Garmin · Fitness Tracking
The Garmin CIRQA™ Smart Band in Captain Blue is a discreet, screenless wearable built for people who want advanced tracking without constant on-wrist distractions. Its comfortable fabric band is designed for all-day and all-night wear while supporting a wide range of health, sleep and training features.
It delivers 24/7 monitoring plus fitness tracking with no subscription required, and it works with the Garmin Connect™ app for deeper insights and activity review. With up to 10 days of battery life and Swim, 5 ATM water rating, it fits daily routines from workouts to recovery-focused nights—then lets users review their data later in the app.
Display
CIRQA™ Smart Band keeps tracking in the background with a screenless design made for comfortable, continuous wear. Health and fitness data can be reviewed in the Garmin Connect™ app, helping users stay focused during the day while still capturing key metrics around the clock.
Battery
With up to 10 days of battery life, CIRQA™ Smart Band is built to keep up through training days, rest days and nights of sleep tracking with fewer interruptions for charging. It uses a Garmin proprietary plug charger when it’s time to power back up.
Connectivity
CIRQA™ Smart Band pairs with the Garmin Connect™ app for viewing health and fitness trends and for confirming or editing automatically detected activities. For those who choose it, an optional Garmin Connect+ plan adds access to premium features in the app.
Health
CIRQA™ Smart Band provides extensive wellness tracking throughout the day and night, including Body Battery™ energy monitoring, stress tracking, wrist-based heart rate with high and low alerts, and Pulse Ox blood oxygen saturation monitoring (optionally all-day and in sleep). It also supports women’s health tracking, including past ovulation estimates, and lifestyle logging in Garmin Connect to review how habits can relate to personal wellness trends over time.
Training
For recovery-focused users, CIRQA™ Smart Band delivers advanced sleep tracking with a sleep score and sleep stage breakdown, plus tools like sleep coach, sleep alignment and nap detection. It also tracks HRV status and skin temperature to help users better understand nightly patterns. A smart wake alarm gently vibrates to wake the wearer at the right time, supporting a more refreshed start to the day.
Connectivity
CIRQA™ Smart Band supports 80+ activities started from the on-device button or through Garmin Connect, and it can automatically detect a variety of activities that can be confirmed or edited in the app. During outdoor walks, rides and runs, it can track location when connected to a smartphone’s GPS, showing distance and pace data in real time in Garmin Connect. It can also broadcast heart rate to compatible Garmin devices using ANT+® or BLE.
