Among all the current G-Shock models, two color really stands out recently - yellow and white. Of course if you are looking for the most popular models for these two colors with a reasonable price (or simply cheap G-Shock) watch, you should look no further than the G-Lide white G-Shock GLX5600-7. Alright, this model does not come with the yellow color.
So, what you really are looking at is the G5600A-7 white tough solar G-Shock and the G5600A-9 yellow touch solar G-Shock.
These two models are so popular, reliable, and dependable that Casio make their sister variations as part of the Go Green Collection.
