A 'simple to use' dual time zone watch which does not use geolocation (saving battery). Instead simply use the top and bottom buttons to set the top time. The bottom time is always set to the current phone time. The middle button flips the home and globe icon to match the bottom time to your location (home or away). If you are home and your contact is away set the bottom icon to home and adjust the top time to their time zone. If you are away, flip the icon to the globe and set the top time to your normal home time zone.
