And thirdly, the Pebble Round 2 is one of the thinnest smartwatches on the market. The watch is only 8.1 millimeters thick. Since Pebble forgoes a heart rate sensor, the back is flat rather than curved, so unlike most smartwatches, there is no need to account for a bump that manufacturers often omit from the dimensions. As a comparison with the 11.6-millimeter-thick Garmin Forerunner 165 ($196 on Amazon) shows, those few millimeters make a noticeable difference on the wrist.
According to Nick Lum, the Pebble Round 2 averages just under ten days of battery life – the advertised 14 days are only possible if some features, such as the touchscreen, are disabled. The reviewer mainly criticizes the fact that one of the four buttons does not always respond correctly to inputs, a replacement smartwatch also suffers from the same problem. More detailed reviews are likely to be published by the time shipping begins in the coming weeks.
