$35.82 USD · In stock · Lowest price in 30 days
Sold by MaGGzin
A tracker that handles the desk-to-gym day without a second device. Bluetooth 4.0 pairs it with iOS 8.0 or Android 4.4 and above, so calls, messages and app notifications surface on the colour display — and you can trigger your phone's camera remotely from your wrist. Smart reminders nudge you when you've been seated too long, while step count, distance and heart rate build a picture of a working day. The soft two-tone silicone strap and glossy black body read as understated rather than sporty, in black-grey, black-red or black-green.
