Worn for one year. Slight scratching on ring, the gold has worn off in the back of the ring where no one sees it. Please see all photos and video for gently used condition. Horizon style. Never worn in water though it is waterproof. Holds charge for daysss. Works perfectly. I learned what I needed to learn about my sleep habits and it was absolutely essential! Paid $500 for this newest model and gold finish. Comes with charger and box. Check ring size for Oura. Ring sizer kit in separate listing.
