Design & Physical Attributes: Garmin Forerunner 45 Plus vs Forerunner 45

In essence, both Forerunner 45 and Forerunner 45 Plus are pretty lightweight. However, the smallest version of the former weighs around 32g, while the latter’s weight is 30g. So, in a way, it is only a minor change that the new comes with. 

Secondly, the Forerunner 45 GPS running watch can fit around the wrists of 125-185mm in the perimeter. However, the change in this aspect is quite prominent in the recent release as well. The brand new 45 Plus is capable of fitting wrists of 129-197mm in circumference.

In terms of the overall design, both of these products do feature a rather minimalistic approach. Each of them has a circular-shaped dial, which looks pretty good, to say the least. Moreover, the details written inside are pretty clear, as well.

Furthermore, the display size and resolution of these two models, too, seem to have some similarities. For example, the watches come with a 1.04-inch display, which has a resolution of 208×208 pixels. 

However, the display type of each of these products is different. For instance, the Forerunner 45 comes with a simple LCD screen. Conversely, on the other hand, 45 Plus features an LCD-screen with transflective MIP technology. 

Then again, the glass of the watches is equally durable. Each of those has been manufactured with high-end materials and reinforced with various types of harmless chemicals. Also, both of them feature silicone-made straps. 

Winner: Forerunner 45 Plus (Ever-so-slightly)

Usability and Exclusive Features: Garmin Forerunner 45 and Forerunner 45 Plus

Garmin Forerunner 45 Plus

The Forerunner series of Garmin is known for being very user-friendly and easy-to-use. Hence, as expected, each of these two products offers the same facilities as well. Both of them have a decent display with everything written on it clearly. 

The buttons of the models are pretty ergonomic and durable as well. So, you can navigate through them quite comfortably. So, in a way, there is no winner among Forerunner 45 vs Forerunner 45 Plus in these two aspects.

Let’s move onto features now. The Garmin Forerunner 45 comes with several personalized training schemes, which can be ideal for the beginner. The same is available in 45 Plus as well. However, you can add a lot more plans here than you could in the Forerunner 45. 

Both of the watches mainly focus on running (you have probably already guessed from the name). However, each of them does have a lot of other activities recorded in it as well. For example, you can get around 12 different actions in Forerunner 45.

On the other hand, you will get a similar amount of activities in 45 Plus as well. However, to uplift it a little bit from the previous model, Garmin has added the swimming feature in it as well. As the model is swim-proof, you won’t have to worry about it!

Both 45 Plus and Forerunner 45 has a decent memory status and, thus, can store around 200-hour of data. You can sync each of them through your smartphone by using the Garmin Connect app quite comfortably. 

However, even though there are a lot of similarities available in both of these watches, the newly-released model wins the Garmin Forerunner 45 vs 45 Plus quite comfortably. For starters, the latter comes with the coveted Race Predictor feature. 

As the name suggests, it can predict the time that you would take to complete your target. For example, if you aim to run for 10,000 steps, then the model will show the time limit after you have completed 500 steps. 

Once you are done with your exercising, it will let you know about the recovery time. It can do so by using its Recovery Time Advisor feature. Unfortunately, both of these facilities are not available in Forerunner 45, and this is the main difference between Garmin Forerunner 45 and Forerunner 45 Plus.

Winner: Forerunner 45 Plus

Tracking and Health Monitoring: Forerunner 45 Plus and 45

Garmin Forerunner 45

Both Forerunner 45 and 45 Plus are quite efficient in this aspect. For starters, they do feature a GPS tracking system, which offers a decent and accurate tracking for most of the time. Each of them comes with the GLONASS feature that real-time position with 100% accuracy.

Also, there is a Galileo Navigation System available in them, which can navigate you through unknown territories. In addition, there is an Accelerometer available in the models as well. With it, you will be able to know about your current running speed. 

However, the main talking point in these products is definitely the availability of the Heart Rate Monitor system. With it, you can keep track of your real-time heart-rate. Moreover, you can also oversee the resting rate of your heart for seven days.

Also, there is an alarm system available in both of these models that alerts when your heart beat-rate hits an abnormal speed. However, in the former variant, this feature used work a little bit slower.

Nonetheless, it does not happen in the aspect of the new one, as it has been made by implementing the exclusive Garmin Firstbeat Analytics. 

With it, the Garmin has boosted the accuracy in fitness, health, and other aspects of the device. 

So, even in the future versions, Garmin will keep using this Firstbeat technology to provide its users with better updates. So, in a way, you can consider the Forerunner 45 Plus to be the best Garmin Smartwatch

Winner: Forerunner 45 Plus (Due to FirstBeat Technology)

Music Controlling and Call Notifications: Forerunner 45 Plus or Forerunner 45

As mentioned before, you can sync both of these devices with your smartphone through the Garmin app. It, in turn, will enable you to change the song, which you are currently listening to, more proficiently.

Furthermore, you will also be able to take your calls from either home or office with a single click on the watch. However, as each of the models does not come with the touch screen feature, you may have some issues with checking these things. 

Anyways, moving on, with both the watches, you will also be able to obtain your Facebook, WhatsApp, and Instagram-based notifications pretty conveniently. Also, there is a ‘Do Not Disturb’ option available to help you stay away from the earthly materialisms. 

Lastly, if you want to, then you can also customize the options in your own way. Sounds great, right? So, unfortunately, no one is going to win the battle between Garmin Forerunner 45 and 45 Plus in this aspect. 

Winner: Draw

Battery Life: Garmin Forerunner 45 or Garmin Forerunner 45 Plus

Unlike a few other things, the battery life of both models remains unchanged. To make it simple, if you own either of these products and are using it in the smartwatch mode, then their battery would last for seven days.

Conversely, if you have activated the GPS mode in it, then both of them would be able to work for around 14 hours. Also, it takes the watches only around two hours to replenish its battery entirely. 

Winner: Draw

Extras: Forerunner 45 Plus and 45

The extras of the models are quite the same as well. For example, both of them are water-resistant, scratch-resistant, and have a sleep tracker in them. Moreover, they also display the current weather condition and feature an in-built pedometer in them. Also, the straps of the devices are removable and replaceable. 

However, if you are thinking about buying a cheap Garmin smartwatch, then we would suggest you opt for 45 Plus. It comes with a price range of under £140. However, even though being a former variant of the same, the Forerunner 45 is priced at approximately £160. So, if you do compare at the features, then 45 Plus would be the ideal budget watch for you. 

As of now, Garmin Forerunner 45 Plus is available in the UK market only, and you can buy Garmin Forerunner 45 Plus at

 Winner: Forerunner 45 Plus

The Bottom Line 

So, as you can see, the 45 Plus defeats the Forerunner 45 in most cases. However, it is still quite early to judge the capabilities of the same, as it is a new release. 

So, it may come with some technical bugs that might affect your overall experience. Nonetheless, once found, the buggy issues will be eradicated by Garmin promptly. So, there is no need to worry about it!
