SAMSUNG Galaxy Watch 7 (44mm) AI Smartwatch with 1.5" AMOLED Display, Wear OS 5, Wi-Fi, Bluetooth, Heart Rate & Sleep Apnea Monitoring, GPS Fitness Tracker - International Model L310 (Fast Charger Included, Green) | Perfect for Workouts, Running, Sleep Tracking & Daily Activity Monitoring

I had a galaxy watch years ago and forsook it for a fit bit charge (opting for smaller) but became frustrated with it's inaccuracy, especially wrt heart. Finally went back to Galaxy Watch 7 and loving Samsung health. Usually have to recharge every other day, usually during morning after I exercise. Love the sleep and snori g tracking as well as the ECG and sleep apnea function. I have a Samsung phone and am loving them both. Samsung for life!
