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. are too thin in shaft diameter and do not fit G-SHOCK. These are made thicker to fit G-SHOCK, so they can be used without any problems. How about it for those who have lost them or want a spare?
