Junk item: A G-SHOCK digital wristwatch with shock resistance, radio wave reception, and Tough Solar. It was fully charged by sunlight, and the date and time were automatically adjusted via radio wave reception. However, the display disappears when left away from sunlight. The display reappears and the time is correct when exposed to sunlight again. The photos show the watch in working condition immediately after a full charge. Also, the upper right button is damaged and cannot be pressed (see photo 6). The secondary battery is from the original time, so it may be degraded. Also, it is an old item and has signs of use, so please understand this (scratches, dirt, etc.). Please understand the above points. The quality is not guaranteed. <Basic Specifications> - Brand: CASIO G-SHOCK - Model: Digital Tough Solar Watch GW-600BJ The G series - Features: Shock resistance, 20-bar water resistance, Tough Solar, Radio wave reception - Material: Metal band, metal case - Color: Black - Accessories: None The ultimate in practicality, the phantom "The G."
