After my old clock after 8 months a battery change was required once again and I felt the eternal setting of date, and setting the summer / winter time on my nerves I was looking for a new one. Acquired Casio looks really good, athletic and classy. They came with the wrong timing and I therefore had to at the very beginning by, for the eyesight of an eagle designed, accompanying description read (only downside: less really go well no more!). The automatic time setting worked right away in an area where the reception is usually rather poor. It runs flawlessly for days, time is right, joined in time change. The battery is in spite of office lighting and suit full always. Preliminary kudos. Whether it is waterproof, it will turn out on vacation. Considers how long the battery, we will still learn. Shortening the bracelet was for me (wearing glasses) it a bit problematic, but even that went in a timely manner. So far: Value for money is good, look great, for me strong buy recommendation
