I purchased this watch several years ago and have been the only owner since I purchased it. All the features I used on the watch still work e.g. heart rate, GPS functions, Garmin golf, steps, other running metrics. I am not aware of any loss of function with with the watch. There are a few scratches on the screen as well as the watch case, please see photos as I was able to show the scratches in the photos. They do not inhibit your ability to see the things on the watch face. It's only under certain lighting conditions that they become more noticeable. I have used the watch in pools and it maintains it's water proof properties. I will ship the watch with the original charger. If you would like more information about the watch, please see the below link that gives you a detailed overview. This is the basic model, does not have the sapphire screen. I do not know if it has any of the maps/topos you can see from the website. I never used that function on the watch.
