Carpenter’s Square

Why bother putting a *hinge* between the minute and hour hands? They might as well stay fixed at a right angle. We'll just move and rotate that square corner around to point at the right places, though we will need to flip it over sometimes. Inner edge of thick arm is hour hand, thin arm is minute hand; look at where they intersect the marker circle. Digital time added grudgingly; tap it to toggle its visibility. Left-hand gauge is watch battery; right-hand is for phone. A little blip of a second hand moves just outside the inner circle.
