Oura Ring Gen 3 – Black Heritage Includes Ring, Black Protective Cover, Charger & Charging Cable Pre-owned Oura Ring Gen 3 (Heritage style) in black. Fully functional and ready to use. If you wear a size 6.5-7 on the finger you plan to wear the ring, it should fit you perfectly- unless you have larger knuckles trouble wearing regularly shaprd & sized rings. The ring shows visible surface scratches from normal wear (see photos), but functionality is not affected. A black ring cover is included, which significantly improves cosmetic appearance and can make it look nearly new when worn. Battery life currently averages approximately 1.5–2 days per charge depending on usage. I typically charge it for 15–20 minutes in the morning and about 20 minutes in the evening, which maintains consistent performance. Tracks sleep, readiness, heart rate, temperature trends, and activity Same app functionality as newer models Charger and USB charging cord included Requires Oura membership ($5.99/month) This is a great option if you want to try Oura before investing $400–$500 in a newer model, or if you’re looking for the benefits of a premium smart ring at a fraction of the cost. Condition: Used – fully functional with cosmetic wear.
