The G-shock arrived promptly and in perfect condition. This is a good looking watch especially for a G-shock. The sub-dials {as others have mentioned} are a little hard to read. The band is decent but a little tricky to adjust as the pins are on the inner connecting link-watch youtube for help. The main features that I like are the solar power, the analogue hands, the metal case all combined in the tough G-shock package. I am happy with this purchase.
