The Casio PRW-5000-1ER is really nice. I almost ordered the titanium version, but am delighted my first choice. It is large but not excessively (and I have small wrists) and very light. The manual is a little scary in the beginning but its thickness is easily accessible. Essentially then tweaks the watch works alone. At that price you have a compass, altimeter, barometer, atomic clock (auto update once a day) and it fixes every hour to stay second. In addition to 5 alarm, stopwatch, timer, world clock (switchable for travel abroad) and a mode where it stores the altitude records (max altitude, total ascent, total descent, Total Cumulative)
Oh, and as it is solar, batteries needed ... more
My only complaint would be that although it has a éfficace LED lighting, it has no phosphorescent needles. And I spend my time watching but I forget to read the time, making my wife laugh a lot.
