During the late 16th and 17th centuries a special system of hour reckoning was employed in the Nuremberg area differing from that of the rest of Europe. It used equal hours, but numbered the daylight hours from 1 onwards and the night hours similarly. Very few clocks using this principle have survived, two important examples being a 14th-century iron wall clock, formerly in St. Sebaldus Church, Nuremberg, and a table clock of c. 1500, both now in the Germanisches Museum, Nuremberg. The dial of the latter has a set of concentric rings of hour figures and a single hour hand graduated according to the date of use.
