and shifted to the dial side by Moritz Grossmann’s master watchmakers. Thanks to an unex-pectedly large dial cut-out, the characteristic movement details such as Grossmann’s ba-lance wheel, a hand-engraved balance cock and three band snailings on the ratchet wheel can be fully observed while on the wrist.

Wide Glashütte stripes are applied to both sides of the movement and the Moritz Gross-mann logo is hand engraved on the dial side. Blue hands and blue screws, tempered in the manufactory, complete the elegant colour scheme of this extraordinary watch.

On the back of the movement, the winding and hand-setting mechanisms are openly in-tegrated into the train bridge and can be observed in their full functionality. Almost all parts in the movement are mirrored in order to guarantee their function even when moun-ted in the opposite position.

The Moritz Grossmann brand manufactures timepieces to the highest standard of crafts-manship under the motto ‘Schönstes deutsches Handwerk’ - The most beautiful German craftsmanship. The ATUM Backpage Platinum is offered with the calibre 107.0 in artistic hand finish as a single edition 1 of 1.

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