Purchased in December 2017. I bought it for interviews and used it about twice, then stored it in a dark place. When listing it, I charged it with solar power and adjusted the time (date and time), which can be a hassle. The operation is fine, but the leather on the strap shows signs of deterioration, so I think it's best to replace it. It also has radio wave reception, so it automatically displays the correct time, which is convenient. A simple design wristwatch with the box and instruction manual included. How about it?
