A week ago I got my Citizen Promaster Eco-Drive in a large and heavy watch box with good protection. It is much lighter than the "old" Promaster with automatic movement, is comfortable on the arm and is, up to the date, very easy to read, especially the elongated and slender minute hand also has a bluish border, which thick the small and hour hand is missing. The hour markers, which are not numbered, are easy to read, and in the dark light, both the pointer and the markings clearly. I chose the Promaster with blue dial and bracelet, because it is 20 Euro biliger than with yellow bracelet. No one knows why. The accuracy is better than indicated:. Indication up to 15 sec / month, measured deviation 5 sec / month + (extrapolated).. By solar cells installed rechargeable battery is charged. A power reserve is to run in complete darkness for half a year the clock, and the battery will last as long as the clock, where you do not know, of course, how long because now holds the clock. All in all I like the clock, and I would buy it again.
