Moritz Grossmann Backpage Tremblage Violet
The Moritz Grossmann Backpage Tremblage Violet forms part of a highly limited anniversary series created for the 200th birthday of Carl Moritz Grossmann, born on 27 March 1826. Grossmann’s influence reaches deeply into the identity of Glashütte watchmaking, not only through his work as a master watchmaker, but also through his scientific writing, educational vision, and role in founding the German Watchmaking School in Glashütte. This special platinum edition honours that heritage through a watch that places mechanical beauty at the centre of its design.
The BACKPAGE Tremblage Violet is not a conventional open-worked watch. Its construction is built around a mirrored movement architecture, allowing the most visually expressive components of the calibre to be viewed from the dial side. This gives the watch a remarkable sense of depth, as if the wearer is looking into the heart of a finished German movement without needing to turn the watch over.
Powering the watch is the Moritz Grossmann manufactory calibre 107.0, a manually wound movement regulated in five positions. While the calibre draws from the architectural language of the calibre 100.1, it has been fundamentally reinterpreted through mirrored construction. An additional wheel between the crown wheel and ratchet wheel reverses the drive train, while the escapement and oscillation system, including the balance spring coiling direction, are also mirrored to allow the mechanism to operate correctly.
The violet German silver dial element is finished using tremblage, one of the most demanding historical engraving techniques. The surface is created by hand, with the engraver moving the cutter in tiny trembling motions to achieve a richly textured, matte finish. In this violet edition, the colour brings an elegant and unexpected warmth to the watch, setting off the gold-plated gear wheels, raised gold chatons, polished screws, and untreated German silver with a distinctly refined character.
The dial composition balances mechanical openness with classical restraint. A full minute scale circles the display, while the hour numerals are arranged from 11 to 5 o’clock. The manually crafted steel hands are annealed to a brown-violet hue, giving the watch a subtle tonal relationship between the hands, dial, and violet kudu leather strap. This careful handling of colour gives the watch a quieter, more intimate presence than the Blue edition, while still retaining the same commanding mechanical theatre.
The platinum case measures 41 mm in diameter and 11.35 mm in height, giving the movement enough space to be admired without compromising wearability. The reverse of the watch carries the visible hand-setting train, while the balance cock includes a special “1826” engraving in reference to Moritz Grossmann’s birth year. Details such as the Grossmann balance, floral hand engraving, three-band snailing, and raised gold chatons reinforce the brand’s deep commitment to traditional finishing.
Limited to only twelve pieces, the Moritz Grossmann Backpage Tremblage Violet is a rare and deeply considered anniversary watch. It combines platinum, colour, mirrored movement construction, hand engraving, and historically informed German watchmaking into a timepiece designed for serious collectors of independent horology.
