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.

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.
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.

Lightweight, compact and versatile
Adelaide trabuco - 08/07/2019
This watch is super lightweight. Although not tactile it is easy to use. It is versatile because there is a wide range of bracelets on the market for all occasions. As for the training reports, in my opinion, they are complete and useful.
André - 14/04/2019
This watch is just amazing, very happy with it.
Show well? bad service
Dergent wouter - 22/02/2019

Sascha von gostomski - 07/02/2019

After 4 months of use
Salvador - 04/09/2018
After 4 months and the last update 3.7, I can not be happier. I wear it 24 hours and I do not notice it. I have used it in swimming, hiking and running. In the latest update they have added the manual calibration of the barometric altimeter. Everything works very well, to be a tiny watch. The reports, the metrics, training ... fundamental to evolve and keep track of progress even if you're amateur. The battery is charged, I charge it every 5 days with 2 outputs of 40/50 min running with music and 1 exit walk of 3 h without music and 1 h of elliptical.
Very good purchase
Sylvain - 16/08/2018
Certainly a better watch of the moment, very light beautiful and powerful. Delivery service at the top. Thanks to Runnerinn
Enchanted with product and service
Salvador - 19/05/2018
