The time indicated by the hour hand and minute hand (Dual Time) can be set to the
time you want without stopping watch operation.
You can set the 12-hour and 24-hour hands to your basic time (the current time in the
time zone where you normally use the watch), and change the hour hand to any
other time (Dual Time) you want (current time in a city you are visiting, etc.).
When setting the time, make sure that the date setting is correct. If it isn’t, correct the
date setting.
