Paying Made Easy
Always on the run? Feel free to leave your phone and wallet behind. Forerunner 645 Music features 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. A bottle of water here, a bite to eat there — just pay, and keep on moving.
Tune up Your Training
We’re making it easier to get the data you need to improve your form. Let Forerunner 645 Music measure crucial running metrics that you can use to analyse 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
Just how effective is your current training plan? Forerunner 645 Music 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 Customise
Cheque out the Connect IQ store, where you can add personality to Forerunner 645 Music by downloading apps, widgets, watch faces and more. It’s easy and — even better — it’s free. 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
Forerunner 645 Music 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. Syncing your activities to Garmin Connect is for more than just storing your data.

My desired requirements:
More activity tracker than a smartwatch. Good battery life. Reasonably accurate activity tracking (hopefully it will improve with more calibration). Lap swimming - more importantly, I wanted a watch that would be able to guide me through a workout.
Nice shape and size
I like the fact that it is not a touchscreen
Excellent swim training mode (it buzzes and dings on the last length of an interval/set, so you don't necessarily need to keep track)
Great battery life (so far)
Music storage (I have not used this yet)
Garmin Pay is not functioning
While I do not like touchscreens, getting used to the buttons takes a little time
Not the cheapest watch out there
Other watches tried:
Garmin Fenix 5 with sapphire glass
PROS - amazing features. Bomber construction. Great design. Accurate tracking. Swim features were great. A multitude of pre-installed activities.
CONS - display a little dark because of sapphire glass. Limited app selection on Garmin Connect. Even though this is a lot smaller than the predecessors, I still think it is a pretty hefty watch. The last nail in the coffin for this incredible watch was close to 50% price difference for a watch that didn't hit everything I wanted.
Samsung Gear Sport 2
PROS - reasonable price point. Great display. Samsung Pay worked well. Pretty nice design. Good variety of apps available. Can store music on board.
CONS - More smartwatch than a fitness tracker. Fitness tracking was inaccurate. Battery life was not great. Better than an Apple Watch, but not bad compared to the Fenix 5. Only had swim tracking, not workout guidance and tracking is inaccurate.
Samsung Gear Fit 2 Pro
PROS - excellent price point. Display nice and sharp. Battery life was pretty good.
CONS - Inaccurate activity tracking - it was .5 miles off over 2-mile run. No Samsung Pay. Not wild about the shape or aesthetic. Only had swim tracking, not workout guidance and the tracking was inaccurate.
Garmin Vivoactive 3 HR
PROS - Decent pricing for what you get. Nice size and shape. A good set of options.
CONS - Lacking swim workout function. Battery life could be better. Touchscreen overly sensitive.
I struggled with the extra price between the 645 music and the Vivosmart 3, really just for the music. Even a 235 probably has everything I need from a training perspective. But in the end I caved in to FOMO, and bought the 645, for the music and for the lack of touch screen, which some reviewers got me worried about being overly sensitive on the VS 3.
The music is the best nice to have, I have a big phone so I am not going to haul that around on my training run, and my little Clip Sports MP3 player was always not to be found or out of battery at the most annoying moments. Because I don't always run with music, a last minute decision (music or not) is always easier on the 645.
The music does cut out more often than the phone or my Clip, even though I have approved headphones and use it on the correct side. But not enough to be annoying or unusable. Also as some reviewers have pointed out it is very finicky about which which headphones it will pair with: yes to my JBL Reflect Minis,; no to my Senso ActiveBuds 250. I also, just out of curiosity, tried to pair it with a few Bluetooth speakers, and it was hit and miss there also (this is not a use case I worry about though)
Battery life is spot on from Garmin estimates, as a percentage drop here are some times I have measured:
Activity with music and GPS at the same time: about 20% battery level drop per hour
Activity with just GPS: about 10%
Regular use no GPS, Music or WiFi: about 17% per day
Regular use with no HRM, Music, GPS or Wifi: about 8% per day. (This is the way I use it, the green HRM light bothers me at night)
I have yet to get caught without enough battery for a run, and that is because so far the device charges up to 100% in the little time it takes me to down load a new play list. I does recharge very fast.
The Garmin pay works just fine, I tested it for yucks and suitably impressed the cashier at CVS. But I can't see ever using it, as I don't normally buy anything on my runs.
So overall I am please with my purchase, I knocked off one star in the review only because I still get a knot in my stomach when I think of the price I paid. If I am still using this watch regularly 2 years from now, I will give the 645 the final star.
(Running software version 3.10 at the time of this review)
