A showcase for the art of Grossmann watchmaking

The renowned German watchmaker Moritz Grossmann celebrates its tenth anni-versary in November. To mark this special occasion the independent watchmaker from Glashütte is pleased to reveal its eighth special model, the BACKPAGE. This rose gold 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 BACKPAGE Rose Gold’s artistically handcrafted movement has been mirrored and shifted to the dial side by Moritz Grossmann’s master watchmakers. Thanks to an unexpectedly large dial cut-out, the characteristic movement details such as Grossmann’s balance 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 Grossmann logo is hand engraved on the dial side. Brown hands, tempered in the manufactory, and brown-violet screws complete the elegant and warm colour scheme 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 be observed for the first time in a Moritz Grossmann timepiece in their full functionality. Almost all parts if the movement are mirrored in order to guarantee their function even when mounted in the opposite position while the lever remains unchanged.

The Moritz Grossmann brand manufactures timepieces to the highest standard of craftsmanship under the motto ‘Schönstes deutsches Handwerk’ — The most beautiful German craftsmanship. The BACKPAGE Rose Gold 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 purchase options for the BACKPAGE Rose Gold will be published in the coming weeks.
