Watch with time zone display

Abstract

The analogue display watch includes two separate time displays (40, 44) for first and second time zones, and a time zone indicator (50), which includes a place ring (53) associated with two apertures (51, 52) shifted angularly by 1/24th of a revolution, and one of which is used in combination with winter time and the other with daylight saving time (DST). A first, manual, time-setting device (31) can simultaneously set the time of the first and second time displays (40, 44). A second, manual, time-setting device can rotate the second time display (44) and the time zone indicator (50) together, step-by-step, without changing the state of the first time display (40). A manual corrector (34, 63) rotates the place ring (53) step-by-step without changing the state of the first and second time displays (40, 44). The place symbols (54) are distributed over the circumference of the place ring (53) with a step of 1/96th of a revolution, so as to include symbols (54a, 54b) representing time zones that differ from UTC by a non-integer number of hours. With these features, simple manipulations can display the time in any place in the world and time zone changes can be performed easily while taking account of daylight saving time and a change in hemisphere, where necessary.
