Differences (Forerunner 645 Music vs Vivoactive 3)


Music


Music is undoubtedly the biggest and latest innovation in Garmin watches. This is unique to Forerunner 645 Music model.

Unlike this one, the simple version does not have this service. Forerunner 645 Music can store up to 500 songs making it possible for you to leave your phone at home.

It has collaborated with iHeartRadio to sync playlist you had already downloaded offline using the Garmin Connect IQ application.

In the watch, open Garmin Connect, search for music apps or iHeartRadio app, and install it on your phone.

You can also load up your smartwatch with MP3 and AAC files. Just install Garmin Express client app on your desktop and choose the songs to transfer.

You can also pair it with Bluetooth headphones to listen to the songs during a run.

Unfortunately, this feature is not available in Vivoactive 3.


Advanced Running Dynamics


Avid runners or athletes look for new, advanced running dynamics to monitor their workout sessions on different levels.

Forerunner 645 Music is compatible with HRM and Running Dynamics Pod to give you advanced running stats. It includes ground contact time, vertical oscillations, stride length, etc.

These metrics are very useful for professional athletes, but might not be important for others.Some fin cadence as an important feature than the stride length. Therefore,everyone depends on the customer. 

Vivoactive 3 does not have such advanced running dynamics.


Battery


The battery life in Forerunner 645 Music is pretty good. It can be used for a week straight after one time charge in smartwatch mode and for 5 hours in GPS mode with music.

If you use it to track multiple workouts with the GPS on and listen to music simultaneously, it can stay up for 4 hours which is great.

The battery backup of Vivoactive does not vary a lot. It can go about 3 days with GPS and heart rate sensor activated. It implies that you can easily wear the watch overnight.


Design


Vivoactive 3 has a combination of touch-screen controls and a button on the side. To view a smartphone notification, you need to tap the watch face.

But to pause a workout session, press the side button. It has a round watch face giving it an analog watch look.

There are new watch faces available in the Garmin Connect app. You need to download them. If you are not using the watch, it dims the display to conserve battery.

Forerunner 645 music is sporty and functional with 5 buttons on the sides. All the buttons have labels to make it easier for users to know their respective functions. It is made up of stainless steel bezel. There are button display lights on the sides.


Price


Garmin Forerunner 645 is much more expensive than Vivoactive 3 due to the new music feature and better battery backup. Both the products are available on Amazon (Click here to find out the price for Garmin Forerunner 645 & Vivoactive 3 ).


Golf Support


Golf support feature is available in Vivoactive 3. This is another difference between the two watches. If you are an avid golfer, then Forerunner 645 is not the ideal choice for you as it cannot measure your activity and thus the stats related to it.
