The Forerunner 645 smartwatch is not only useful during running. In addition to advanced sports features, it is equipped with modern technology, a very durable construction and an elegant design. You can use it to your advantage during outdoor activities as well as in regular training and in everyday life. It is equipped with a classic control button, a nice colour display and an optical heart rate sensor. It is even ready for cashless payments, and integrates GPS and Glonass along with other technologies. It is perfectly waterproof.

Take Your Favourite Music with You

You can choose from several colour variants of this watch and a "music" version, which has a built-in flash memory for storing your own music and connects to the Deezer streaming service. Up to 500 songs can be stored in the 4GB memory. If you use or choose to use Deezer Premium+, you can download offline playlists from your computer directly to your watch.

Proven Controls with Modern Features

With most of its smartwatches, Garmin favours the use of classic buttons, and the Forerunner 645 Music Cerise is no exception. This system has the advantage of allowing demanding training in the rain, in winter or with swimming, situations where many modern touch controls fail. It is also worth mentioning an integrated barometric altimeter that can accurately measure not only the altitude, but also the speed of the climb.

What makes smartwatches clever are their multi-sport functions. The Forerunner 645 offers individual profiles for running outside or on the treadmill, cycling indoors or outdoors, swimming, elliptical training, paddle sports, strength training and a host of other sports. It is also equipped with WiFi, Bluetooth, ANT+ and NFC technology. You can dive with it without fear because it withstands water pressure up to a depth of 50m. This is not the most advanced Garmin model, so it is important to note that it is unable to measure your heartbeat while swimming, does not have a special feature for outdoor swimming or golf, and cannot be connected to cycling power metres.
