’It is only with the heart that one can see rightly; what is essential is invisible to the eye.’ Reversing this quote from the celebrated classic ‘The Little Prince’ by Saint-Exupéry, the Moritz Grossmann Manufacture has mirrored the mechanism of Calibre 107.0 on the dial side of the BACKPAGE Transparent, transforming it into a visual experience for the eye. The mechanical heart of the BACKPAGE Transparent was shifted from the back of the movement to the front so that its delicate beauty can be admired on the wrist.

With the BACKPAGE Transparent, Moritz Grossmann offers a showcase for the beauty of Grossmann’s watchmaking artistry. The watchmakers from Grossmann have designed the calibre 107.0 with a mirrored High-Artistic Finish and moved it to the dial side. The moving spectacle of the movement with Grossmann’s balance wheel, ratchet wheel, crown wheel and Glashütte stopwork with backlash can be admired in its entirety through the transparent sapphire crystal dial.

Calibre 107.0

Calibre 107.0 is essentially a mirror image of the calibre 100.1, but with crucial new design elements. 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.

Both the design and construction of the balance cock and escape-wheel cock were adapted to the larger dimensions of the 3/4 plate. The escapement wheel and the cantilevered balance cock with its hand-engraved, floral pattern create a balanced accent in the overall arrangement of the movement. The High-Artistic finish showcases attractive hand engravings, bevels, and chamfers.

Transparent sapphire crystal dial

Black Moritz Grossmann lettering adorns the transparent sapphire crystal dial. The full minute scale and an hour display from 11 to 5 o’clock and the subsidiary seconds are also in black and form a beautiful contrast to the rose gold and white gold colours of the case.

Handcrafted hands and screws annealed to a brown-violet hue in the manufactory complete the elegant spectrum of colours.

Dial train and minute wheel bridge

To display the winding wheels on the dial side, the dial train was reconfigured and exquisitely finished. The artistically crafted train wheels were arranged beneath a lavishly polished minute-wheel bridge.

By moving the hand setting mechanism to the opposite side of the movement, the setting wheel extends all the way through the calibre. The new arrangement created space for the optimised barrel bearing and the ratchet wheel, which was also shifted to the front side.

The winder with pusher and stop seconds

On the new rear side of the movement, the winding and hand-setting mechanism is now openly integrated in the train bridge, so its functionality can be fully observed for the first time. Almost all parts are mirrored in order to guarantee their function even when mounted in the opposite position while ensuring the position of the lever remains unchanged.

After a short pull on the winding crown, the mechanism switches from winding mechanism to hand setting. At the same time, 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 comfortably restarted by activating the pusher below the winding crown and the push rod returns to its rest position.

This technical highlight is a mechanism developed by Moritz Grossmann that prevents dust from getting into the movement and prevents the hands from being accidentally adjusted when the crown is pushed back.
