Problems solved by technology

[0004] But the common shortcoming of the time zone time indicating mechanism of above-mentioned existing world time watch is: many of the 24 time zone place names marked on the ring-shaped edge of the dial are tilted or inverted, which is very inconvenient to observe, and every time you observe When changing the time in a certain time zone, you must first go through a process of aligning the place name of the main time zone with the time in the main time zone, which is very inconvenient to operate
And it is very inconvenient to produce, sell and use the two time zone universal time watch without the two time zone adjustment device

Description

technical field [0001] The invention relates to a world time watch, in particular to a two-time zone time indicating mechanism of the world time watch. Background technique [0002] Existing world time watches usually display the time around the world by means of a time zone ring with 24 time zone marks and a 24-hour pointer or a 24-hour dial. When in use, first turn the time zone ring, align the place name of the main time zone with the 24-hour pointer, and then find the place name of the time zone that needs to display the local time on the time zone ring, and the time indicated by the 24-hour scale on the dial where the place name of the time zone is aligned is the Time zone local time. [0003] The time zone time indicating mechanism of the existing world time watch also has other forms, for example, Chinese patent CN 2255055 Y just discloses a kind of " pointer type world time watch ", and its dial is marked with 24 time zone place names, and the dial is provided with ...
