If it is based on the presence or absence of physical pointers and the presence or absence of a touch screen design, it can basically be divided into three categories.
The first category is the use of physical pointer + traditional dial design smart watch, the design is consistent with the traditional mechanical watch, the common material of the fuselage is metal, generally 304 stainless steel, comfortable to wear, more textured, with certain waterproof performance, simple In fact, it is a quartz watch with a built-in smart chip. The common one is a built-in button battery, and the battery life is generally more than one year. But there are also smart watches with built-in lithium battery + wireless charging.
The second type is the same design using the physical pointer + traditional dial. One is to design a small LCD screen inside the dial to directly display information such as motion data, and the other is to design the watch to display. The screen is used to display text information and other content, but there is some overlap in the perception. For the body material, some are made of metal, and some are made of ABS plastic.
As for the third category, it is a smart watch with touch screen design, comes with an operating system, no physical pointers, such as TICWATCH S, the common material of the fuselage is ABS material, and supports the dial customization function.
