I purchased this from the original seller in a "tried-on only" condition and used it once for a national examination. I didn't wear it; I just kept it on the desk to look at. (By the way, I was able to pass the exam successfully.) I have stored it in its box since then. The battery is installed, and it is working properly. The second hand makes almost no sound, and the simple design is clean and easy to use. ★ Items won at night will be shipped the next morning.
