Garmin Forerunner 645/645

  1. Design
  2. The Forerunner 645 is housed in a decent circular shape made of some of the most durable materials. It has a stainless steel bezel that does make it look classic and decent enough to grace your wrist even for high profile occasions.

    The sunlight visible transflective Memory-in-pixel display is not the most interactive display, but it’s certainly a lot easier to view outdoors. Something, those who engage in outdoor sport will appreciate especially when in the heat of the sun.

    The sizes are moderate too which means this is one watch that will be a nice fit for a lot of people, while the watch face is customizable. Just in case you don’t like it, you can simple download one of your choice from the Garmin connect store where they have some really nice watch faces.

  3. Long Battery Life
  4. One nice attribute of the Forerunner 645 is the quite impressive battery life that will see you go longer on a single charge with this device. On smartwatch mode, it’s about 4-7 days long battery life while with GPS active, you should expect about 10 hours of battery life.

    No doubt impressive, and a great deal for runners who engage in longer durational activities.

  5. Waterproof Rating
  6. The Forerunner 645 is rated 5ATM which means it water-resistant up to 50 meters. So it’s swim-proof and with the swim-tracking features such as stroke count, pace, calories and swim efficiency (SWOLF), it’s a great choice for swimmers who like to monitor their performance while swimming.

  7. Activity/Fitness Tracking
  8. As a fitness smartwatch, the Forerunner 645 comes with all the standard sensors you’d expect to find in a fitness tracker.

    It includes the heart rate monitor, inbuilt GPS with support for the multi-satellite system, altimeter, and accelerometer which accounts for the 645 huge fitness tracking features and support for automatic tracking of a number of sport modes.

  9. Media
  10. The Forerunner 645 and 645 Music are the two models released under the 645 series. While the standard 645 model lacks onboard music storage, the 645 Music has enough onboard storage to contain over 500 music tracks.

    You can download and as well stream your favorite tracks from Spotify to the 645 which you can listen to on the go via a Bluetooth enabled earbud.

    This is one nice feature that comes handy in helping stay remain on focus, avoiding unnecessary distractions.

  11. Notifications

With Wi-Fi and Bluetooth available, the Forerunner 645 is able to keep you connected to all that matters to you. It’s compatible with both Android and iOS devices which when successfully connected to a compatible device, syncs emails, incoming calls and other notifications alerts from both third-party and native applications to the watch.

The Forerunner 645 also features an NFC that supports Garmin Pay which lets you make payment directly from the watch.

  • A decent looking smartwatch.
  • It is swim-proof.
  • A great choice for comprehensive activity tracking.
  • NFC and music storage available.
  • Impressive battery life.
  • Lightweight design.
