is prima ne clock and was cheap with under 20 Euro, the lights at your fingertips in the dark so is the illuminator, at night when you want to see what time it is, of the 30 storage is great for phone numbers or bank information, even though that one day looks in english believe you can not change the German dayNames, but the date and year is also always seen, stopwatch is on, several times in the alarm bell. not strike for the price. I fnde it is the most practical casio clock. nice and flat, does not interfere with the joint. probably also waterproof, I test but do not think he as all eventually problems when water too long rankommt .denk but possible to go swimming with the would that too, too bad that the clock there were times earlier with a 50 and 100 data storage, the were set. a pity, but the 30 store here in the clock's enough basically for the most important data.
