G-Shock is a Japanese brand, but not every model is made in Japan. The country depends on the exact model.
A brand being Japanese does not settle where a watch is built. That is why this site checks each model's own listing.
See the watch we found on the watches page.
Are all G-Shock watches made in Japan?
No. Some models are made in Japan and others are made elsewhere. Check the listing and the case back of the exact model.
Which G-Shock is made in Japan on this site?
The G-Shock GW-5000HS-1 Heritage digital watch. Its Amazon listing title says Made in Japan.
How do I check a G-Shock?
Open the Amazon page, read the title and bullets, and look for Country of Origin under Product information. Then check the model number against the Casio page.
