In order to compose [what we think] a statistically significant Casio Retro Rating System, we needed to go deeper into technical specs and compare them within the whole watch collection. In the Casio Retro case, we took all Casio Retro Series 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 🙂
