In 2018, G-Shock Japan offered a restoration service for vintage DW-5000C and DW-5600C watches. An expanded limited-time restoration service is now available for more vintage square models.
The service costs 10,560 yen per watch (plus return shipping fee) and includes the replacement of the bezel, band, and battery. The service also includes a special display box featuring a message from G-Shock creator Kikuo Ibe. The service will run from October 5, 2021, to January 18, 2022, and is available in Japan only.
The eligible G-Shock models include the following: DW-5000C, WW-5100C, DW-5200C, WW-5300C, DW-5600C, DW-5800C, DW-1983, SWC-05.

It may be possible for overseas customers to apply by using a proxy shipping service that provides the user with a unique Japanese mailing address, but we are unable to recommend any. During the 2018 restoration service, Hong Kong store Watch Outz offered a proxy service for it, but we don’t know if they will be offering it again. (Update: They are.)
