'Galaxy Watch 4' photo review, smart watch for Android with Google Wear OS

The smart watch '

Galaxy Watch4 ' developed by Samsung appeared on September 22, 2021. With 'Wear OS Powered by Samsung' installed, apps such as Google Maps can be installed, and body fat percentage and muscle mass can be measured by bioelectric impedance (BIA) analysis. I got this smartwatch with other features that are perfect for health care, so I immediately took a picture of its appearance.

The package of Galaxy Watch 4 looks like this.

The contents are the Galaxy Watch 4 main unit, wireless charging dock, and quick start guide.

This is the main body of Galaxy Watch 4. The color is pink gold.

A barometric pressure sensor is located at the top of the main unit.

There are two holes for the speaker on the left side.

Two buttons are placed on the right side of the main unit, in a position that comes to the front when attached to the left arm. The left is the 'back key' and the right is the 'home / power key'. There is also a small hole for the microphone.

The back of the main body looks like this. An optical heart rate sensor is located in the center.

The belt is made of soft silicone with a silky feel.

The actual mass is 48g. The main body size excluding the belt is 40.4 mm in height x 39.3 mm in width x 9.8 mm in thickness.

When I measure the 'length of the belt when it is attached', the maximum circumference is about 21.5 cm ...

The minimum was about 16.5 cm.

When I actually wear it on my arm, it looks like this.

The belt can be attached and detached by sliding the silver protrusion at the base of the belt inward using a nail or the like.

The belt can be swapped up and down, or replaced with a commercially available belt. In addition, compatible belts are '20mm wide'.
