Watch with time zone display

Abstract

The invention relates to an analog display watch that comprises two separate time displays (40, 44) for a first and second time zone, and a time zone indicator (50) comprising a place ring (53) associated with two counters (51, 52) that are angularly offset by 1 / 24 of a turn, one of which is used in combination with Standard Time and the other with Daylight Savings Time (DST). A primary manual time set device (31) enables the first and second time displays (40, 44) to be set separately. A second manual time set device allows the entire device to turn the second time display (44) and the time zone indicator (50) together step by step without modifying the status of the first time display (40). A manual corrector (34, 63) enables the place ring (53) to turn step by step without modifying the status of the first and second time displays (40 and 44). Place symbols (54) are distributed on the circumference of the place ring (53) with a step of a 1 / 96 turn, such that the place symbols (54) include symbols (54a, 54b) that represent time zones that differ by a number of hours that is not a whole number relative to Coordinated Universal Time (UTC). With these characteristics, simple manipulations will enable the time at any place in the world to be displayed, and changes to time zones to be made easily, taking into account Daylight Savings Time and a change of hemisphere, if applicable.

Description

technical field [0001] The invention relates to a watch with an analog display, comprising: a first time display device for a first time zone, associated with a first time setting device; a second time display device for a second time zone, associated with a first time setting device two manual time setting devices are associated; and a time zone indicator comprising at least one index and a location ring with a location symbol, wherein the location symbol represents a time zone, and the location ring can be rotated against said index, or Conversely, the first manual time setting device can simultaneously set the time of the first and second time display devices, the second time setting device can make the second time display device and the time zone indicator rotate step by step together, and The state of the first time display device is not changed. Background technique [0002] Such a watch is described in patent US 3633354 (=DE 1933049). in the patent figure 1 with 2...

AI Technical Summary

Problems solved by technology

In patent US 4717260 a basic system has been provided which allows a half hour time difference on a watch with world time, but which cannot be used with a dial with two time indications

[0006] Due to the above problems, most current use of wristwatches showing time in two time zones is only convenient in certain standard situations, while becoming overly complicated in other situations
