The UR-112 aggregat is a mechanical digital wristwatch introduced by Swiss watch brand URWERK. Unlike regular watches, there is no dial, but the side has been replaced with a digital display. You can see the time without turning your wrist, and the night is illuminated by Super-LumiNova metering. In addition, it is equipped with a special effect that allows you to know seconds and a power reserve of up to 48 hours when the top lid is opened with one button.
It is said that the name was derived from the rocket Agrigat, which was made in Germany because of the advantage of efficiency in that power is supplied from one energy source to all apparatuses without waste and some of them are reused. Related information can be found here.
