What I like about the clock immediately her something edgy and therefore striking case. This comes while nowhere near as powerful therefore, as it is known from other G-Shocks. Superfluous or even duplicate functions, such as the combination of analog and digital time display can not be found here, fortunately. Everything is functional, clear and easy to operate. The build quality is impeccable. The delicate multicolored lettering is a looker. The clock provides a casual attitude to life and accompanies me everywhere, 'even to the theater. A designer watch may be able to look better, but at the latest when the next fashion trend, a successor is coming. In the GW M5600-1ER technological zeitgeist potters of today: a five-frequency radio signal receiver and a solar drive. After unpacking the clock must of course first be calibrated. Who wants to wear the same clock, the time must first manually. The radio signal calibrates the time specified later. Practical: is a long time not enough lighting available, the clock automatically switches to a power saving mode where certain functions are overridden (individual hourly chime or auto-backlight) The signal could be a bit noisy, but otherwise the clock is recommended for people that all want to take their clock: to swim in a mountain lake or the theater. And compared to me another radio Solar watches is the GW-M5600-1ER a real sale! Full marks, of course.
