I still have the series 5 in stainless steel. After 4 years, I recently received "battery service", in which they just replace the whole watch. I still like it.

I still have the series 5 in stainless steel. After 4 years, I recently received "battery service", in which they just replace the whole watch. I still like it. Biggest downside for me is one of the more recent watchOS versions they introduced roughly a year ago. To this day, sometimes the notifications can't be dragged down and the display seems to be unresponsive once every 2 weeks for a while. If you get a new watch, beware of the Milanese loop: it tends to destroy the fiber of long sleeve shirts.
