Calibre Family 94000
The hand-wound 94800-calibre movement features two barrels, which provide the energy for the higher torque required to drive the constant-force tourbillon. In the 94900 version, it also provides the enormous amount of power needed for the astronomical module in the Portugieser Sidérale Scafusia. This extravagant timepiece features displays for sidereal and solar time, the times of sunrise and sunset, and a perpetual calendar, as well as showing the section of the sky currently visible in the real sky. The 94800 calibre also drives the tourbillon, the moon phase display and the power reserve display.
