Sold as a set of two. As of the listing date, October 25, 2024, both watches are working, with the date and day of the week synchronized (the left one doesn't display the day of the week), and the seconds ticking. I have confirmed that the lights on both watches illuminate. I haven't tested the other functions as I'm not familiar with them. From a quick look, they are generally in good condition. For their age, both the fabric straps and the LCD screens appear relatively clean. The left watch is missing the bezel, as shown in the photo. Please note that these are old items, so please understand that there may be age-related deterioration in the future, and there may be some overlooked issues. Please refrain from purchasing if you are overly concerned about these points. As these are watches, the batteries may run out over time. However, they are definitely working at the time of listing, so they should function with new batteries. They will be shipped in a Yu-Packet Plus box.
