CASIO Casio, digital wristwatch, model CSN-011, CSTERNA Cistena, wrist size approximately 15cm. Buttons function normally. Backlight illuminates. ■ Condition There are minor scratches, but it is in relatively clean condition without any noticeable scratches or stains. The battery was replaced on January 10, 2026 (Reiwa 8.1.10), and the light function has also been confirmed. I think it will make your wrist look very beautiful.
