STEP TRACKER. A built-in 3-axis acceleration sensor begins counting steps the moment you start to walk.

and a status indicator window in the upper right area of the dial displays the target achievement rate.
This data can help motivate you to increase your step count.
[App] Step Count Measurement Data Transfer. Measurement data can be transferred for use to a dedicated app. In addition to manual transfers, the app conducts automatic transfers four times a day.

When activated by the smartphone, the step count is displayed graphically on a map every 30 minutes.
TIMER. A multi-timer function useful for interval workouts can be set for up to five different times.

Auto Repeat (maximum 20 times) and Auto Start are available along with an announcement notice function.
[App] Create Timer Menu. Up to 20 sets of 5 timers can be set up on the dedicated app. This makes it easy to create a menu of workouts and intervals as sets of workouts and break times that repeat within a certain period. You can save the menus you create under individual titles. You can then call them up instantly according to the day of the workout and transmit the settings to the watch.
