Oura Smart Ring Men's Size 12

Comfortably wear Oura Ring all day and night to collect deeply personal health metrics and insights. Your finger provides the most accurate reading of over 20 biometrics that directly impact how you feel. This wass a gift for my husband, but only likes his rubber rings. It has never been worn and comes with box, charger cord plus original packaging and pamphlets and an extra car charger. I do not know what generation this is because he never downloaded the app. Box date is 2019.
