For these reasons, for me, Pebble was the only smartwatch that appealed to me, hardware-wise, but it's worth noting that the ToS on their Pebble software is ridiculously anti-privacy. There's an alternative app on Android that is privacy-conscious (gadget bridge), but it's still a work in progress (and they have to reverse engineer everything on the device).

I'm still happy enough with being able to more or less customize my watchface, but if you both care about your privacy and want to make serious use of the "smart" smartwatch features, I don't think there's currently anything on the market for you.

This would have been my response. I've got a Pebble and I charge it ~2hrs a week and the time is always visible.

Can you make payments with the Pebble? Turn on the computer when you come in proximity?

No, but for parity with a standard wrist watch the Pebble is your best bet.

You can auto-unlock an Android phone with the Pebble via stock Android. (no passcode required with a Bluetooth connection to a certain device)

No.
