All you have to do is take a survey, and apparently your warranty is extended for an additional year. It’s not clear whether you have to register your watch, as well, however I would assume so. Registration can be completed online right here.
While I have the attention of G-Shock fans, witness the evolution of the G-Shock through this interactive timeline, or take a peek inside a G-Shock watch.
Would like to extend the warranty on my g shock watch,pls help with the procedure
