The outsize date mechanism
A large display in a compact space: The date is indicated in a gold frame with numerals that are about three times larger than those in watches of comparable dimensions. It consists of two separate display elements: the units disc and the tens cross. They revolve one above the other with a clearance of only 0.15 millimetres, which requires extreme dexterity during assembly.
