For sale is a pre-owned Oura Ring Gen3 Horizon smart ring finished in dark matte Stealth, size 12. Hardware performance tracking diagnostics and automated interface syncing logs register the following technical parameters:

• Internal Logic System Integrity: The underlying operational sensor cluster is 100% fully functional. Bench diagnostics verify that the research-grade optical PPG sensors, finger temperature nodes, and 3-axis accelerometers capture bio-telemetry curves flawlessly. The ring establishes high-speed Bluetooth communication with the Oura mobile app environment, completes firm data package sync routines, and accepts firmware updates over-the-air. The miniature internal lithium-polymer power cell holds a normal multi-day continuous runtime discharge curve.
• Heavy Exterior Scratching: The exterior aesthetics display heavy cosmetic wear and visible physical abrasions. The outer dark matte Stealth finish layer shows deep surface scratches, uniform scuffing, and distinct rubbing wear patterns along the perimeter borders from standard daily contact with surfaces, exposing the lighter titanium underneath in multiple spots. The inner hypoallergenic seamless molding resin is intact, slick, and completely comfortable against skin profiles with no splits or cracked sensor housings.
• Proprietary Charger Deficit Notice: Please note that the original circular charging cradle dock is completely absent from this package. This item tracks strictly as the standalone ring module. To deploy, charge, or initialize setup sequences for this ring, you will need to source an authentic or compatible Generation 3 Size 12 Oura ring charging base separately.
• Account Initialization Status: The unit has been successfully cleared of historical personal telemetry tracks via full system settings wipe, unlinked from active subscriber portals, and prepared for fresh user configuration profiling.

FULLY FUNCTIONAL CORE HARDWARE MODULE. Structural titanium frames have never been compromised. This listing tracks strictly as the SMART RING HEAD ONLY without retail boxes, manuals, or charging bases. OUT OF WARRANTY.
