Fitbit is preparing to launch three new fitness trackers in the coming weeks. Two of those will be the Charge and Charge HR. The Charge looks to be a revision of the Fitbit Force, which was pulled off the market after it caused bad skin reactions for some customers. Charge HR will offer a bit extra with the addition of PurePulse, the company's wrist-based heart rate monitoring system. But there's more: Fitbit has also been working on a third, flagship wearable for serious athletes. It's the Fitbit Surge.

Apparently Fitbit thinks Surge is several steps beyond your average "wearable." The company refers to it as a "superwatch" according to marketing materials The Verge has received from a tipster. Set to be priced at $249, the Surge includes built-in GPS tracking — a big draw for runners — PurePulse heart rate monitoring, and promises to provide real time workout data for a variety of activities. You'll get stats on distance, pace, elevation climbed, heart rate intensity, and so on.

Plus all the activity and sleep tracking you'd expect

And since the company hopes you'll be wearing it constantly, the Surge will also carry over Fitbit's 24/7 activity tracking to make sure you're moving enough throughout the day. Some of those metrics include calories burned, floors climbed, and active minutes. There's sleep tracking too, which will monitor the quality of your night's rest and wake you up each morning with a vibrating alarm.

Like competing fitness trackers, you'll be able to wirelessly sync all that data to Fitbit's app, where you can also log meal intake and earn badges for your progress in meeting health goals. Surge will offer your basic "smart" notifications for phone calls and texts, and you can also control music playback with the watch. But don't call it a smartwatch; no one's going to be buying this as a replacement for Android Wear or the Apple Watch. When Surge eventually launches, it'll come in three colors: black, slate, and a more colorful tangerine option. Want the full details? Here's everything the marketing sheet tells us.
