Unlike conventional shaped watches that conceal a round calibre inside an architectural case, Gerald Charles designed the GCA11000 to follow the Masterlink’s asymmetrical geometry.
The movement is not adapted to the case, but it is shaped by it. The case defines volumes, axes, and proportions of the watch, making it truly unique.
The movement delivers over 100 years of precision for the day, month, leap year and moon phases without adjustment.
This entirely in-house perpetual calendar caliber is Gerald Charles’ most complex movement to date, demanding absolute control over every component.
