End your dependence on your smartphone and use the Retro Analogue Flip Clock from Schoolhouse Electric & Supply Co. Marvellously retro yet entirely practical, this numbers on this clock physically tick over as times goes on. Powered by a 1.5V battery, the Flip Clock gives you all the information you need without disturbing you with notifications. In addition, it uses a quartz German movement to ensure the time kept is ultra precise. Made of durable plastic, the hours section features an AM/PM indicator to keep you informed. Measuring 7 inches, this clock is modest in size and comes in black and white to not overpower your nightstand. Overall, its humble design and exterior take the backseat while the numbers remain on full display.
