The clock is pretty, not too powerful, very well made and has a high quality appearance. It's my first solar watch. Dim, artificial light or weak lights are not sufficient for charging. But until now the clock is ticking dependable (to charge up through light bulb, but unfortunately was not much sun the last time). In addition, the clock is splash proof (s. Description for waterproofing). Downside is that it is the watch glass only "Hardlex" (more or less standard glass). Sapphire crystal course I would have preferred, for the price but have wished a little too much. I therefore do not expect that the clock will long remain scratch-free. The disadvantages are, however, to read all the description. Dimensions of the case appear to have helped me earlier estimate the size of the clock. Am very satisfied.
