The Garmin Forerunner® 255 Music is not just a sleep optimizer or a fitness tracker; it's a lifestyle companion that fuses the best of both worlds. Designed to elevate your sleep quality while amplifying your training sessions with music and advanced analytics, this smartwatch is your ticket to a balanced, healthy life.
ADVANCED SLEEP MONITORING
Sleep is more than just "shutting down" for the night; it's a complex physiological process that the Forerunner 255 Music meticulously tracks. Leveraging wrist-based heart rate and movement data, the watch automatically detects and categorizes your sleep into light, deep, and REM stages.
- Sleep Score: Each night, you receive a sleep score between 0-100, summarizing your sleep quality based on sleep stages, duration, and heart rate variability. A higher score means better sleep, giving you a quick and effective way to gauge your rest.
- Sleep Insights: Personalized tips on your watch and in the Garmin Connect app guide you on how to improve your sleep. Whether it's adjusting your bedtime or modifying lifestyle factors, you get actionable advice tailored to your sleep patterns.
SLEEP BETTER WITH PULSE OX AND MORE
The Forerunner 255 Music brings additional layers of sleep health metrics, going beyond basic tracking to offer deep insights into your well-being.
- Pulse Ox Sleep Tracking: With all-day pulse oximeter tracking, this watch helps you monitor oxygen saturation levels and identify potential sleep conditions like sleep apnea.
- Sleep Mode and Do Not Disturb: Enter sleep mode to turn off notifications and adjust screen brightness for an uninterrupted sleep experience.
- Menstrual and Pregnancy Tracking: Through the Garmin Connect app, women can track how their monthly cycle or pregnancy is affecting their sleep.
STAY INFORMED WITH SLEEP WIDGETS AND HISTORY
Your sleep data should be easy to access and understand, and the Forerunner 255 Music ensures just that.
- Sleep Widget: A glanceable widget on the watch face shows your total sleep time and sleep score from the previous night.
- Sleep History in App: Dive deeper into your sleep trends with the Garmin Connect app, which compiles long-term statistics and graphs detailing your sleep stages, movement, and Pulse Ox levels.
MELODIC MOTIVATION FOR YOUR WORKOUTS
Step out for your daily run or hit the gym with your favorite tunes setting the pace. The Forerunner 255 Music features:
- Music Libraries and Streaming: Store up to 500 songs directly on the watch or access playlists from popular services like Spotify, Deezer, and Amazon Music.
- Hands-Free Music Control: Skip tracks, adjust the volume, and take control of your music experience directly from your wrist.
- Sound Quality: Enjoy crisp and clear audio quality, making your workouts more enjoyable and motivating.
ADVANCED FITNESS AND HEALTH METRICS
