Appearance: Sundials with compass.
Period: Early to late.
Power Source: None.
Construction: Apart from Inro-dokei and the later English pocket watch conversions, wadokei were not portable. The average Japanese in the Tokugawa period carried pocket sun dials in the form of inro with netsuke to hang from the belt of their kimono. The inro usually consisted of a compass and a sun dial and were quite accurate timekeepers, provided the sun was shining.
