GPS + Full-Color Map

The current location is determined by energy-efficient GPS and indicated  on a full-color offline map.

Built in low-power GPS

Supports positioning data from three satellites (American GPS, Russian GLONASS and Japanese “MICHIBIKI” QZSS). 
Steadily receives positioning data and displays your current position on a full-color map.

Full-color map display

The current location is determined based on positioning information received from GPS satellites 
and displayed on a high-resolution full-color map.

Offline map usage capability

Map data downloading is handled through a tie-up with MapBox, a supplier of map data for countries worldwide. 
The map data can be displayed even when the user’s smartphone is offline or out of range of mobile device radio wave transmissions.

Original watch face linked  with GPS function


Journey shows a map of the current location in the background of the analog-style watch display. When the user saves events with locations to Google Calendar, the watch displays up to three upcoming events and maps of the scheduled destinations. Users can save destinations beforehand from an itinerary, such as outdoor destinations or sightseeing spots, so that they always have a view of the next destination to look forward to and a map to guide them.


The Place watch face is based on a map display, and can show a map that includes the location of events scheduled in Google Calendar, as well as your current position, on the watch face. Furthermore, the smaller dials support the complication functionality of Wear OS by Google, allowing you to customize the information that appears on the watch face, such as altitude, atmospheric pressure, and remaining battery charge, as well as data from apps by Google or third parties.


An advanced watch face is realized through a design representing the GPS and map functions and animation of the map display.


Traveler enables the user to switch the type of information displayed in the window in the lower part of the watch face, and to launch the corresponding app just by tapping the watch face of the device.
