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.
I have had two Timex Ironman (Ironmen?) in the last 14 years and the last one survived ten of those years. I really hate charging yet another thing so a ten-year battery life is pretty good (of course it depends on how much you use the Indiglo feature, primarily). They’re also much more durable than Fitbits, which are my only other data point.
Right this moment? A Casio Oceanus OCW-S100-1AJF. I think most high accuracy quartz watches are pretty cool, as is the silver dial Rolex OP Date (34mm), a year-2000-or-so black dial Air King, certain Tissot Powermatic 80 watches, the Grand Seiko SBGR253, the Sinn UX, the Casio MTP-1274, and the Casio GWM5610.
