The BACKPAGE – a spectacular showcase of Grossmann’s watchmaking prowess – was presented by Moritz Grossmann in March 2018. A timepiece that raised a question not only shared by enthusiasts and admirers of mechanical watchmaking – which is more beautiful: the view of the front or the back.

The platinum statement piece, limited to 18 pieces, ushered in a completely new design in the world of haute horlogerie by making the signature mechanical highlights of the manufacture calibre – such as the Grossmann balance, the balance cock hand-engraved with floral motifs, and the 3-band snailing on the ratchet wheel – visible on the dial.

Legendary in connoisseur circles, these movement components enthral aficionados with an exceptionally large dial cut-out. The small seconds display also enjoys a prominent position thanks to the extravagant bearing for the second hand featuring a gold chaton.

The BACKPAGE Transparent launched last year, in which the precision-mechanical ensemble was accented by a sapphire crystal printed with indices and numerals, also delighted devotees of Glashütte fine watchmaking.

This year, Moritz Grossmann proudly presents a new variation of the BACKPAGE principle that dispenses entirely with numerals and indices and adds an expressive colour, the BACKPAGE Blue. Thanks to a wafer-thin layer of metal oxide, which is applied with nanometric precision of 1 millionth of a millimetre after finishing the components, all frame parts are resplendent in a deep blue hue.

The colour is durable and resistant to environmental influences, possessing a unique brilliance that creates a charming contrast to the gold-plated gear wheels, the gold chatons, the polished steel hands crafted in the manufactory, the carefully bevelled and polished screw heads and the ratchet wheel embellished with a 3-band snailing finish.

An innovative coating process is employed on the surfaces of all the frame parts, resulting in a fascinating interplay of light and colour that enhances the beauty of the mechanism, displayed and finished with consummate virtuosity, directly on the wrist.
The manufactory calibre 107.0: a new take on traditional Glashütte watchmaking artistry
The calibre 107.0 was designed by Moritz Grossmann to attain this expressive visual impression on the front of the dial. While at first glance it may seem to be a mirror image of the calibre 100.1, it is actually based on a new technical approach.

An additional wheel between the crown wheel and the ratchet wheel reverses the entire drive train with respect to the 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.

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 arrangement of the movement. The exceptionally luxurious high-artistic finish of the two components is fascinating with its masterly handcrafted engravings, chamfers and bevels.
The minute-wheel bridge: an innovative mechanism
To achieve the desired presence of the winding wheels on the dial side, the dial train was reconfigured. The artistically finished train wheels were arranged beneath a highly polished and bevelled minute-wheel bridge.

The new arrangement created space for the optimised barrel bearing and the ratchet wheel, which was also shifted to the front side.
The back of the movement: clear the stage for the winder with pusher and stop seconds
Even though the front mesmerises with a deft display of carefully selected components, the view of the back is equally captivating.

One of the highlights here is the functional sequence of the winding mechanism, which is openly integrated into the wheel bridge. Almost all of its components are mirrored in order to guarantee their function even when mounted in the opposite position while ensuring the position of the lever remains unchanged.

The stop-seconds and stop-balance functions have also been redesigned. In the hand-setting mechanism, the brake position is sampled at the clutch lever and, via a push rod, transferred to the brake spring, which then stops the balance. After the pusher is activated and the movement starts, the brake spring returns the push rod to its rest position.
Platinum case
A platinum case provides a fitting accompaniment for the anniversary model, which is worn with a dark blue strap made of hand-stitched alligator leather.
