Would you rather not wear a heart rate strap? Garmin Forerunner 235 is the first Garmin sports watch with heart rate measurement on the wrist. Simply put on your watch, put on your running shoes, and you're ready to go. Read your heart rate and heart rate zone while you're running, so you can adjust your effort to the right level. The watch offers a race time forecast and recovery time. Bringing out your smartphone to control your music is a thing of the past, since you can simply control music via the buttons of the Forerunner 235. You don't have to worry about missing your messages or calls, either. These are displayed on your watch.
