In order to compose [what we think] a statistically significant G-Shock Rating System, we needed to go deeper into technical specs and compare them within the relevant watch collection. In the very case, we took all G-SQUAD watches with Phone GPS function and started comparing details. We stick to the point you are to know our rating calculations methods since it is not a black box [like in most services & shops] and you may find new details about other watches. Hope you will like our tremendous job and will continue using our magazine in your current and future purchases 🙂
