Casio introduced numerous new Classic G-Shock watches at Baselworld 2010, and this watch is definitely among my favorites (this new G-Shock is really nice too). The new Aviation Concept watch (pictured) is part of the Classic line of G-Shock watches, and although the name includes the word "Concept", it is not actually a concept, you can already buy one here. Unlike most Casio G-Shock "Classics", which are made of resin, this watch features a steel case and bracelet. It is a more premium G-Shock than is usually sold in the US market, and this is definitely a good thing. The only downside, is a higher price.
