The three movements of our Hamburg client were finished using three different decoration methods, whereby each movement received a special element put in the spotlight: the high art of diamond setting; a handguilloche dial with characteristic Breguet frosted finish; and a skeletonized dial to perfectly harmonize with the skeletonized Hebdomas movement. The balance, which oscillates 3,456,000 times in an eight-day period, is visible from the front of these movements. The unusually thick case was specially created to house the 180-centimeter-long mainspring. This is a special commission that doesn’t exist in any other form.
