Moritz Grossmann Backpage Green Platinum
Reference: MG-003495
A splash of colour and a fascinating design to celebrate Moritz Grossmann’s 15th anniversary: BACKPAGE Green
The BACKPAGE model accentuates the aesthetics of the intriguing mechanical watch movement. Thanks to the large dial cutouts, the most beautiful details of the manufactory’s skill in watchmaking are rendered visible. Reading the time also gives a view of partial sections of the highly finished calibre 107.0: from the dial side, its defining stylistic elements are revealed, such as the Grossmann balance, the balance cock that has been hand-engraved with floral motifs and the three-band snailing on the ratchet wheel. Normally these components would be found on the back of a watch. However, the mirrored construction of the movement gives it a whole new look. Thanks to the extravagant mounting of the seconds hand shaft in a gold chaton, the small seconds display is also located in a prominent position. The winder with pusher and stop seconds, which was developed in-house, can be seen on the back of the watch.
This limited edition BACKPAGE can be identified by the green colour on the remaining elements of the dial, which is key to the effect of the watch thanks to its rich, warm nuances. The green gives rise to an exciting contrast to the gold-plated gear wheels, the gold chatons and the carefully bevelled and polished screw heads, all of which are further aesthetic characteristics of the high-quality finish found on Grossmann movements. The sophisticated interplay of light and colour serves to highlight the masterfully finished mechanism directly on the wrist. The handcrafted hands circle above it, annealed to an attractive and subtle brown-violet hue. The manufactory calibre 107.0, representing a reimagining of the traditional Glashütte art of watchmaking, was designed with the aim of showcasing the expressive look on the front of the dial. Although it appears to be a mirror image of the calibre 100.1, it required a completely new technical approach. Only in this way could the time be displayed on the flip side of the movement to create a thrilling juxtaposition of time. To achieve this, an additional gear wheel had to be integrated between the crown wheel and the ratchet wheel that also reverses the entire drive train with respect to the rotation of the mainspring barrel. The escapement and oscillator was also mirrored, including the winding direction of the spiral spring. This required the balance and escape wheel cock to be adjusted. The particularly high-quality High Artistic Finish of both components fascinates with the masterful hand engraving, chamfering and bevelling.
The perfect frame: an exquisite platinum case, limited to 25 pieces worldwide, encases this special model that marks the 15th anniversary of the manufactory. The appliqués on the dial also match the sophistication of the case to balance the overall aesthetic which is finished off with an elegant black, genuine strap and platinum pin buckle.
