The Forerunner series of wearable gadgets from the American brand Garmin is addressed, as the name implies, to adherents of running sports disciplines. However, the watch handles with other types of activity just as well.

Running activities

While running, the “smart” gadget on the wrist registers a lot of parameters. At the head of the list are the classic indicators of the number of steps taken, distance covered and calories burned. At the same time, the watch collects data on the distribution of foot-to-ground contact time, vertical oscillation, cadence, measures stride length and predicts the estimated finish time. The measured indicators are transferred to the Garmin Connect mobile application, where they can be easily interpreted.

Sports functionality

Running is the main, but by no means the only element of sports watches. They also collect information about the user's activity when cycling, during cardio training or during swimming lessons(the gadget can withstand immersion under water to a depth of 50 m). The extended functionality of the model includes round-the-clock heart rate monitoring for a rational distribution of the level of load and rest. In addition, the Garmin Forerunner 645 did not do without the support of GPS navigation.

Contactless payments

As usual for self-respecting smartwatches, the model can duplicate notifications from a smartphone, displaying them on a 1.2-inch transflective screen with a resolution of 240x240 pixels. Moreover, its assets include an NFC chip and support for the Garmin Pay payment service. Taking advantage of all its charms is as easy as shelling pears: we link a bank card in the mobile application and, at the stage of paying for goods in the supermarket, we simply attach the watch with the PIN code entered in advance to the terminal.

battery life

The "smart" gadget demonstrates excellent battery life — up to 7 days with GPS navigation disabled. With the active work of the geopositioning module with a polling frequency of about 1 s, the watch will die for a long time after 5 hours of active training. The model also has a more advanced relative in the face of the Garmin Forerunner 645 Music — smartwatches similar in functionality, but with a built-in audio player and memory for a good five hundred songs.

Additional features smart watch Garmin Forerunner 645:
  • Virtual partner
  • Tracking movement in real time (Live Tracking)
  • Recovery Recommendations
  • Determination of the maximum volume of inhaled oxygen
Model differences:
  • Forerunner 645 Music - built-in audio player
  • Forerunner 645 - no built-in audio player
