Yes, they are now supposedly released and available. But if you go to their website the earliest you can get them shipped is late February. And it seems to be slipping slowly as time goes by. I have tried going to the store before they open – 7 days in about a 12 day period and have not been able to get one.
But people are getting them. I ran into someone at the Whole Foods Market the other day who had one on. I did chat with him for a few minutes and he seemed really pleased. though the one feature that is really driving me to it seems to not be as important to him – moving from Watch / iPhone to other Apple devices. He seemed quite satisfied moving from his Watch to iPhone back-and-forth.
