Moritz Grossmann BACKPAGE Collection
The BACKPAGE embodies pure horological artistry, turning the movement itself into the star of the design. Traditionally admired only through the display back, details such as the Grossmann balance, hand-engraved balance cock, and ratchet wheel with three-band snailing now take center stage on the dial side—thanks to the inventive calibre 107.0.
This mirror-inverted movement transforms the watch into a living showcase of fine German watchmaking, revealed through a large dial aperture that doubles as a stage for mechanical beauty.
Launched to celebrate the brand’s 13th anniversary, the BACKPAGE Anniversary Edition is a masterpiece of contrast and depth, uniting deep blue, polished steel, and gold elements within a platinum case. Limited to just 13 pieces worldwide, it captures Grossmann’s legacy of precision and innovation.
For its 15th anniversary, the manufactory unveiled the BACKPAGE Green, a striking limited edition defined by warm green accents across the dial. This rich hue plays against gold-plated gear wheels, gold chatons, and meticulously polished screw heads—hallmarks of Grossmann’s exceptional finishing.
Available in platinum or rose gold, the BACKPAGE collection offers collectors an extraordinary view into the heart of fine watchmaking, where engineering brilliance meets timeless elegance.
