CASIO Calculator Watch Purchased at a watch store on July 30, 2022 No box No light function QR code for instruction manual included I selected "Women's" for the category because I had to choose one, but it has many adjustment holes and can be used by both men and women. My wrists are rather small for a woman, but I was able to fasten it on the second hole from the end. It should fit children as well. Thank you for looking. I bought this watch three years ago and have only used it a couple of times. It is in very good condition. The battery has not been replaced, but it is currently working. The warranty has expired, but I found the warranty card and the instruction QR code paper, so I will include them. It has a calculator function, which I did not use. Please note that as of today, September 11, 2025, the watch is running on its original battery, which is three years old, so the battery life is unknown. I hope someone who understands the above will use it.
