Last week, unofficial renderings gave us our first glimpse of what the Samsung Galaxy Watch Active 4 might look like. However, it appears that it may have been a misrepresentation, as official promo images show the same wearable labeled "Samsung Galaxy Watch 4."

The Samsung Galaxy Watch 4 image was obtained by 91mobiles through "reliable industry sources." From the fonts to the layout, the design of the purported marketing materials certainly feels like Samsung's press materials, but it's not the most difficult style to imitate.

Assuming the images are legitimate, the most striking thing is that the physical rotating bezel for selecting apps and navigation is gone. This was not part of the Galaxy Watch Active series, but the second generation introduced a digital rotating version to compensate, with a tactile buzzer simulating actual resistance. Samsung is believed to have a similar plan here.

Nevertheless, it is possible that Samsung will keep the physical version for another model. The well-connected Max Weinbach, who has a solid record when it comes to Samsung developments, claims that both styles exist.

In any case, 91mobiles claims that the device pictured will come in 40mm and 44mm sizes with built-in GPS; the Galaxy Watch 4 boasts 5 ATM water resistance, Gorilla Glass DX+, and MIL-STD 810G durability, It could be quite rugged. As can be seen from the photos, it will be available in black, white, dark green, and rose gold.

In terms of novelty, Weinbach has another interesting piece of information. He claims that the Galaxy Watch will have a BIA sensor. This stands for "bioelectrical impedance analysis," a system used by smart scales to estimate body fat percentage by passing a small electric current through the body. Since fat and muscle have different compositions, the resistance of the current can be used to estimate their respective body compositions.

In the case of the wearable, the user would complete the circuit by touching a part of the watch with his or her hand. From the user's point of view, it would function in the same way as the Galaxy Watch 3's ECG scan.

While the benefits of having such technology on the wrist should be obvious, ensuring that it works is a rather large challenge. Even the BIA sensors built into scales have reliability issues, so developing a wrist-worn type of sensor could have its own problems. However, with Apple reportedly planning to include blood glucose and other health indicators in its future Apple Watch, it would not be surprising if Samsung pursues something like this.

If the 91mobiles leak is accurate, we should know soon enough. According to the site, Samsung will announce the Galaxy Watch 4 this week on June 28.
