This is a CASIO Pro Trek PRL-20WVJ-2T. It's a limited edition model in collaboration with WWF. It features a blue camouflage strap and a sea otter appears in the backlight. I purchased this item a few years ago as a new, unused item and have only displayed it as part of my collection; I have never used it. Since it is unused, there is no damage such as dirt, wear, or fading on the camouflage strap. I believe this is a rare model that is rarely seen nowadays. I have replaced the battery with a new one before listing it. The only item for sale is the main body, without any accessories. I live in a non-smoking and pet-free environment, so there is no concern about odors or stains.
