This is a set of 4 watches, including TEKNOS. They were working fine before the batteries died. I believe the batteries are dead now, and since I haven't replaced them, I'm selling them as junk. They are generally scratched. There are also scratches on the glass that are not visible in the photos. Some parts, such as the areas circled in red in the images, are missing decorations. Please make your judgment based on the other images. These are used items. Please refrain from purchasing if you are sensitive to imperfections.
