Oura Ring Generation 2 (Heritage Matte Stealth, Size 11)

Oura smart ring for continuous health and sleep monitoring.  Design & Hardware Architecture * Flat-Top Heritage Shape: Built with a distinct flat balance surface on the top profile, giving it the look of a traditional signet ring.  * Stealth Coating: Constructed out of a lightweight titanium shell coated in a matte black Diamond-Like Carbon (DLC) finish for high scratch and scuff resistance.  * Inner Ring Sensors: Features three tiny, smooth structural nodules on the inside housing infrared (IR) LEDs and a temperature sensor.  * 100-Meter Water Resistance: Safe for showering, swimming, diving, and heavy handwashing.  Biometric Tracking Metrics * Sleep Quality Index: Deeply tracks your sleep stages (REM, deep, light) alongside resting heart rate and respiratory rate to calculate your nightly Sleep Score. * Body Temperature Tracking: Employs a Negative Temperature Coefficient (NTC) sensor to monitor skin temperature variances, useful for catching incoming sickness early. * Readiness Score: Looks at overnight Heart Rate Variability (HRV), sleep history, and recovery to tell you how physically prepared you are for the day. * Basic Activity Monitoring: Uses an on-board 3D accelerometer to trace steps, caloric burn, active time, and inactive stretches.
