The Chrono 4 130 Èdition Limitée consist of 130 pieces to celebrate the anniversary of the Maison, a Chrono 4 in a very refined version. The steel case has the same dimensions as the standard edition but it houses a skeleton dial, argenté or black, which reveals the main plate and the wheels with DLC® finishing, protected by an upper bridge in a special sapphire glass that is 3 tenths of a millimetre thick, an element of highly complex construction.
