These are compatible spring bars, almost the same size as the genuine spring bars for Frogman DW-8200 series and GW-200 series. Common spring bars sold cheaply in sets on Am◯zon etc. have a shaft diameter that is too thin and will not fit G-SHOCKs. These are made thicker to fit G-SHOCKs, so they can be used without any problems. How about it for those who have lost their original ones or want a spare?
