Abstract
A watch has an hour wheel (17) which can be driven in rotation around an axis of rotation (10) by a drive, and has a rotatable universal-time hour wheel (13) arranged coaxially thereto. These two hour wheels are connected to each other by a spring-loaded detent connection. The universal-time hour wheel (13) is rotatably settable stepwise relative to the hour wheel (17) by a setting element. It overcomes the spring force of the detent connection, in which connection the setting element can be coupled to the universal-time hour wheel (13) for setting the latter and can be decoupled again after the setting. The hour wheel (17) is connected to an hour hand (2), and a universal-time hour hand (3) is connected to a universal-time hour wheel (13), by which means the times of two different time zones can be indicated on a stationary dial face. The setting element is a time-zone ring (8) which is arranged concentric to the axis of rotation (10), and can be rotatably set stepwise from detent position to detent position, and by which a transmission element for resetting the universal-time hour wheel (13) can be driven.
