Product Features

  • Music
    With up to 500 songs worth of music storage built right into your watch, Garmin is putting the "beat" in your daily mission to beat yesterday. It's easy to transfer music from your computer and then queue up your favorite playlist for easy listening through Bluetooth headphones. Now you really can leave your phone behind when you head out for a run, because the music that helps keep you moving is right there on your wrist.
  • Paying made easy
    Always on the run? Feel free to leave your phone and wallet behind. Forerunner 645 Music features Garmin Pay contactless payment solution, which lets you pay for purchases with your watch. Use it just about anywhere you can tap your card to pay. A bottle of water here, a bite to eat there - just pay, and keep on moving.
  • Tune up your training
    Garmin is making it easier to get the data you need to improve your form. Let Forerunner 645 Music measure crucial running metrics that you can use to analyze your performance. Biomechanical measurements, such as cadence, stride length, ground contact time and balance, vertical oscillation and vertical ratio, are the key to understanding your form so you can bring your best on race day. Also, take advantage of feature sets to help with cycling and even swim training. In the pool, Forerunner 645 Music will track your distance, pace, stroke count and more.
  • Monitor your performance
    Just how effective is your current training plan? Forerunner 645 Music will help you monitor your training and recovery so you can better prepare for a race or training cycle. Training status is a performance monitoring tool that automatically evaluates your recent exercise history and performance indicators to let you know if you're training productively, peaking or overreaching. The anaerobic training effect metric opens a window of insight to a critical dimension of training, telling you how your training is improving your ability to push the limits. You can even view your overall training load, which measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history.
  • Stay connected on the run
    Forerunner 645 Music makes it easy to run without leaving important smart features behind. Once paired with your compatible smartphone, you'll be able to receive and even respond to text messages and see social media updates, emails and more right on your wrist. Find your phone, access music controls, and let friends LiveTrack your runs.
  • Train your way
    Your routine is anything but routine. Forerunner 645 Music lets you change things up with ease, thanks to built-in activity profiles for running (indoor/outdoor), cycling (indoor/outdoor), swimming (pool), elliptical, paddle sports, strength training and many more.
  • Love the look
    Designed for runners, Forerunner 645 Music features a reliable five-button interface that lets you mark laps with a quick press. Feel free to take this watch outside in all kinds of weather. Not only is it safe for swimming and showering, its Garmin Chroma Display is easy to read - even in direct sunlight - and housed under chemically strengthened glass. When you want to change it up, swapping bands is fast and doesn't require tools. And with up to 7 days of battery life in smartwatch mode and 5 hours in GPS mode with music playback, Forerunner 645 Music is the running partner that can keep up with you.
