SO, long story short, my son comes home from college for Fall Break and has his ?Watch Series 3 Nike Edition that we bought him for his birthday. He forgot to bring his charger so he takes off the watch and puts it on his nightstand. Later on after returning to school he says, "Oh, yeah, I left my ?Watch in my room." Since he was flying out to Albuquerque for his cousin's wedding we figure we can pack one last little item, and remind him, "don't forget your watch charger" (which he did, of course!)
Well, I try it on as we're leaving and press the crown. Two seconds later I see the current time (in red) and a red lightning bolt, which I take it to mean that the ?Watch is running on fumes. Now, this is like three weeks after he forgot the watch, so I expect it to be totally spent and unresponsive, but it still could light some OLED pixels to show the time, like one of the original red LED watches from the 1970s. In other words, it still functions as a timepiece.
Anyway, I wore it on the flight to ABQ and out to dinner the next night. I found that the 42mm size was about right, not as big as I thought it was going to be, so my thinking of getting a 40 mm ?Watch Series 4 after the EPP discount kicks in seems sound.
