Tokyo Clock brand, 7-jewel hand-wound stopwatch. A Showa-retro stopwatch. The dial is simply amazing. One revolution is 30 seconds, with a 15-minute counter. It's a hand-wound type, so you use it by winding the crown on top. Like a typical stopwatch, press once to start, again to stop, and reset with the button on the upper left. There are scratches overall, but it has a nice vintage feel. [Included Items] Strap [Size] Diameter: Approximately 5.0cm Thickness: Approximately 1.5cm Weight: 72g Please allow for some margin of error. [Condition] There are some minor scratches, scuffs, and dirt from use and aging. There is some rust on the back. It's old, but the crown rotates smoothly, and the mainspring can be wound. Also, the start, stop, and reset operations work smoothly. (Operation confirmed) The photos mainly show noticeable scratches and dirt, but there may be minor scratches that are not visible in the images. Please refrain from purchasing if you are looking for a perfect item, as this is a used item. Thank you. #Stopwatch #TOKYOCLOCK #ShowaRetro
