Compact rectangular form: Easy to read, easy to wear – This watch features an oblong, angular shape designed not to interfere with the back of the hand and a digital LCD with a three-tiered display layout – all in a lightweight, compact profile suited to everyday use. The band length is adjustable from 145 to 200 mm to comfortably fit even slimmer wrists. The design ensures a nice, snug fit for anyone to wear and enjoy.

New shock-resistant structure for more exterior design possibilities – The watch features a shock-resistant construction combining the bezel, case, and band connectors. Unlike conventional structures, in which the case is covered by the bezel and the band is connected directly, this approach employs each of these parts as structural components while incorporating their shapes and colors into the look of the design, as well. Glass fiber-reinforced resin is used for the case.

Everyday functionality tailored to lifestyle needs – A step tracker is included, adding handy functionality for daily life with an accelerometer to count steps. The watch also displays progress you’ve made toward your goal on a graph to support your active lifestyle. In addition, smartphone pairing via Bluetooth® delivers automatic time correction and makes it easy to configure various functions from the app.

Super Illuminator – High-brightness auto LED backlight for maintaining watch readability in the dark.
