CASIO Casio PROTREK Pro Trek TRIPLE SENSOR Triple Sensor [Compass, Barometer (Thermometer), Altimeter] PRG-110CJ 【Black x Gold】 This is a tough solar watch with a solar battery. The watch, alarm, and stopwatch functions can be used, but they run out of power within a few days. Also, the barometer etc. are not working, and it seems that the battery capacity is insufficient. There are no accessories. I purchased this used and used it normally a few times. After that, it was left unused. I was thinking of replacing the secondary battery, but I bought another watch and haven't had a chance to use this one. In my subjective opinion, the band has no obvious cracks and I think it's in good condition. Please understand that this is a used item and that battery replacement is probably necessary before purchasing.
