Modern Matte Black Oura Smart Ring

This item is an Oura Smart Ring, specifically the 'Heritage' model known for its flat-top design, though viewed here from a top-down angle that emphasizes its circular profile. The exterior is finished in a matte black, likely a 'Stealth' or 'Black' PVD coating over titanium, which is the standard material for these devices to ensure lightweight durability. The inner band reveals a dark, non-conductive medical-grade plastic or epoxy molding that houses the micro-electronics. Visible along the interior rim are the characteristic raised sensor bumps—infrared LEDs and NTC temperature sensors—used for tracking heart rate, respiratory rate, and body temperature. The item appears to be a modern piece of wearable technology, likely less than three years old. Regarding condition, there is significant visible wear along the outer edges where the black finish has been rubbed away due to friction, exposing the silver-toned base metal beneath. This 'scuffing' is common for matte-finished smart rings. The inner sensors appear intact, which is a key quality indicator for functionality. No specific maker marks are visible in this orientation, but the unique sensor layout is diagnostic of the Oura brand.
