The design of this clock is somewhat problematic to my taste. It is supplied with a white bracelet which also can not be replaced. It acts on the wrist very rough. This clock can be in professions where you want to make a confidence-inspiring impression on people who do not wear my opinion, but in occupations where you can get a shock quickly, it can be used. Likewise, as a clock underwater because it is waterproof. The clock has a lot of ads. Among others she has the ability to stop time, making it usable in all situations in which you do not want to expose the harsh weather his cell phone. She also has an alarm clock. And it shows the date. You can choose between the display of the normal time and the switch between day and month. The date format can also be adjusted as needed. Then there's a countdown timer and it is possible to program a second Zeitz Without. I think that has a lot of contact to USA and the possibilities Zeitz horsegram must remember, very useful. Also you can let illuminate the clock, the manufacturer says in fairness to the fact that this may be hard to see in direct sunlight. Last but not least, there is of course still Clock ... A very well-drawn instructions helps to learn the various functions. So I have to say that the price I find accordingly processed very well overall the clock and it has many useful functions. But on the wrist it acts powerfully fortified. It takes a very broad man's arm, so as not obtrusive. I personally do not find them beautiful, but meticulously crafted and useful. I do not like the plastic strap. But that's a matter of taste. So, overall a clock for people who want to dive or a lot of wind and weather exposure, but it is good or as Zweituhr for the holidays if you want to leave for safety reasons, the good clock at home and while camping may be write clock needs. For all such situations a sensible clock with many possibilities, acting just a bit clunky.
