In celebration of their thirteen years in November 2021, Moritz Grossmann Manufacture launched a new celebratory limited edition (of thirteen pieces, of course) version of the Backpage. You may recall our coverage of another thirteen year model, the Tremblage, last month.
The BACKPAGE collection was launched in 2018 with a simple concept – to put the back, front, courtesy of the ‘mirror-inverted’ Calibre 107.10.
For this new iteration, in deep blue, polished steel, and gold, in a 41mm (11.3mm thick) platinum case. The crown and pusher are both in platinum as well.
Beating at 18,800 VPH and with a power reserve of 42 hours, the manually-wound Calibre 107.0 is essentially a mirror image (hence the name) of the Calibre 100.1, but with some changes. For example, 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 that uses a mirrored escapement and the mirrored oscillation system – also including the balance spring coiling direction.
To display the winding wheels on the dial side, the dial train was reconfigured and arranged beneath a polished minute-wheel bridge. By moving the setting mechanism to the opposite side of the movement, the setting wheel extends all the way through the calibre.
When you pull the crown out, the mechanism switches from winding to setting. The brake position is sampled at the clutch lever and this motion is transferred to the brake spring via a push rod, which stops the balance. After adjusting the hands, the movement can be restarted by activating the pusher below the winding crown and the push rod returns to its rest position. This winder-pusher was developed by Moritz Grossmann to prevent dust from getting into the movement and the hands from being accidentally adjusted when the crown is pushed back.
On the rear side, the winding and hand-setting mechanism is integrated in the train bridge. The Grossmann balance, the hand-engraved (floral motif) balance cock and the snailing on the ratchet wheel are visible on the dial side.
This new variation of the BACKPAGE doesn’t have numerals or indices – it’s just all about blue for the 2/3 plate which is on the dial side. The colour is achieved courtesy of a thin layer of metal oxide which is applied after the components have been finished. In contrast, the gear wheels are gold-plated, there are gold chatons, and the polished hands are steel. Along with the hours and minutes, there is also a small (stop) seconds.
Coming on a blue hand-stitched alligator strap with a platinum buckle, the new limited edition BACKPAGE Blue has an RRP of AUD 85,500.
