Introducing a new model in the step tracker series to support people who are active every day
The acceleration sensor detects movement and automatically counts steps as soon as you start walking.
Displays the total number of steps taken per day and the goal achievement rate
You can also transfer the measurement data to a dedicated app and manage it as a life log.
The colors are natural and perfect for daily use, adding a comfortable touch to your everyday life, and making an accent to an effortless casual style.
The simple octagonal shape is combined with a color block design and light accent colors, and the fabric pattern goes well with sportswear, giving it a sporty impression.
The glass is printed with a metallic finish to enhance the texture.
The base color of the watch is a matte black or dull color, making it easy to use on a daily basis.
Compact size and slim design for a better fit
The length of the band has also been revised for better fit.
Comfortable to wear even for people with thin arms
Biomass plastic is used for the main resin parts such as the bezel and band.
The material is made from renewable organic resources, which is expected to contribute to reducing the environmental impact.
Casual, active and ethical
We support people who enjoy every day in their own way.
