I have this watch and it is awesome! Recommend it to anyone interested in a well built fully featured solar chronograph. The only issue is that I did not buy from Amazon! A third party has jacked up the price because it is in limited quantity (I talked to them personally). $600 is over $100 more than the suggested resale from Casio. Not sure why Amazon permits such but be that as it may, I purchased this elseware at $500 and it was instock. Goodluck...
