Been running a couple of times with the new WatchOS and really like the 'flash / blink' feature the watch now has when running at night. It has three settings: Solid White Flash White / Black Solid Red There are a couple of annoying things at the moment; not complaining, just commenting, it is very new. Currently the 'flashlight' goes to sleep after a couple of minutes ( maybe five ). The battery is significantly hit. I did a short 3 mile run and the battery started at full charge and was down to 58% in about 20 minutes. Turning the flash while running is cumbersome, you have to navigate out of the activity display by pressing the crown, swipe up from the bottom to display the 'dock', tap the flashlight icon, then swipe left to get to strobe. You have to do this every five minutes.
