Moritz Grossmann makes its first inhouse automatic movement of the modern era


German watchmaker Moritz Grossmann ended a global roadshow in London today and used its event to unveil a first self-winding inhouse movement.

The way its new calibre 106.0 winds its mainspring is more like the pocket watches of the 19th century that Moritz Grossmann used to produce in Glashütte.

Instead of an oscillating weight, the movement has a sprung hammer that swings in both directions in a similar way to a pendulum, turning a ratchet that winds the spring.


The company’s CEO Christine Hutter says it takes about 6 hours of wearing the watch to fully wind it, and 72 hours for the stored power to unwind.

The eye-catching movement is visible through a large sapphire on the back of the watch’s 41mm case.

It is sold in either white or rose gold, with deliveries to retail partners (New York’s Cellini and Denver’s Oster Jewelers) this month.

The dial also borrows from the design of old Moritz Grossmann pocket watches, with Roman numerals and pear-shape tipped handmade hands.

The hour and minute hands measure just 0.1 mm in width at the narrowest point.
