Garmin Forerunner 645 Music review

The following is my personal and unqualified opinion about the Garmin Forerunner 645 Music. There has been no product placement or anything. The watch was purchased with my own hard-earned dollars. But I would also like to emphasize right away that inside me there is a little hidden Garmin fan and waves the flag. I am equally satisfied with their products, with their way of managing customer service, complaints, etc.

The test was conducted with the Garmin Forerunner 645 Music – the extended model where it is possible to store music on the watch. As previously mentioned, the test took place over more than half a year. And during this period I have used the watch primarily. That is, it is only the watch I have used for sports and everyday life. So the data basis is in order.

NOTE: Find the shoe through iloebesko andsave 1.600 crowns. Regular price: 3,799 kroner, so there are great deals right now. Find it at one of our partners.

10 good reasons to choose the Forerunner 645 from Garmin

Here I have tried to give you my best guess as to which 10 features should be your incentive to choose to buy the Garmin Forerunner 645 (Music).

Music in the clock:
Great feeling not having to rely on running with your phone to listen to music.

Dual function:
The Garmin Forerunner 645 Music can be used for both everyday use and sports.

Wrist pulse:
If, like you, you feel claustrophobic wearing a heart rate monitor, then the wrist pulse is really nice.

Sleep monitoring:
Sleep is underrated when it comes to improving or peaking performance. A small but very useful feature.

Refund recommendation:
The watch knows your day, your routines, your stress level and not least your training. Based on this, it comes up with optimal recovery time. And it is important to recover correctly. That is where you get better and stronger.

Garmin Connect:
I know all Garmin watches have it, but that’s why it’s still a feature that makes you choose Garmin over, for example, Polar or Suunto.

Activity indicator:
There’s someone who keeps an eye on your daily activity level. A motivator like no other.

Training effect (Aerobic or Anaerobic):
The fact that the watch keeps track of your training effect is just a cool thing. Whether you want to nerd out about what the terms mean and how to achieve the best training is entirely up to you.

Battery life:
I think the Garmin Forerunner has a relatively and acceptably long battery life. If nothing else, it charges insanely fast.

My 5 favorite features of the Forerunner 645

The watch has a lot of functions. Many, many more than it would make sense to write about here. But if you still can’t control yourself, here are the full list of features in Forerunner 645 Music

This section is about which features I personally think are the coolest, and probably also the features in the Garmin Forerunner 645 that I use the most. I think you’ll be surprised how banal features a “running nerd” like me appreciates in such a watch. But let’s see. It’s hard to list. Because there are things that you basically expect such a watch to be able to do. It’s basic for such a watch that it can measure speed, distance and all that. So there are features beyond that.

2 clicks and you’re ready to go:
I love that I can just press the same button twice and I’m ready and able to start measuring my activity. Of course, this function applies to the activity you have set as a favorite.

Dual function:
That’s actually why I replaced my Garmin Forerunner 735xt. I wanted to move away from this sporty look and into a more stylish design. The Forerunner 645 solves that perfectly.

Sleep monitoring:
Many say it’s a sales pitch and all sorts of other things. But I really use my sleep monitoring a lot. Especially before competitions or during periods when I need to improve. Sleep is underestimated in relation to peak performance. I don’t really care about light and heavy sleep, but primarily use the length of my sleep.

Custom training programs (Garmin Connect):
Part of Garmin Connect. Personal training programs that can be coded to act almost however you want. Use this feature a lot. Especially for setting up my interval training programs.

Music in the clock:
Even though it might not be the best idea to run without your phone (from a safety perspective), I still love the idea of ​​being able to run without having to rely on a phone for music. Easy to set up for Spotify, for example. The only downside is that it requires a paid subscription to Spotify.

Notifications (Bonus 1):
Personal settings for notifications from individual apps. That I decide which notifications I receive. That’s one thing. The other thing is that it’s just a nice feature. When you have a job, for example, where you can’t and aren’t allowed to be near your own phone all the time, you have the opportunity to follow along a bit anyway, and possibly be aware of suddenly arising crisis situations.

Fast charging (Bonus 2):
I was just incredibly surprised at how quickly the watch charges. It has an okay and acceptable battery life. But if you use GPS, it does suck up power. But it doesn’t matter that much when the watch is ready again after a short time.

Sorry I couldn’t stick to 5. Sorry!

Advantages and disadvantages of the watch

Below I have listed some brief advantages and disadvantages of the watch.

