Appearance: Lantern clock on four legged stand. Originally with covered hood – however most hoods are missing.
Period: Early and Middle, although produced through to the late period.
Escapement: Single and double foliot, however some very late examples had balance springs.
Power Source: Lead weight
Construction: Lantern clocks generally had square or rectangular pillars. Early clocks were wholly of iron. Middle period examples had brass side plates and some components. Later examples used brass extensively.
Dai-dokei have the clock movement placed on open four legged stands so that they were at eye level for people seated on the tatami floor mats. They were located in the tokonoma (alcove) of the Japanese living room. Stands were ornate and decorative. Large versions of the Dai-dokei were also made for use mainly in public places such as castles, corridors and entrance halls.
Example: Dai-dokei in author’s Collection.
