Garmin · Fitness Tracking
The Garmin CIRQA™ Smart Band in Captain Blue is a discreet, screenless wearable built for all-day comfort and all-night insight. With no display to distract, it focuses on capturing key health and fitness data around the clock, then presenting it clearly in the Garmin Connect™ app.
Designed for everyday wellness and training support, it delivers advanced sleep tracking, training-focused metrics, and automatic activity detection—plus up to 10 days of battery life. It pairs with iPhone® or Android™ and can use connected GPS through a paired smartphone for outdoor tracking. No subscription is required for core features, with an optional Garmin Connect+ plan available for premium tools.
Design
CIRQA™ Smart Band keeps tracking subtle with a screenless design and fabric ComfortFit bands. It’s made for continuous wear to capture data 24/7, and it supports quick release bands using 14 mm quick release pins with a 24 mm wide strap for easy changes when needed.
Battery
With up to 10 days of battery life, the band is built to keep up with busy weeks of wear, sleep and workouts between charges. Charging is handled through a Garmin proprietary plug charger, keeping the routine straightforward for daily use.
Connectivity
Health, sleep and fitness information syncs to the Garmin Connect™ app for review and trends, including the ability to confirm or edit automatically detected activities. An optional Garmin Connect+ plan adds premium features such as live activities, Garmin Coach training plans, nutrition tracking and Garmin Active Intelligence™ personalized insights powered by AI.
Health
CIRQA™ Smart Band provides advanced sleep tracking designed to make nightly data practical. It delivers a sleep score, tracks sleep stages and naps, and adds tools such as sleep coach and sleep alignment to help understand sleep consistency and circadian rhythm alignment. Metrics such as HRV status and skin temperature are also available to add context to recovery and overall wellness trends.
Training
For workouts and everyday movement, the band can track 80+ activities using the on-device button or through Garmin Connect, and it can automatically detect a variety of activities for later confirmation and editing in the app. Training-focused metrics include training readiness, training status, VO2 max, recovery time and workout benefit, helping show how the body is responding to recent effort and rest.
Connectivity
When connected to a compatible smartphone, CIRQA™ Smart Band can use the phone’s GPS for tracking during outdoor walks, rides and runs, with pace and distance data visible in Garmin Connect. It also supports Livetrack™ location sharing so friends and family can follow a location in real time, and it can broadcast heart rate to compatible Garmin devices using ANT+® or BLE.
