Design & Technology
Advanced technology and design supporting superior performance.

Measure the intensity of your exercise in real time.
Optical sensor (heart rate measurement)
Measure your heart rate simply by strapping the watch on your wrist.
Display data such as your current beats per minute and heart rate zone in numerical values and as graphs and graphics.
You can use this information to help you improve your exercise capabilities, increase your endurance, and engage in heart rate training.

Optical sensor
An optical sensor is mounted on the case back of the watch. This sensor measures your estimated heart rate by shining an LED light to detect the flow of blood in your body.

* This device displays an estimated heart rate based on the pulse measured by the sensor mounted on the back side (rear cover).
The heart rate values displayed by the watch are approximate, and no guarantees are made concerning their accuracy.
* The heart rate measurement functionality of this watch is intended for use during recreational activities, and cannot be used for any kind of medical treatment.

Get the information you want to know right away.
Large color LCD ＋ monochrome LCD [ dual layer display ]
The watch uses an easy-to-read, 1.32 inch display that is large and easy to operate with touch operation.
Switch between the color LCD and monochrome LCD as the situation requires to achieve low power consumption and readability.
You can also configure up to four different measurement screens.*
Switch between different screens depending on what you want to do,
to allow instant confirmation of the data you're looking for while you're exercising.

* ACTIVITY: When using running or trail running

Monochrome LCD
The display of both the time and the various measurements consumes only a small amount of power.
The display is easy to read even outdoors, such as directly under the sun.

Color LCD
Display detailed information such as maps, sensor readings, and various notifications in a colorful, high-definition display.

Even more comfortable to wear.
Soft urethane band
The watch uses a soft urethane material that makes it both flexible and durable. The double-pin buckle prevents slippage, while the larger number of holes in the band allows you to adjust it for an even finer fit. Breathability is also improved, reducing the feeling of the watch sticking to the skin due to sweat or other factors.

Lighter, and sportier.
Bezel design
Resin is used in the bezel to achieve a weight of approx. 81g (2.9 oz), the lightest in the series. Through unique molding technologies, the bezel is given a three-dimensional treatment in all aspects, including contours and grooves, and has been finished with a material that possesses a brilliant, metal-like sheen. The bezel is strong enough to protect the display, but also has a functional beauty worthy of outdoor gear.

Features
Know your condition Know your location

Heart Rate Measurement Functionality
Use this data for your training, whether it be managing the pace of your activity or increasing your endurance.

Detect your motion to take measurements automatically.
Dedicated heart rate watch face
The watch face used in these models links up with the heart rate measurement functionality.
When the internal accelerometer detects motion (walking, running, or cycling), measurement begins automatically.

Use as an index for pace management.
Heart rate measurement + heart rate zone display
SUPPORTED ACTIVITIES Running, Trail running, Trekking, Cycling, Paddling, Snow activities.

Heart rate zone alerts
If you set a particular heart rate zone in advance, you will be notified via a display and a vibration when you have exceeded that zone.
This helps to prevent you from overexerting yourself.

Support for increased endurance.
Measure your VO2 max
Measure your maximum oxygen consumption for your body per minute (for each kilogram of body weight).
You can use this as a guide for endurance activities, such as running.

* Note that your resting heart rate and maximum heart rate must be set up before your VO2 max can be measured.

GPS + Color Map Display
For both new places and old favorites. View a map while you enjoy your activities.

Instantly find out where you are now.
Current location display
Display your current position and your recorded movement log on a high-definition color map while you measure your activity. This allows you to check your current position without having to get out your smartphone. Use this feature in situations such as when you want to challenge yourself with new courses or when you want to run while traveling.

Easily set up routes.
Route input
Import GPS log data (such as for past routes or recommended routes from ViewRanger) into the watch by using Google Drive™, and set these routes for running. Check your route on the map while you run as a form of simple navigation.

Share your favorite routes.
Creation of original routes
Save the routes on which you travel during your activities as activity data. You can use markers to record checkpoints for locations such as places where water is available, and create your own running routes. You can then share these routes with others.
