I bought it because it's combines things which I like. Eco-drive, sun driven mechanism, titanium casing - light and sturdy and water resistance up to 100m, which means I can use it even when snorkelling, I doubt I will ever try it though, I like this watch too much to put it to such tests.
There is one thing I'd like to tell you. The photo is not really representative. The watch is much darker as it is on this photo. I actually prefer it darker, it's more elegant this way. I'll try to add some of my own photos to better show you how the watch looks like in different light.
All in all, great watch well worth its price.
