it's becoming more of a trend for companies to include GPS in their activity trackers polar to the reverse and actually included activity tracking in their latest GPS running watch I'm dan Graziano and I'm here with the polar m400 while you won't see any smart phone notifications on your wrist this watch can track your active time the steps you take distance you travel calories you burn and even your sleep at night the GPS and other sensors give an extra boost allowing me to track your distance pace time and altitude while running the watch is very smart it knows when it's being worn when you're sitting standing walking jogging or resting there's Bluetooth onboard so can connect with your mobile device or a heartrate monitor it's fully waterproof so you can shower with it or even go swimming and it charges with a normal USB cord rather than some specialized dock like most trackers on the market there's also a special feature on Polar's website that lets you relive your past runs in the form of a mini movie this includes details about your time and pace and even shows street view photos from your route it's a little gimmicky but I still think it's pretty cool the watch itself is a little big for a lot of work environments but this gives it great battery life with an active GPS signal you can expect to get about nine hours which should be more than enough time for most people to finish a marathon when used only as a watch and activity tracker that battery life jumps up to 24 days I got about 15 days of usage with a mix of light jogging about 20 and 30 minutes five days a week and daily activity tracking but your results will vary based on how often you use the GPS I did have trouble maintaining a GPS signal in New York City and that's something you should definitely consider before buying this watch without the GPS you can't get your pace or distance which makes the m400 simply an expensive stopwatch the polar and 400 is available now and starts at $200 in the US 134 pounds in the UK and 230 Australian dollars for more information be sure to check out my full review over at cnet.com I'm Dan Grazia prasena and that was a first look at the polar m400
