I am new to the G Shock watches. As I have done some research, it seems you get a lot of watch for the money. The problem is there are so many models and so many additional letters or numbers with each model. I have been looking at the above three models, but wanted some expert opinions. Please give me your thoughts on the above three or other similar models you have purchased. I am also not sure on battery or solar/atomic. I am leaning towards the battery models at this time. Thanks in advance for your comments.
