Yes, including the 18-karat gold model.

I’m never buying a smart watch again. I bought into the Moto360 hype back around this same period. The watch was slow as molasses and basically next to useless. The battery wouldn’t last a full day either. You’d look down to tell the time, and it would be blank. So phone out of the pocket, which is what they are supposed to help prevent.
It was the watch that made me realize that I’d rather just have an actual watch. The battery completely gave out on it sometime in 2018, and it looked like a PITA to fix, so now I have this really attractive gold watch with a nice band that’s completely useless. Won’t be handing it down to the grandkids, that’s for sure. I’ve got a nice real watch now, and they can have that.