I use my Forerunner 645 for many activities

Although my favorite activity is running, and I’m incredibly happy to be able to start in 2 clicks. Then I use my Garmin Forerunner 645 for both skiing, circuit training, walking and crossfit training. Their skiing activity in particular seems to me to have been significantly upgraded and better since the last time I tried to use it on a Garmin heart rate monitor. Both my circuit training and my crossfit training are based on self-built training programs, which are all built in Garmin Connect and then transferred to the watch.

Garmin Forerunner 645 has a little brother

If you only take the fact that you can play music directly on the watch as a starting point. Then the Forerunner 645 has a little brother or sister if you will. It’s called the Garmin Forerunner 245 Music. The things you don’t get in the Forerunner 245 vs. 645 are, among other things, the metal watch face, the stress test module and Strava Live segments. If you can live with the sporty look, then the other “missing” is basically something I could easily live without. Because I would never use it.

I love Garmin Connect

It’s not unique to the watch, but that’s why it still helps to strengthen the whole. Garmin’s platform for activities, apps, settings, etc. I think it’s perfect. Easy to navigate, and easy to figure out. You can actually make your own training with very few clicks and transfer it to the watch. The Garmin Connect app is always up to date, and I use it a lot in terms of checking sleep rhythm, performance, and the like.

The Forerunner 645 is in the middle

When you look at Garmin’s own website, and their overview of Forerunner running watches. The Forerunner 645 is placed right in the middle of it all. But it is certainly not because it is a “middle watch” or worse yet a mediocre watch. At least that is not the feeling I have after using the watch for almost half a year. The watch has not yet disappointed me to such an extent that I have almost been in the direction of regretting my purchase. Quite the opposite.

At the time of writing, Garmin has 5 basic models when it comes to Forerunner running watches. There are:

Garmin Forerunner 45
Garmin Forerunner 245
Garmin Forerunner 645
Garmin Forerunner 735xt
Garmin Forerunner 945

From the above basic models in watches, some variants emerge. Among others, the watch that we have used in this test Garmin Forerunner 645 MUSIC. This means that there is both a Forerunner 645 with and without music. The Garmin Forerunner 45 is available in a regular and an S model. The S model is slightly smaller. And in line with the Forerunner 645, the Garmin Forerunner 245 is also available in a MUSIC version. So instead of 5 basic models, there are actually 8 different Garmin Forerunner running watches right now.

Does the Forerunner 645 from Garmin have too many features?

One of my pet peeves when it comes to this kind of equipment is that you have to learn to limit yourself. But you just have to give Garmin credit for being so crazy good at putting so many features into their watches. So it doesn’t even seem like a limitation. But what I want to say with that sentence. Is that there is absolutely no reason to choose a watch with more features than you need or use. Because experience tells me that you will run out of them. And the superfluous features can be more de-motivating than motivating.

Personally, I fell into that trap myself. Or if I have to defend myself a little, I didn’t anyway. But the Garmin Forerunner 645 has WAY more features than I’ll ever use. But one of my requirements for the new watch I was going to get was that it should be a sports watch and an everyday watch. I wanted to get away from this “sports look” a bit. And in that light, I had 2 choices when I bought it. Garmin Forerunner 645 Music or Forerunner 945. And since the Garmin Forerunner 945 has more features, I actually chose the watch with the least features. Wasn’t that a good excuse? ;-) Could it also be that you’re just a gadget nerd!?

I probably shouldn’t say that another requirement was music in the watch! Because then I could have gone the other way and chosen the Forerunner 245. You just read further up that the FR245 is the little brother of the FR645. But that wasn’t fun.

Alternatives to the Forerunner 645

A direct alternative to the Garmin Forerunner 645, it probably depends entirely on what you value. Because if it’s the music integration, then the alternative is obvious. Then you should look for the Garmin Forerunner 245 Music. It’s the only alternative in the Forerunner series from Garmin. But if it’s one of the other functions, then there are actually plenty of alternatives. If it’s the more advanced functions, you should probably look in the same cluster that I think the Forerunner 645 belongs to. Then you should look for watches like the Forerunner 735xt or Forerunner 945.

Garmin Forerunner 645 offer

With a background in the sports industry, I know a lot about the benefits of electronic products in connection with sports and running. Now I’m not in that industry anymore, so I’m happy with all the deals on Garmin watches I can find. But I can reveal that in the old days, selling these could easily be a zero-sum business. But you don’t have to do many Google searches or other posts to conclude that there is almost always a price war on such products. There are 2 huge advantages to this. One is the good price. The other is that we have collected the best prices for you here. It doesn’t get any easier:
