I recently replaced both my Pebble Time Steel watch (just bought out by Fitbit) and my Fitbit Charge HR with a single Fitbit Blaze. The Blaze is a fitness device with some notification features and some nice watch faces. Battery life is around 5 days. Overall I'm quite liking it although it does not have all the fancier features of the Pebble watch.
What I do like over the Fitbit Charge HR, is that you can swap out wristbands and frames.
