About The Specifications Catalog

Please note the following:

1. The Specifications Catalog is for informational purposes only and is maintained by G-Central, an independent fan site. We do not sell any watches and we are not managed by Casio.

2. The catalog is intended as a shopping supplement to help buyers research and compare different G-Shock series and browse new releases. The catalog is not meant to be a complete archive of every G-Shock series or model ever made, but we will continue to add images and article links for new releases. Some discontinued or Japan-only series may not be listed. (We aim to list all active series in the U.S. as well as popular import series.) If a series has used multiple modules, our specs may reflect the most current module. Prices are in U.S. dollars unless otherwise stated. Series without a price listed in dollars are those that either haven’t been released in the U.S. yet, are import-only, or discontinued. Some series and models listed may not be available in the U.S. or other countries. New models added to the catalog may be pending release.

3. The price and specifications are for the individual model pictured or stated in the series description. The prices and specifications may vary in a series, depending on the individual model. Examples of specifications that may differ between models include material type, weight, and Neobrite luminous hands. Models with different materials, special surface treatments, and limited editions may have a higher price.

4. For more in-depth information about a series and all of its functions, follow the module link to view the official instruction manual from Casio.

5. The size (S, M, L) categorization is based on the overall look and feel of the watch and is not necessarily based on strict measurement thresholds. We generally categorize G-Shock watches that are over 50 millimeters wide as “large” and under 50 millimeters as “medium,” but this may not always be the case.

6. In the case of discrepancies between our specifications and the official Casio G-Shock site, we suggest also looking at the “Specifications” section at the end of the instruction manual for the series’ module. We have noticed some errors on the official Casio website, and we often base our specifications on the instruction manuals rather than the website.

7. Specifications are subject to change without notice. We recommend cross-checking information with Casio.com and the specifications listed in the instruction manuals.

8. Please contact us if you notice any errors or problems. We appreciate the time and effort taken to notify us.

About Our Ratings:

The ratings for each series are evaluated in comparison to other G-Shock series. Our overall ratings are based on a combination of three factors.

Build: Includes the materials used, structure, and overall design of the watch. A series with the same materials as another may receive a higher score if it is a classic or popular design, or if we feel the design is especially attractive.

Functions: Includes the overall features and functions of the watch.

Value: Based on the build quality, design, features, and functions available in relation to the price. If a certain series or model can regularly be found at a discounted price, we may take the discounted price into consideration over the list price.

Ratings are subjective and are subject to change.

Feel free to leave your own rating and review under the “Reviews” tab for each series.
