Slate case with wide base and slightly protruding top plate.

The dial with Roman numerals, Breguet hands and an open Brocot escapement is located centrally between the thermometers. The central seconds hand is also worth mentioning.

At the bottom left we see the date display, consisting of the central hand for the months and the equatorial time, as well as three decentralized displays for day of the week, moon phase and date.
