Apple Watch Series 3 daily. Bought the girl friend a Series 4 for her birthday and she has quite literally not taken it off but to charge it. She sleeps with it to track that; works out with it, etc... Otherwise, for fancy occasions and I don't want to be notified of every little text or email - my collection consists of a Tag Heuer Formula 1, a white faced Tissot (a classic looking watch), an all black Citizens (think it's the night hawk or something like that) and a black Movado.
