The year 2026 is a special one for the Moritz Grossmann manufactory in Glashütte, as its founder and namesake was born on 27 March 1826 – exactly 200 years ago.
For the fourth special edition marking Moritz Grossmann’s 200th birthday, the manufactory will in May unveil two variants of the BACKPAGE Tremblage, in platinum with a dial finished in colourful violet or ‘blue meteor’ and with a tremblage engraving.
The watch highlights the aesthetic qualities of the manufactory’s movements, allowing almost all of the movement to be admired through an unusually large cut-out on the dial. On the reverse, there is a subtle reference to the anniversary on the balance cock in the form of an engraving reading ‘1826’, the year of Moritz Grossmann’s birth.
Both versions are limited to twelve watches each worldwide
BACKPAGE Tremblage
The watch highlights the aesthetic qualities of the manufactory’s movements, allowing almost all of the movement to be admired through an unusually large cut-out on the dial.
The dial
The remarkable concept of the BACKPAGE Tremblage is also celebrated on the dial side. A full minute scale and an hour arc from 11 to 5 o’clock serve as the framework for the moving calibre presentation. The recessed small seconds ring features an extravagant bearing for the seconds-hand arbor: a gold chaton as an insignia for the Backpage
With its exceptional colours, the dial serves as a stage for the brilliant choreography of the movement. The blue dial with blue annealed hands contrast vibrantly against the platinum case.
The BACKPAGE Tremblage in platinum features a dial finished in violet or Blue Meteor, enhanced with the Tremblage engraving technique.
The mirrored movement
In theory, the calibre 107.0 is a mirror image of the calibre 100.1. In practice, it has been newly designed. An additional wheel between the crown wheel and the ratchet wheel reverses the entire going train with the sense of rotation of the mainspring barrel. The wheel train runs in the right direction thanks to the mirrored escapement and the mirrored oscillation system — also including the balance spring coiling direction.
On the caseback side, the contiguous train bridge is decorated with Glashütte ribbing and endowed with hand-engraved calibre inscriptions. Interesting insights are provided by the cutouts above the oscillation system and parts of the balance stop spring as well as by the generous aperture above the manual winder with pusher ensemble. For the first time, this calibre configuration makes it possible to observe the win- ding and handsetting mechanism as well as the stop-balance device through the display back.
The highlights
The larger dimensions of the 2/3 plate necessitated design changes for the balance cock and the escape-wheel cock. The cantilevered geometry of the escape-wheel cock creates a balanced accent in the overall architecture of the movement. Additionally, the High-Artistic finish of the two components showcases attractive hand engravings, bevels, and chamfers. Further captivating details include the polished minute-wheelbridge and the lavishly finished dial train with its spoked and chamfered wheels.
