Classic looking watch

Looks a million dollars! Beautiful time-peice and great size on the wrist. My partner loved it. Highly recommend.

Functionality and durability in a very pleasing package
14 October 2020

This watch has a very modern and tasteful design compared to most toolwatches. Of course, with all of the benefits of functionality and durability of a G-Shock. Form meets function. Band is extremely comfortable and the watch sits low on your wrist so it doesn't feel too big.
