When Moritz Grossmann wanted to flip its movement over to show the underside on the dial side, there was one problem.
You could mount the hands on the back of a movement, but they would turn in the wrong direction.
That challenge was solved in 2018 when the Glasshutte-based watchmaker unveiled its first BACKPAGE housing the calibre 107.0.
That movement is almost identical to the manufacturer’s 100.1, except for an additional wheel between the crown wheel and the ratchet wheel that 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 and main spring system.
That first BACKPAGE was made in a limited run of 18 platinum watches, and there have since been additions to the collection in rose gold and with different dial designs such as the BACKPAGE Transparent launched last year, but all created around the upside down calibre 107.0.
This month Moritz Grossmann has extended the line again with a 41mm platinum model with a blue metal oxide finish on the movement, gold-plated gear wheels, gold chatons and polished steel hands.
The watch is for sale at the Moritz Grossmann online boutique for €41,000.
