Too many casio purists here. But I'm happy to see this. There are not a lot of design choices available in fitness trackers. Apple watch works only with iOS. Samsung watch is too round & cute to suit wrists of a grown man, the build quality of Fossil is questionable. Garmin is too expensive. I'll wait for some reviews and then consider buying this.

I don't consider unlimited battery life (meaning battery will likely last longer than the watch itself), water resistance, and ruggedness to be part of "casio purism". I don't want to charge my watch daily or weekly, like I don't charge my clothes or shoes or umbrella.

Then......good news, you don't have to do this with this one! If you use it as a watch, and only use the fitness functions sporadically, then it will work forever just off solar power, like any solar powered casio for the last 20 years.
