Hello, I have been offered to buy an Apple Watch first generation (I think that it's called Series 0 and not Series 1) for a cheap price. Is it worth paying for a 2,5 year old watch or should I pass? I have never owned an apple watch and use regular watches so I would probably use the Apple Watch mostly for workouts (running biking walking etc) and stuff like that. Would the first gen be enough for that? Could the series 0 work for workouts without me bringing my iPhone with me? and can it play music to bluetooth headphones stored on the watch?
