CASIO G-SHOCK 5600 SERIES GW-S5600-1JF It's difficult to convey in the photos, but there are signs of use, such as scratches on the band from wear. I believe there are no issues with the operation. Please refrain from purchasing if you are concerned about used items. -------------------------------------------------- This is the "RM Series," which pursues shock resistance in terms of material. Through joint development with Mizuno Technics Corporation, a strong band that is difficult to break has been realized by inserting carbon fiber, which has excellent tensile strength, into the resin. Carbon fiber has been inserted into the spring bar area of the case connection, the buckle area, and the band keeper, paying attention to the details. Titanium is used for metal parts such as the back cover, side buttons, and buckle. The back cover is forged to pursue shock resistance and durability. The design is cool, taking advantage of the texture of carbon fiber. GW-S5600U
