One doesn't tend to go to G-Shock for a small watch. In terms of cubic centimeters I have more watches from G-Shock than I do any other brand. Nevertheless the CasiOak does fit the bill for smaller to medium-sized wrists. Its case measures 48.55mm x 45.4mm with a total thickness of 11.8mm. Compare that thickness to 13.4mm for Relógios omega Réplica the clear version of the Replika omega klockor DW5600 replica omega watches and 18.4mm for the clear version of the GA700.
