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 Gravitymaster case, we took all ANA-DIGI watches (as they use a similar caliber development approach) and all ANALOG Gravitymaster series (separately from ana-digi of course) 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 🙂

Price Rating Calculations & Winners & Losers
*we took Japan’s official price and converted it to USD. The price may not be the same as on Amazon or other marketplaces, but it is good for building a representative rating system.

| GR-B200 | 350 | ★★★★★ |
| GR-B100 | 352 | ★★★★★ |
| *GA-1100 | 258 | ★★★ |
| *GA-1000 | 200 | ★★★ |
| GW-3500 | 400 | ★★★★ |
*Although some watches may have the cheapest price, they may not get the highest rate because of poor functions rating.
