This is a CASIO Wave Ceptor wristwatch. It's a solar-powered, radio-controlled watch and is currently working. I'm selling it to clear out my collection. ○ The time is mostly accurate. However, despite being a radio-controlled watch, it's inexplicably running one minute slow. The cause is unknown. This is for those who don't mind a one-minute difference or can fix it themselves. ○ Wrist size is approximately 16.5 cm. Adjustable. ○ Lug width is 18 mm. ○ Case size is 42 mm, including the buttons. ○ Color: Black. ○ The rechargeable battery still has plenty of life. Thank you! Please understand that this item is stored and inspected by a private individual and is a used item. There may be oversights that a non-professional wouldn't notice, so please purchase with that in mind. Please refrain from purchasing if you are overly concerned about minor details. #wristwatch #watch #CASIO Operation...Good
