WRIST-BASED HEART RATE
Optical heart rate5 technology gauges activity intensity as well as heart rate variability to calculate your stress level. It also tracks underwater without a heart rate strap.
PULSE OX SENSOR
For altitude acclimation, sleep monitoring or between Apnea activities on the surface, a Pulse Ox4 sensor uses light beams at your wrist to gauge how well your body is absorbing oxygen.
ALL DAY RESPIRATION
Track how you’re breathing throughout the day, during sleep and during breathwork and activities such as yoga.
ADVANCED SLEEP MONITORING
Get a full breakdown of your light, deep and REM sleep stages as well as Pulse Ox and respiration data. View it all on a dedicated widget that includes your sleep score and other insights.
RECOVERY TIME
After each workout, recovery time lets you know when you’ll be ready for another hard workout. It even accounts for training intensity and factors such as stress, daily activity and sleep.
TURN-BY-TURN NAVIGATION
Follow a route or course with help from turn-by-turn directions, which let you know ahead of time when the next turn is coming.
You deserve a watch that keeps up.
