I purchased this about 10 years ago. There are no instructions. Although it hasn't been used much, there are a few inconspicuous dull spots and scratches. This is a Casio Standard Line QUARTZ digital overseas model with a slightly cheap and retro-futuristic design, like a robot that appears in 80s sci-fi movies, evoking a sense of nostalgia. It's a cute, unisex watch. It has an easy-to-read, simple LCD screen and EL backlight, making it a highly practical, multi-functional watch. It's also popular as a fashion item and is a highly recommended wristwatch with excellent cost performance.
