Brand: Casio Product Name: PRO TREK 3207 Model Number: PRG-110CJ In recent years, I haven't used it much because I've been using mountain climbing apps. Therefore, I would like to sell it to someone who can make good use of it. The original box and instruction manual are not included. Also, as it was actually used for mountain climbing, there are signs of wear, such as scratches and exposed metal on the corners, as can be seen in the second image. Please confirm these points before purchasing. The instruction manual can be found on the web. Reference: https://support.casio.jp/storage/pdf/002/qw3207.pdf
