Fitness trackers without display

Without display

— devices that do not have displays at all.

Most of the models in this category are fitness trackers (see "Type").

Another variety of models without a display is a specific kind of smartwatch: wearable devices that look like a classic wristwatch with a needle dial. Such a dial can be supplemented with luminous indicators, but even in this case, it is not considered a display. Such solutions are designed primarily for those who prefer watches of traditional design and, at the same time, would like to enjoy the benefits of a smart gadget. Devices of this type are designed for notifications — about calls, incoming messages, etc. Due to the lack of a display, power consumption is extremely low, many of these devices can work for weeks or even months on a simple battery like CR2032.
