I have gained this clock as a "work watch". With the clock like it very well for this purpose! All information about your family are clearly visible. The light has a clear view even in the dark. Very pleasant I find comfort, because the clock is very easy. This is, however, perform back due to the plastic disc. The disc is very empfindich. My clock is now 4 weeks old and first scratches are already visible. I appreciate the life of this clock in my application on about a year!
