This is a serviced Casio watch! It's a WVA-M600 model with radio-controlled solar power. The gray and black dial with an analog-digital display offers high visibility, and the versatile design is suitable for both business and casual wear. The silver stainless steel band gives a calm impression and naturally fits the wrist of an adult. *Since the battery has not been replaced, the internal battery may be depleted. It is currently working, but please be aware that battery replacement may be required after purchase. Also, I have confirmed that "ERROR" appears during radio wave reception.

Because it is a used item, it is difficult to perfectly convey all the fine scratches and dirt. Regarding the colors in the photos, the subject may appear different from the actual color due to the shooting environment and viewing environment.
