Garmin Forerunner 645 overview

  • 1Description

Track your runs, gym workouts, outdoor recreational activities, bike rides, laps in the pool, and more with the Garmin Forerunner 645 Sport Watch. For added motivation Garmin has developed their own online community, simply download the Garmin Connect Mobile app and sync your data to see how you stack up against others within the social community.

Not only does the Garmin Forerunner 645 just track your activities, it provides deep analysis and insight so you can digest the data. Customizable data pages and activity profiles make it easy to display your data the way you want to see it. You can easily see your GPS speed and distance, your interval training and advanced workout statistics, your VO2 max., your training status, your aerobic and anaerobic training effects, the activity history on the watch, and much more.

In addition to intuitive analysis of your activities, the Garmin Forerunner 645 features a number of heart rate features including HR zones, HR alerts, HR calories, % HR max., % HRR, recovery time, auto max HR, and HR broadcast.

Did you leave your wallet at home while on that run? The Garmin Forerunner 645 has you covered with the Garmin Pay contactless payment solution, which allows you to just tap your watch and go. You can also receive text messages, social media updates, emails, and more right from your sport watch.

Paying Made Easy
The Forerunner 645 Sport Watch features the Garmin Pay contactless payment solution, which lets you pay for purchases with your watch. Use it just about anywhere you can tap your card to pay.
Tune up Your Training
Let the Forerunner 645 Sport Watch measure crucial running metrics that you can use to analyze your performance. Biomechanical measurements, such as cadence, stride length, ground contact time and balance, vertical oscillation and vertical ratio, are the key to understanding your form so you can bring your best on race day. These metrics are available with the addition of a compatible heart rate strap or the compact Running Dynamics Pod, which clips right onto your waistband. Also, take advantage of feature sets to help with cycling and even swim training. In the pool, Forerunner 645 will track your distance, pace, stroke count, and more.
Monitor Your Performance
The Forerunner 645 Sport Watch will help you monitor your training and recovery so you can better prepare for a race or training cycle. Training status is a performance monitoring tool that automatically evaluates your recent exercise history and performance indicators to let you know if you're training productively, peaking, or overreaching. The anaerobic training effect metric opens a window of insight to a critical dimension of training, telling you how your training is improving your ability to push the limits. You can even view your overall training load, which measures your exercise volume from the last 7 days and compares it to the optimal range for your fitness and recent training history.
More Ways to Customize
Check out the free to use Connect IQ store, where you can add personality to Forerunner 645 Sport Watch by downloading apps, widgets, watch faces, and more. New apps are added every day, so you can keep tabs on when your Uber is arriving, turn on your lights at home with the SmartThings app, and even use the AccuWeather MinuteCast app to find out when the rain will start. With the Face It watch face app, choose any image from your photo library, make some tweaks, and set it as your watch's face.
Stay Connected on the Run
The Forerunner 645 Sport Watch makes it easy to run without leaving important smart features behind. Once paired with your compatible smartphone, you'll be able to receive and even respond to text messages and see social media updates, emails, and more right on your wrist. Find your phone, access music controls, and let friends LiveTrack your runs.
Share and Compete
Syncing your activities to Garmin Connect is for more than just storing your data. Garmin Connect is a thriving online community where people on the go can connect and compete by joining challenges, encourage each other's successes, and even share their triumphs via social media. Garmin Connect is free and available on the web or on your smartphone with the Garmin Connect Mobile app.
Train Your Way
The Forerunner 645 Sport Watch lets you change things up with ease, thanks to built-in activity profiles for running (indoor/outdoor), cycling (indoor/outdoor), swimming (pool), elliptical, paddle sports, strength training, and many more. Create your own custom workouts, and download for free from our Garmin Connect online fitness community. Then review your past efforts on the app, or share them with family and friends for added motivation.
Love the Look
Designed for runners, the Forerunner 645 Sport Watch features a reliable five-button interface that lets you mark laps with a quick press. Feel free to take this watch outside in all kinds of weather. Not only is it safe for swimming and showering, its Garmin Chroma Display is easy to read - even in direct sunlight - and housed under chemically strengthened glass. When you want to change it up, swapping bands is fast and doesn't require tools. And with up to 7 days of battery life in smartwatch mode and 14 hours in GPS mode, the Forerunner 645 is the running partner that can keep up with you.

    Garmin Forerunner 645 reviews

    Forerunner 645 Sport Watch (Black) is rated 4.5 out of 5 by 2.
    Rated 4 out of 5 by from Made for Sports I will review this in portuguese in order to help brazillians. O relgio vai alm das espectativas, no um Smart Watch, um Relgio Garmin para esportes, que de quebra tem conexo com o celular com algumas funes muito boas! Preciso tanto no contador de passadas quanto na medida de pulso. Conectado com o Garmin Connect via WiFi e Bluetooth o que realmente o traz a frente dos outros. Se conecta com todos os perifricos garmin. Antes eu tinha um Forerunner 910XT, que s atualizava por conector ANT+, e no tinha podometro e pulso imbutidos. Mesmo assim se quiser consigo utilizar o podometro e a fita cardiaca do 910XT que comprei h 8 anos atrs. Fantastico relgio!

    Rated 5 out of 5 by from Really Happy So far! This watch has totally met and exceeded my expectations.� I have the non-music version - sounds like most of the issues/bad reviews are on the music version. Coming from a Samsung smartwatch and activity tracker, battery life is great.� Activity tracking/steps seem spot on, GPS is very accurate, Wrist HR accuracy is better than any other device I have had, it's far from exact but it's close enough that I feel comfortable using it as a guide. I have also used with strap and they were pretty close. Watch/strap is very comfortable to wear.� Not crazy about the silver bezel - seems like it could/will scratch up over time.� I debated over the VS3 instead to save the money and not sure I would like the buttons over the touch screen - very glad I went with the non-touch screen - also has a very short learning curve to navigate with the buttons.
