CASIO G-SHOCK's most popular speed design model, a solar-powered radio-controlled watch! I think the condition is beautiful (^^) Since it's a radio-controlled watch, you don't need to set the time, which is very convenient! I purchased it used, so I don't know the details such as when it was purchased new or whether the battery has been replaced, but it worked fine, so I think there's no problem! CASIO Casio G-SHOCK G-Shock Popular Casket Digital Speed model GW-5600J Tough Solar / Wave Ceptor Radio-controlled watch I purchased it used, so I don't know the purchase date or the remaining charge of the secondary battery, but it worked without any problems, so I think there's no problem. Since it's a radio-controlled watch, the time and calendar are automatically synchronized. I have checked it before listing, so you can use it immediately. I will include a copy of the downloaded instruction manual. 【Condition】 Used, but there are no noticeable large scratches or stains. The back cover is also in a clean condition. However, please understand that there is some wear and tear due to aging, as it is a used item. I think it can still be active for a long time, so please feel free to purchase it immediately (*^^*) #ToughSolar #SolarRadioWave #RadioSolar #SpeedModel #Digital #aGW5600 #Casio A G-SHOCK digital watch equipped with Tough Solar function. - Brand: CASIO - Model: G-SHOCK - Functions: Tough Solar, radio wave reception, 20-bar water resistance - Accessories: With a copy of the instruction manual - Design: Black, digital display Thank you for viewing.
