FAQS
If you can’t find answers to your questions here, please feel free to contact a member of our service staff.
Calibre Family 52000
The twin barrels are the trademark feature of the 52000-calibre family. They supply the watches with sufficient energy for a 7-day power reserve and drive energy-sapping complications like the annual calendar and perpetual calendar.
Double Moon
The moon phase and its mirror image show the state of the moon in both the northern and southern hemispheres.
Perpetual calendar
The perpetual calendar is one of the most fascinating haute horlogerie complications: It is mechanically programmed for 577 years.
