I went from no watch to a Samsung S3, to an Apple 3, to a 4. The jump from 3 to 4 felt substantial. The 5 and 6 never did much for me. I wear my 4 most days but I often didn’t with the threes. I’m considering a 7, because of the larger screen and because of the always on display.I have a 3 and honestly have maybe worn it less than 30 times... at least I got it refurb'd. One of the worst apple buys I've done.
But you’re right about not wearing it. It’s was my biggest hurdle.
