Samsung Galaxy Watch 4 Classic: Stylish design meets robust features.

It is not without reason that Samsung chose the addition “Classic” when naming this smartwatch. Its design impresses with a very stylish touch and is also reminiscent of the Gear S3 Classic, for example. The main feature is the rotating bezel, which functions as a control element alongside the two buttons on the casing’s right edge. The Samsung Galaxy Watch 4 Classic (check out the Samsung store) is available in two sizes to appeal to both men and women.

The diagonal of 42 millimeters is intended for slimmer wrists. A 1.20-inch Super AMOLED display is installed. It has a resolution of 396 x 396 pixels. The larger option is characterized by a diameter of 46 millimeters. The screen here measures 1.40 inches, and the corresponding resolution is 450 x 450 pixels.

Strong materials for a long lifetime

The touchscreens are each protected by the very robust Corning Gorilla Glass DX – it is one of the reasons why the Samsung Galaxy Watch 4 Classic has received certification according to military standards. It proves to be water-resistant up to 50 meters, so it can be worn while swimming without any problems.

The smartwatch’s casing is made of stainless steel. The smaller variants weigh 46.5 grams, the larger ones 52 grams. The Galaxy Watch 4 Classic is available in completely neutral black as a smaller and larger version. In addition, the more compact version comes with a silver case and a white strap. Alternatively, the 46-millimeter version is available in the combination of silver and gray.

Everyday life, health or sports: A smartwatch for everyone

One of the special features of the Samsung Galaxy Watch 4 Classic is that it is the manufacturer’s first smartwatch to use a Google operating system since 2013. However, the South Koreans have upgraded Wear OS for their own models with One UI Watch – a modified user interface characterizes the watches accordingly. Users have the option of downloading applications via the Play Store, which expands the range of functions. Among other things, it is possible to be navigated by Google Maps or to enjoy music via the streaming service Spotify.

Speaking of music: If you want to store your favorite tracks on the Samsung Galaxy Watch 4 Classic, you will find a 16-gigabyte storage, of which 7.6 gigabytes can be used freely. Playback is done via Bluetooth headphones. The smartwatch not only notifies when there is news on the paired cell phone.

The LTE models with integrated eSIM can even operate completely independently of a cell phone if required. If the cell phone remains at home, the wearer can still be reached at any time and also reach their contacts. The Samsung Galaxy Watch 4 Classic also implements contactless payment thanks to a built-in NFC chip. The user can choose whether to use Google Pay or Samsung Pay.

The Samsung Galaxy Watch 4 Classic is a great supporter for everyday tasks.

New features and technologies

Samsung has implemented an absolute innovation with the integration of a bio-impedance sensor. Such a technology has been common for body fat scales until now. However, the smartwatch can also determine how high the proportions of muscle mass, fat and water are. The manufacturer’s own Bio-Active sensor is responsible for this. A measurement takes just 15 seconds.

And the Samsung Galaxy Watch 4 Classic has another unusual function: It provides a particularly detailed sleep analysis. It goes far beyond registering the deep and light sleep phases as well as the moments when the user is awake. It also monitors the oxygen saturation in the blood.

If this is low, health problems such as sleep apnea can be detected. On top of that, the smartwatch even detects whether its wearer has been snoring, and if so, for how long. The prerequisite for this, however, is that the smartphone is placed near the pillow. It has to be a Galaxy device. The same condition also applies to taking a blood pressure reading or having an ECG created.

Ultimately, active sports enthusiasts also get their money’s worth. The Samsung smartwatch supports a variety of workouts that can be recorded without any problems. It automatically recognizes many types of workouts. The Galaxy Watch 4 Classic records outdoor routes via GPS, GLONASS and Beidou.

For mutual motivation, friends challenge each other with the same smartwatch. They receive points for their movement and corresponding badges for successes. The watch’s battery life is 40 hours regardless of the run. With a quick-charge function, it is possible to supply energy for ten hours within 30 minutes – which can easily beat the current Apple Watch standard.
