The time can be adjusted without stopping the watch.
The hour hand and the date move in tandem. By setting the hour hand, it is adjusted to indicate the date of your desired region having different time zone.
The time difference can be adjusted in one-hour increments.

UTC = Coordinated Universal Time
UTC is a universal standard time determined by international agreements. It is used as the official time around the world when recording the time. UTC is a time coordinated by adding leap seconds to the “International Atomic Time (UTI)” determined from atomic clocks in the world, in order to correct the deviation from the astronomically defined universal time (UT).
In the regions marked with 
, daylight saving time is introduced. (As of Oct, 2018)
There are time zone differences around the world based on time offsets from Coordinated Universal Time (UTC). The world is divided into 24 time zones where each part has a time difference of one hour. This system is adopted internationally in such a way that one full rotation of the earth corresponds to 24 hours (one day).
Depending on the country or the region, daylight saving time (summer time) is adopted individually.
Daylight saving time, being defined as time difference +1 hour, is a system that advances the time by 1 hour during summer time to prolong the daylight hours.
Time difference and daylight saving time are subject to change depending on the conditions of the respective countries or regions.
