This high-quality watches Dreher is processed very nice from the outside. The elegant black leather underlines its high quality. I bought exactly this Dreher, because it works with batteries and is therefore working from anywhere. However, the power supply is not present and have to be purchased if desired separately. Inside the clock is simply a platform with spring adjusting to the lead size, clamped. Personally, I find this rather simple fall, but it served its purpose. The unit is completely silent and not listening. Top! What bothers me personally is something that the clock is not located after your rotation back into an upright position, but always different, diagonally, on the head, and so comes to a halt. That's not bad in terms of function, if you but your clock every now like to consider again, it bothers already if he is standing on a top hat. Therefore, I only 4 stars. But otherwise highly recommended!
