Both versions of the Samsung Galaxy Watch 4 feature a redesigned frame that allows for a gapless transition from the smartwatch casing to the strap. The crown button has also been changed from a traditional round crown and side button combination to a rectangular one. Despite these subtle changes, the Galaxy Watch 4 pays homage to past Galaxy Watch models. The Galaxy Watch 4 Classic features a rotating bezel that is an excellent fidget spinner with convenient navigation tools. Since Samsung Electronics’ first Galaxy Watch adopted this bezel, it has come to symbolize the product in the same way that the S Pen symbolizes the Galaxy Note smartphone (previously?). – It is as iconic as the S Pen on the Galaxy Note smartphone. Therefore, Samsung’s choice to remove the rotating bezel from the new Samsung Galaxy Watch 5 is controversial. The centerpiece of the Samsung Galaxy Watch 4 is a software refresh that combines the look and feel of Samsung’s existing Tizen platform with Wear OS features. It has a full range of fitness features, long battery life, and a comfortable design. There are some compatibility issues that may frustrate some potential buyers, but primarily the Galaxy Watch 4 is an interesting iteration of Samsung’s top smartwatch formula. As mentioned, both models are available in small and large sizes. Our Samsung Galaxy Watch 4 review unit is the larger 44mm size, with a 1.36-inch AMOLED screen; there is also a 40mm Galaxy Watch 4 with a 1.19-inch display; the Galaxy Watch 4 The Classic comes in 46mm and 42mm (we have the smaller one) and these have similar sizes and the same screen size.
