A blue digital wristwatch from CASIO MT-G with shock resistance. - Brand: CASIO - Model Name: MT-G 510 2339 - Color: Blue - Material: Stainless Steel - Features: Shock Resistance Wrist size: Approximately 16.5cm Battery replacement is required. It was working normally before the battery died, but it is currently not possible to confirm its operation, so please understand this before purchasing. I didn't use it every day, so the screen has no noticeable scratches or dirt. The band has some minor scratches. There is no case. The watch only. Please refer to the CASIO website for the manual. Thank you for viewing.
