Garmin Forerunner 645 Music

Product description Garmin Forerunner 645 Music

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.

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.

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


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.

Great watch


Excellent watch and very comfortable 10/10

Awesome watch


This watch is just amazing, very happy with it.

Show well? bad service


The liveaisons are not good. Add some more hout for delivery. I put your packages on the lowest emergency. It's not a good service. I have not already mount my so I can not last if it's good.



Super satisfied It has everything that is missing. Being able to listen to music without a cell phone is great.



I love! It would be nice if they offered it with wireless headphones to listen to music. I miss the triathlon option.

Does it come in spanish?


I would like to know if the Garmin Forerunner 645 music comes with the possibility to configure the menus in Spanish. Spanish? Thank you

our experts answer

Yes, You can set up all the menus to spanish language when you configure the device. Regards.

Good watch


After a few days of use I can say that I have been successful with the purchase It provides a large number of data to monitor the activity, it allows me to connect Bluetooth headsets and the mobile phone In addition it is small Great product

Pure happiness for running


I replaced a Samsung Gear S2, which did not offer me effective coaching for the sport, by this watch. It's day and night ! After a year without physical activity due to health concerns, I wanted to get back to the sport while monitoring my activity and being coached daily on adapted programs. The Forerunner extended my wishes. The Garmin connect interface has a lot of information about what's going on (I only tested running and cycling for the moment). Connected functions are limited but perfectly sufficient (call alerts, can pick up from the watch, notifications, SMS, in short everything you really need). Only small complaint, the bracelet "cherry" is rather pink. I thought I could keep it (it is extremely comfortable) but it's really very feminine.

After 4 months of use


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


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


Excellent, small and very complete. Comfortable for all day, without giving up benefits.
