Still Casio quality but with a big BUT: not readable especially solar charging system shows no batteries at all effective: we need a daily exposure time very important to get to use its normally watch. While less than spend his days lying in the sun (we all dream!), I do not see how to use this watch. Any solar technology is to review (while in other brands it does not work too badly). As for the legibility of the dial, it is the same problem on all Casio models using this backlight. Again ... you better be nyctalope usual features Casio but still very complicated to set time zones and especially to activate an alarm.
