First of all in order to change the time settings on your Garmin vivomove hold the touchscreen in order to view the menu then from the options that appear select “set time” then select “manual” then select or set the date and time as per your requirements then select the time or date in order to move to the next screen and then further follow the instructions as they appear on the screen. I hope this gets your time settings done easily on Garmin vivomove and if you know more about them you must visit them Garmin Helpline Number Uk & http://www.garmincustomerservice.co.uk/
