Moritz Grossmann · POWER RESERVE / calibre 100.2
The movement in detail
The POWER RESERVE turns its remaining energy into a small two-colour bar. A planetary gear system drives that quiet display. A short line replaces an additional hand on the dial, an appealing solution for someone drawn to restrained classical design.
The in-house calibre 100.2 is hand-wound. It contains 227 components, 26 jewels and a 14.2 mm balance operating at 18,000 vibrations per hour. A button beside the crown disengages time-setting mode and restarts the movement. For the owner, it makes finishing the setting process a distinct, deliberate action.
A sapphire back reveals the untreated German-silver two-thirds plate, engraving and gold chatons. The construction deserves attention alongside the finishing. The main photograph shows a rose-gold execution from the official archive; the current range also includes other versions.
The POWER RESERVE measures 41 × 11.65 mm and provides 42 hours of reserve. After a weekend without winding, it may need resetting. Its attraction lies in the character of its hand-wound mechanism and display architecture; someone prioritising autonomy may prefer another model.
