This is a serviced Casio watch! It's an A410-T000193, featuring solar charging (Eco-Drive) and radio wave reception. The watch has a sophisticated feel with its heavy black case and simple Arabic numeral dial, making it suitable for both business and everyday use. It's a user-friendly watch with features like a date magnifier. *The internal battery may be depleted as the battery has not been replaced. It is currently working, but please be aware that you may need to replace the battery after purchase. Also, I have confirmed that "NO" appears during radio wave reception.
