The art of watchmaking from Glashütte: the calibre 100.2
The calibre 100.2 is an extension of the calibre 100.1. Thanks to the differential gear, it houses an additional mechanism for displaying the power reserve.
A sapphire crystal back on the reverse of the watch reveals the intricately finished parts in the POWER RESERVE, showcasing the ‘Schönstes deutsches Handwerk’ in the form of the finest cuts and polishes from the Moritz Grossmann manufactory. The calibre 100.2 of the POWER RESERVE also features a cantilevered balance cock with Grossmann micrometre screw and the mass optimised Grossmann balance along with a separately removable winding block.
The Grossmann manual winder with pusher
Grossmann manual winder with pusher contains a perfected hand setting mechanism, which eliminates two potential problem areas: avoiding the ingress of foreign particles during the adjustment process and altering the hands unintentionally when pushing the crown back into place. After a short pull on the winding crown, the mechanism switches to hand setting and simultaneously stops the movement.
The crown immediately returns to its original position, allowing the hands to be adjusted precisely. The movement is then restarted using the pusher below the winding crown without having to move the crown again. At the same time, the mechanism is reset to winding mode.
