CASIO G-SHOCK navy digital wristwatch with solar charging function. It's old but still working. The band shows signs of aging. I haven't checked the inside of the watch, so I don't know if there's any rust, but it has been running for nearly 10 years. Please understand and purchase. - Brand: CASIO - Model: G-SHOCK - Color: Navy - Features: Shock Resist (shock resistance) - Solar Function: Solar charging - Digital Display: Digital display - Band Material: Plastic
