Ultra-rare vintage item. The color is silver, with a navy blue dial, and it's an ultra-rare color for an analog-digital watch. This is a must-have item for collectors. It looks black in the images, but the actual color is navy blue. This is a very old watch. There is aging. You should assume that the waterproof function is no longer working. Used item, there are scratches etc. due to use. It's quite beautiful and in excellent condition for its age. (Please check the images) It's rare to find a model from about 40 years ago with all functions working, so don't miss this opportunity. It's really not available. Battery replacement date unknown. As of 2025.8.25, it is working normally. Analog watch I have confirmed the digital light, hourly chime, alarm, stopwatch, etc. It also makes sounds. Press the center button to change modes. Pull the center button one step and turn it up and down to change the numbers. The top button is for the light and stopwatch start. Press the top and bottom buttons together to switch between 12-hour and 24-hour formats. The bottom button is used for ON/OFF and stopwatch reset. You can turn the chime and alarm ON/OFF by pulling the center button one step and using the bottom button. It's difficult to explain in words. I apologize if I'm mistaken. The battery has a lifespan, so please consider purchasing it soon. Please check the condition in the images. Free size belt. I believe the belt is also the original one. Used item. Stored at home. Collection. For those who understand, Thank you. Movement: Quartz (battery-powered)
