Historical significance
- A blued steel hand, shaped like an arrow, indicates the hours painted on the white enamel dial.
- The brass movement, which is not gilded, signed Jacob Brandt, is fitted with four Egyptian pillars. It is unusual, as it has no fusee: instead, a going barrel meshes directly with the first wheel of the gear train. A steel lever with two pins, which alter the length of the balance spring, replaces the regulating rosette. The free end of the lever moves along a scale from 1 to 5, with the numbers engraved in Arabic numerals on the plate.
