本发明涉及一种具有可手动操作的外环（33）的通用时钟（10），以选择24中的一个时区，所述显示装置再现所选择的时间段的时间。 为了这个目的，提供了用于检测所述外圈的旋转位置（33）的装置，其是在外圈的永久磁铁（39A-J）（33）和磁性开关（27A-H）（11，12）的在所述钟表壳体的特定布置在一个 提供一定数目以及在运动（21）的电子评估单元。 永久磁铁（39A-J），以确定在磁性开关（图27a-h）中，它们共同的二进制状态，作为一个信号，分别。 被解释为状态模式。 磁性开关（图27a-h）和永久磁铁（39A-j）的特定布置使得其自己的，从其他状态模式，它允许一个明确的结论为每个旋转位置的外环（33）的选定的旋转位置的每个不同。

The invention relates to a Universal timepiece (10) with a manually actuatable outer ring (33) to select one of twenty-four time zones, said display means reproduces the time of the selected time zone. For this purpose, a means for detecting the rotational position of the outer ring (33) is provided which is a particular arrangement of permanent magnets (39a-j) in the outer ring (33) and magnetic switches (27a-h) in the watch case (11, 12) in a certain number and an electronic evaluation system in the movement (21) provides. The permanent magnets (39a-j) to determine the binary states of the magnetic switches (27a-h), which together, as a signal, respectively. be regarded as the state patterns. The particular arrangement of the magnetic switches (27a-h) and the permanent magnets (39a-j) causes for each rotational position its own, from the others each different state pattern, which allows a clear conclusion on the selected rotational position of the outer ring (33).
