I'd really like to see autonomous watches with GPS, providing minimal smartphone functionality (navigation, calls and messages), plus serious fitness tracking.

But at the same time I'm hesitant to wear one of those devices without reasonable guarantees big brother is not collecting data. Therefore, something like AsteroidOS seems ideal: http://asteroidos.org/

You know about the Garmin watches, right? They'll do navigation and (some) message notifications.

Polar, TomTom etc have similar devices, but Garmin are probably the default choice.

Thanks, I've used Polar HRM since the late 90s, and then switched to Suunto GPS-enabled watches.

But I'd prefer something with a bit more features. Something that can replace very very casual smartphone use. Receive a short call, navigate somewhere. And track my fitness all the time, including HRM w/o band and blood pressure.

The VivoActive is pretty nice.

But no mainstream[1] smart watches can replace a phone - they act to supplement it

[1] I think there is an LG watch with a SIM in it, but it has limited availability.

You need to invent a better battery then.

>Thanks to an amazing library called "libhybris", AsteroidOS can re-use already existing Android drivers and be compatible with Android Wear watches.

Do they have a hardware compatibility list?

It boots on LG G [1], but there are no applications yet [2]. The project started recently.
