A watch, with an 8 month coin cell battery, that tracks steps and sleep; and connects via bluetooth. It's extremely well made, simple, beautiful, and has a great ecosystem with brilliant software, which is particularly good when used in conjunction with the Withings ecosystem. Lots of watch straps available for it too.
If you want a smart watch that doesn't make distract, and doesn't need constant charging and attention, these are lovely!
Was searching for a replacement for one I gave to a friend, and was shocked to find this price.
No heart rate or text / phone call is a real bummer. Traditional watches are going the way of the dodo.
