Design and Build

Garmin, known for developing specialized GPS tracking devices has incorporated its advanced technology into smartwatches. We were surprised to find how advanced Garmin's collection of watches are. Their watches offer a long list of features that make them one of the best brands to buy from.

Garmin knew exactly what they were doing when they designed this one. Even though this option is favored heavily by runners, it is a wonderful option if you prefer walking and working out as well. From our research, we found that this product features a very user-friendly interface with 5 buttons. With the 5 button design, Garmin allows users to easily remember how to operate different settings and modes.

The design of this option is very trendy, especially with its 1.2’’ color display. Speaking of the display, we’d like to mention the quality of the screen. We found that Garmin used a chemically strengthened glass which is made for everyday use and can be worn in all types of weather. Another feature we found that users loved was, even in direct sunlight, whether you are at the beach or in the mountains, there was absolutely no glare and it was very easy to read. For this, Garmin uses its Chroma Display technology to make this happen. We find it amazing how Garmin can create such a sleek and small product with so many features.

As a fitness watch, we discovered that users also seek options that are water-resistant. With this option by Garmin, you will have the peace of mind knowing that it can get wet. Whether you are showering, swimming, or got caught in the rain, you are safe to use this smartwatch. We believe that this is an important feature because are surrounded by water and sweat, so if the materials used for the smartwatch is not water-resistant it will fall apart quicker. We can all agree that, if we are investing our money into a smartwatch, we want it to be durable and last.

Lastly, we’d like to share that, with this product by Garmin, you can also add your own little touches. Garmin offers this smartwatch in 5 additional colors and has an array of different colored bands to match your mood or outfit for the day. And the best part of it all is, switching out the bands are easy, tool-free, and painless. As a rule of thumb, we always recommend doing a test fit of the watch on your wrist to make sure it fits properly.

Battery Life Span

Surprisingly, when using Smartwatch Mode, this option by Garmin can last up to 7 days before needing a charge. Compared to other options on the market, being able to hold a charge for this long is considered pretty good.

On the other hand, if you choose to use its GPS Mode, you will only get up to 14 hours of battery life. And say you want to listen to music too, this will decrease your battery life to up to 5 hours. Even though the battery life in this specific model isn’t as long, its additional features make this watch worth checking out.

In conclusion, we all know that the more you use the watch, the more battery it will use. So with that being said, if you are in search of a watch that has GPS capabilities and can store and play music at the same time, we highly recommend this option by Garmin.

Contactless Payment

Do you worry about how you’re going to carry your phone and wallet with you while you run or work out? Well, you will not need to worry about this smartwatch.

Users indicated that this feature comes in handy more than you think. This is a new feature that we are seeing throughout all different devices. Not only will this keep your phone and wallet safe but you’ll be able to solely focus on your workout, handsfree.

Running and Training Mode

Since this smartwatch was designed specifically for runners, we took this feature into consideration. As we mentioned above, compared to other Garmin Forerunner models, you can store up to 500 songs on this watch, giving you a plethora of music to listen to on your next run. For the avid runner, we are pleased to inform you that this option by Garmin is equipped with today’s advanced running dynamics. From tracking your ground contact time and cadence to your stride length, balance, and vertical ratio, this smartwatch by Garmin will help you improve your overall performance for your next race.

These biochemical measurements are crucial in improving your form. We also found that Garmin offers a heart rate monitor strap and additional running dynamic pods, sold separately, that you can pair with your smartwatch for additional metrics.

Garmin offers a performance monitoring tool, Training Status, which is already built into this watch. Without having to check your progress every second, you can trust that this tool is accurately tracking your exercises and evaluating your workout history. Based on your history, it will then provide you with productivity feedback. This breaks down whether you need to improve in one area versus another and will also let you know if you are overachieving and peaking.

With today’s technology, we are not surprised to see such a small device being able to track all your active movements and provide feedback based on your activity history. Garmin believes that this type of technology will greatly assist in helping you reach your fitness goals.

By connecting to Garmin’s, Connect IQ Store, you will be able to browse all the different features you can add to your smartwatch and mobile device. We found that new apps are uploaded to the Connect IQ Store daily, so we are positive that you will always find something you can use. For instance, you can add the AccuWeather Minute Cast app to your device and this will help you track nearby storms and inclement weather by the minute. This will surely come in handy by letting you know if it will rain while you are training outside.

Even though this option by Garmin is priced on the high end of the spectrum, we believe that its overall features outweigh its price. From being able to store up to 500 songs and tracking your progress, this is where this product shines. Having up to 7 days of battery life when in activity/ tracking mode is also a great feature. Don’t let the price tag shy you away from this superior device.
