This watch model is very beautiful! But unfortunately not useful as CLOCK. Since this model can only be operated via sensor keys, you can in the winter (with gloves) do not operate. Add to this that the display only the Puma logo and not the time anzeigt.Dies is also, according to information from Puma not be switched off and, according to their statement a publicity stunt !!! So, a buyer should want to read a time, so you should resort to a different model and manufacturer.
