Wooden gears rotate to display the day, date, and month. No batteries. No screens. Just a precision mechanism you assembled yourself, sitting on your desk, doing its job beautifully.\u003c\/p\u003e\n\n\u003ch3\u003eThe desk piece that actually does something\u003c\/h3\u003e\n\n\u003cp\u003eMost desk decorations just sit there.
