Had this watch for some time now. My favourite of the g shock family. It's easy to read keeps time, over a period of months only varied a few seconds. Very durable, and tough. The solar power is great no batteries to worry about, holds charge amazing, had it away in my box for a month only went to M, a few hours in the sun back to H. Highly recommended this watch, I'm in the trade and lives up to the g shock reputation. Can't fault it.
