Product information

Pros and cons

According to our smartwatch expert
  • Thanks to the included Garmin heart rate chest strap, your heart rate readings are extra accurate.
  • The watch displays heart rate zones during training, so you can train focused on endurance, for example.
  • With GPS and GLONASS, the watch determines your location, speed, and route more accurately than with comparable watches.
  • The watch doesn't support music storage, so you have to take your phone for music while your exercise.
  • The separate heart rate monitor is only splash proof, so you can't use it when you swim.

Product description

Monitor your heart rate extra accurately with the Garmin Forerunner 45S Black + Garmin HRM-DUAL Heart Rate Monitor Chest Strap Black bundle. You connect the HRM-DUAL heart rate monitor to your Forerunner smartwatch via ANT+. The built-in heart rate sensor of your smartwatch automatically monitors your heart rate throughout the entire day. In addition, you can stay up to date about your calorie burn, the number of steps you take, and your sleep. The watch case is 1.56 inches, so it's also suitable for a smaller wrist. No one to work out with? With the virtual partner on your watch, you'll always have someone to compete with. Connect the smartwatch to your smartphone and receive notifications from Whatsapp, Facebook, and Instagram on your wrist. The chest strap of the heart rate monitor is easily adjustable to a size between 63.5 and 132cm.

Note: an adapter isn't included. Do you want to charge the watch via a socket? Use the adapter of your phone charger or order a separate adapter.

Nice watch for targeted training

  • Possibility to create extensive workouts yourself
  • Easy to operate buttons while running
  • Quick sync with phone

Good watch to record your run. If you follow a schedule you can set it as a workout, then you will receive feedback while walking if your pace/heart rate/cadence value is higher or lower than your set goal. Afterwards, the route and data are clearly visible in the Garmin Connect app and, if necessary, linked also in strava. I believe you can also download ready-made Garmin workouts.

Nice watch for a nice price with many running functions.

  • Easy in use
  • Nice design, not that big (so also suitable for smaller wrists)
  • Suitable for all kinds of workouts
  • Connecting to GPS takes quite a while. Hopefully there will be a good update from Garmin for that

Nice watch for a nice price with many running functions. You can set up all kinds of training programs via the Garmin app, but also, for example, via TrainingPeaks (via Garmin app). Watch charges quickly and battery lasts long enough. The watch has a beautiful design, so you can also wear it as a "normal" watch.

Good wearing comfort and easy to use.

  • Suitable for small wrists
  • Easy to use
  • Handy app
  • Do not connect to phone.

Very nice watch so far. Very easy to use with the Garmin Connect App. I have a fairly small wrist, so watches often feel large and bulky. Definitely not this one! Recommended.
