I carry a cheap Timex "indiglo" watch, with hands, about half the time. I'm more interested in "daylight" than knowing the actual time. Overcast days make it harder to judge sundown and a watch makes it easier. I do use the "hands width at arms length" method, even when I'm wearing a watch. Figure about 15 degrees per hour and your hand is about the right width for that. Funny...the indiglo face is actually bright enough to use as a light in my hammock.
