The course is no clock to limbers, but rather a fairly nondescript member of the genus LCD watches. Nothing to it, which would be particularly aufmerksamkeitsheischend - discreet black, almost everywhere. The housing is plastic. I can not say yet whether dyed or painted. The band also Kunsttoff, very thin, very light and a little elastic. The length should be sufficient for each; with very slender wrists you will probably cut the ribbon a little. The comfort comes in Ordung; I know as far worse in more expensive watches. The clasp is a simple one-hole design and a bit fiddly to use, as the design is just as has per se. One notable improvement is that the plastic transparent panel now flush with the casing at an altitude. Owners of older Casio watches know the problem that sooner slightly protruding disc scratches downright has attracted. The tightness class is 50m - allowing, realistically, showering, bathing and swimming. That's enough for me. This clock keeps in materials and workmanship from any comparison with the 200 G-shock Boliden. But hardly the wrist you can feel it, and that's what I wanted above all. The functional scope is reduced accordingly compared to my "big" Casio watches: Week, month, year, time, 24h, perpetual calendar all there. The lighting by 2 LEDs (right / left) are better light than the miniature lamp that was standard in older models and you do not keep the button pressed continuously even; The light remains on for about 2 seconds after pressing. These LEDs can optionally additionally also visually a full hour, signal an alarm, or the end of a countdown. Only visually, without beeping, does not seem to be possible, A multifunctional alarm is present, the optional reminded every day at a certain time, the whole limited to a particular month, or a specific date. There is also an hourly chime, for the one who likes it. Everything simple piezo beep signals, rather discreetly in the volume. There is also a countdown timer that can be set between 1 second and 23h59m59s. These can be selected once, or ever be repeated. A mode for a second time zone is missing. The stopwatch measures 1 / 100ths of a second to 23h59m59s, also allows split times. That's it. The whole operation is, as well as setting the time, Casio-typical and is no mystery if you a little experience with these watches. If not advisable because of the quite ordinary functionality, read the multilingual instructions that come with the block. I paid 16.92 for this very inexpensive clock and will not annoy me, therefore, a long time if I should lose it somewhere once. Also an advantage.
