For $450 you can have Instinct 2X Solar, which is a very useful tool watch, surprisingly functional without phone connection and with a month of battery life. Can probably be used without ever connecting to a smartphone, I'm not 100% sure but everything seems to be configurable from the watch itself. Almost useless for reading text messages though. Basically a polar opposite to Apple Watch for a similar price. Pebble is nice as a concept, with E-Ink and easily programmable watchfaces, but its hardware is arguably quite ugly, and has way less sensors.
