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 🙂

Functions Rating Calculations
*we took all common features in the Gravitymaster ANALOG model range (from new watches to old watches) and listed them in the table. Some features have more power (like Tough Solar or G-Shock Bluetooth technology) and they receive more points than others.
| Functions | Points |
| Tough Movement | 1 |
| Tough Solar | 2 |
| Radio-controlled Watch; Multi band 6 | 1 |
| LED light | 1 |
| Timer | 2 |

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.

| GPW-2000 | 840 | ★★★ |
| GPW-1000 | 1160 | ★★ |

| GW-A1000 | 490 | ★★★★ |
| GW-4000 | 325 | ★★★★★ |
| GW-3000 | 305 | ★★★★★ |
GW-4000 GW-3000
*Although some watches may have the cheapest price, they may not get the highest rate because of poor functions rating.
