The TFA Germany MARLEY Wall Clock with its dial made of real slate brings both a natural and elegant flair to your home. The unique texture of the stone makes each clock one of a kind. To retain the natural beauty of this wall clock, the hour markings are discreetly engraved on the dial. The original hands made of walnut wood complement this. The key component of the clock is also impressive with its quality and sustainability. With a deviation of less than 0.5 seconds per day, the energy-saving quality movement is much more accurate than other commercially available quartz movements. Thanks to its long battery life, the batteries only need to be changed every three years or so. The hands glide almost silently over the dial and do not disturb you with annoying ticking while you are sleeping, studying or reading.
