Samsung Gear S3 vs Galaxy Watch In-Depth Comparison

Design, Display, and Color

Samsung Galaxy Watch

The Samsung Galaxy Watch comes in two models: either a 1.8 x 1.9 x 0.5 inch one that weighs 2.2 ounces, has a 1.3 inch display and is available in black, blue, and silver, or a 1.6 x 1.7 x 0.5 inch one that weighs 1.7 ounces, has a 1.2 inch display and is available in black, purple, silver, red, yellow, pink, grey, and brown.

They both flaunt a sporty look that looks fantastic with a textured rubber band. Its circular form suits the sporty style, and the super AMOLED display with resolution of 360 x 360 pixels makes it immersive.

Corning Gorilla Glass DX+ is protected and makes it withstand shocks and scratches.

Gear S3.

Although the Gear S3 comes in two versions of 22-millimeter rubber straps (can be replaced by any other regular 22-millimeter strap), they vary in that the Frontier has a rugged look of wide and textured buttons, whereas the Classic has a sleek one (as the name implies) with protruding metallic buttons.

The measurements of both trackers are 1.8 x 1.9 x 0.5 inches but the Frontier weights more at 2.1 ounces and the Classic weights 2.0 ounces.

All show the time, even if disabled, and their screens contain animations as they have a complete variety of 16 million colors.

All trackers do have a 1.3 "super AMOLED circular display with a resolution of 360 x 360 pixels (278ppi). Thanks to the reinforced Corning Gorilla Glass SR+, shocks and bruises caused by drops are minimised.

Winner: Galaxy Samsung Watch.

  • Health features.
  • Galaxy Watch Samsung.

The Samsung Galaxy Watch will give you an estimation of your sleep period and efficiency, as it tests the 4 stages of sleep with its measurement device.

The controlled breathing sessions will help you reduce stress levels by controlling your breath if you're nervous or anxious. It also counts the calories that you consumed during the day.

Gear S3
The Gear S3 keeps track of the calories you've consumed during the day and the path you've been walking along. It also tests the length and consistency of your sleep, as it has sleep-tracking.

Winner: The Samsung Galaxy Watch.

Fitness Features

Samsung Galaxy Watch

With no plans or hassle, you can easily go from one exercise to another as the Samsung Galaxy Watch offers you a detailed monitoring of all activities.

This can identify 6 different types of movements automatically, and that number can be expanded up to 39 workouts and more, while monitoring the heart rate at the same time.

The GPS, barometer, and altimeter combination lets you know where you've been, where you're, and where you're going.

This is also water-resistant up to 5 ATM (165 feet), which means you can use it when you go swimming to control your heart rate, so you can take showers without having to take it off.

You should still dry it off and never dive with the watch on afterwards, however.

Gear S3.

Once it comes to activity monitoring, the Gear S3 doesn't really go far because it's only confined to the accelerometer that detects walking, and the barometer that detects floors climbed.

It has an optical heart rate monitoring app, an integrated gyro, GPS services, and an ambient light sensor making it ideal for general activity tracking.

It is not waterproof but, based on its IP68 rating, it avoids water and dust over 1.5 meters and 30 minutes.

Winner: Galaxy Samsung Watch.

Gear S3 Frontier versus Galaxy Watch:

Galaxy Watch Samsung.

Using the "My Day" watch face app, you can show a rundown of your schedule 10 hours ahead, whenever you need it.

A lot of easy applications are available that can fulfill your every need (including Spotify, Glympse, Uber, Strava and more).

One feature worth noting is the watch's ability to make payments and transactions through the NFC Samsung Pay. It has a Bluetooth model and a standalone LTE app that essentially makes it a phone as well as being able to get calls with a tap and check your messages.

A really cool aspect the Samsung Galaxy Watch offers is that it gives you full control over your appliances and devices such as your TV, vacuum cleaner, or air conditioner.

It is focused on information gathered from your everyday activity and sleep habits, and is activated by the Home IoT app that transforms it into a platform for home automation.

The Gear S3 Frontier and Classic both have built-in microphones, but only the S3 Frontier makes voice calls.

They run on Tizen's operating system, and are powered by a touchscreen, twin buttons and a rotational bezel that makes it easy and seamless to use.

When it comes to applications, plenty of choices are offered like Spotify.

And if you're searching for health-related games, music, social media or keeping your alerts checked on your Gear S3, you'll find it.

You will enjoy a lot of data and mount it on your watch with 768 MB of RAM and 4 GB of internal storage instead of having to connect it to external sources.

The networking choices are also varied with the S3, as it is fitted with choices such as 3G / LTE, Bluetooth 4.2, WiFi b / g / n, NFC, MST and A-GPS (with GLONASS).

Winner: The Samsung Galaxy Watch.

Winner: The S3-Gear.

What one is better overall than the Latest Samsung Galaxy Watch or Gear S3 Frontier?

As is apparent throughout the contrast, the bottom line is that the fresh, improved Samsung Galaxy Watch beats its competitor in several respects.

While the Gear S3 is a pretty decent choice for a smartwatch, it doesn't perform as well as a fitness tracker, and when you compare it to its competitor, it falls short of certain features and still isn't significantly more affordable than the Galaxy Watch or has a markedly longer battery life.

One could purchase the Samsung Galaxy Watch for a couple of extra dollars and enjoy all the extra features it has to offer, as well as the nice balance and combination of being a smartwatch and a fitness tracker.

You can check out the Fitbit Charge 3 if you are looking for a wearable that is more affordable than all of these choices and yet provides the same basic fitness features.
