Fossil, Garmin, and (to an extent) FitBit work in different market segments to Apple and Google. Fossil leans heavily on its brand value and aesthetic, while the other two are more fitness centric. The Apple and Google entries are general purpose tools.
Pebble was a different market segment too. Pebble was a low cost, long battery life device. There still isn't anything remotely like the Pebble Time on the market right now. I literally went 2 years looking for a similar device after my old Pebble died and couldn't find anything before giving up and buying an Apple Watch. I do like my Apple watch but honestly, I'd rather have had a new Pebble Time.
