WATCH MODE
WATCH MAIN TIME
Selection of Main Time is a Set T (Time) menu item.
Time of Day and Date can be set when either Home or Away time is selected as the Watch Main.
Home Time is the current time at your home location and is normally selected as the Watch Main Time.
Away Time, set by Hour Differential, is the current Time at a remote travel location. Upon arrival at the location, Away
Time can be interchanged with Home Time to make it the Watch Main Time while visiting the travel location.
Dual Time is the second time (Away or Home) that can be displayed simultaneously with Watch Main Time with set On. It
is a +/- Hour Differential based on the Watch Main Time that is selected (Home or Away).
Once a differential is set, it will automatically change when Time of Day is changed. Also, when Away Time is selected to
be the Watch Main Time (while at a travel location), it can be changed by changing the differential instead of the Time of
Day.
