Running is more than just exercise — it's a performance. And Forerunner 645 Music has the tools to help you put on an outstanding show every time you lace up your shoes. It features on-device music storage — so you can run with your favorite tunes — and contactless payments that let you buy what you need without missing a beat. With all those features plus advanced running dynamics and performance monitoring tools, this GPS running watch is the instrument you need to refine the performance.

With up to 500 songs worth of music storage built right into your watch, we're 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. You can even sync your carefully crafted playlists from select music streaming services¹ to your watch for more ad-free listening. 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 features Garmin Pay contactless payment solution¹, 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
We're making it easier to get the data you need to improve your form. Let Forerunner 645 measure crucial running metrics that you can use to analyze your performance. Biomechanical measurements², 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. These metrics are available with the addition of a compatible heart rate strap or the compact Running Dynamics Pod, which clips right onto your waistband. Also, take advantage of feature sets to help with cycling and even swim training. In the pool, Forerunner 645 will track your distance, pace, stroke count and more.

Monitor Your Performance
Just how effective is your current training plan? Forerunner 645 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.

More Ways to Customize

New apps are added every day, so you can keep tabs on when your Uber is arriving, turn on your lights at home with the SmartThings app, and even use the AccuWeather MinuteCast app to find out when the rain will start. With the Face It watch face app, choose any image from your photo library, make some tweaks, and set it as your watch's face.

Stay Connected on the Run
Forerunner 645 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 respond6 to text messages and see social media updates, emails and more right on your wrist.

  • User friendly and perfect size for a lady’s wrist.
  • 日本語さえ出てくれれば。。。

  • 日本で使ってます。 サイコンに心拍数を飛ばすために購入しました。その点は満足です。 あまり期待して無かったんですが、ゴルフでもコースを無料でダウンロードできるなど意外に使えます。ただ専用機とヤーデージが違ったりしてたので、どの程度精度が出るかは判断つきません。 一方で、電話やLINEなどのメッセージが届いたときにスマートウォッチに表示される機能はサイクリング時以外にも使えると思い期待していましたが、これは文字化けしてしまい全く役に立ちません。先程のゴルフ機能でも、ダウンロードしたコース名が読めません。 これはガーミンのローカライズ戦略のようですが、グローバル化された現代にはそぐわない戦略ですね。残念でなりません。インターネット普及前ならまだしも。主目的は果たせたものの、他の人におすすめできるかという観点では低評価とならざるを得ません。改善を願います。
