Regardless of your fitness goals, the epix premium active smartwatch has what you need to help you get there. For altitude acclimation or sleep monitoring, a Pulse Ox sensor2 uses light beams at your wrist to estimate how well your body is absorbing oxygen. The watch constantly samples your heart rate and will alert you if it stays too high or too low while you’re at rest. It also helps gauge how hard you work during activities — even while swimming. See how you’re breathing throughout the day, during sleep and during breathwork and yoga activities. Log a 2-minute session to record key stats, including heart rate, heart rate variability, Pulse Ox2, respiration and stress. Then generate a report with those stats to share via the Garmin Connect™ app on your compatible smartphone. Heart rate variability is used to calculate your stress level score, so you can see if you’re having a calm, balanced or stressful day. Get a full breakdown of your light, deep and REM sleep stages. View it all on a dedicated widget that includes your sleep score and insights.
