For those of you who don't have a built in clock in your instrument cluster, how do you usually tell the time while you're riding? Like, if you're going for an appointment, how do you check your progress and make sure you get there on time? When I'm driving my car, I constantly keep track of the time to make sure I arrive at my destination on time, but when riding my bike... I have no clock on the bike, and my watch is under my jacket, which is under my glove... I've seen clocks made to clamp onto the handlebars, but all the ones I've seen are really rather expensive! What does everyone else do?
