Garmin Forerunner 645 Music watch

This device is unlocked from any phone company (factory unlocked).

If your passion is to train, but really one of your priorities is to know how your performance is going, Forerunner 645 Music will help you know indicators that will improve your performance. When the device connects to a wireless WiFi network the music is synchronized.

This model, created by the renowned Garmin brand, has 5 buttons in physics to configure the activities. You can know the metrics that reflect your achievements during the exercise routine. Information about your careers is available for 24 hours. During that time, you can track all activities.

Those who have a medium-high performance, can enjoy this watch that stands out in several aspects: legibility of the screen and a large sphere on the wrist; however, the model is quite light. It can be configured for night races. The backlight is turned on for places or times of low light.

Music
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 favourite 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. If you’re a Deezer premium+ subscriber you can even sync your carefully-crafted playlists to your watch for more ad-free listening (coming soon).

Paying made easy
Always on the run? Feel free to leave your phone and wallet behind. Forerunner 645 Music features the Garmin Pay Ready contactless payment method1, 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 Music measure crucial running metrics2 that you can use to analyse 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. 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 Music will track your distance, pace, stroke count and more.

Training
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 new 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 new 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.
