Pebble does not have GPS at all. You don't have to use GPS on the watch, if you don't need to. You have an option to choose to use it, if you want to. Garmin watches ~2 weeks just as a smart watch, 8-50 hours with GPS on. But you will not have it on, unless you need it for a specific workout.

Garmin's Enduro 3 claims 13.3 days[1] of continuous GPS tracking with solar recharge and is tested to have 5 continuous days without[2].

I get about two weeks from my Garmin Instinct, using GPS sporadically as needed.
