It's a skeleton (part). There is no main body. I bought it as a spare part, but I don't think I've used it, and it's almost unopened. I think there shouldn't be any problems, but please be aware that there may be age-related deterioration due to the product's age. G-SHOCK #CASIO #Casio #wristwatch #bezel G-Shock #GShock #GSHOCK 47
