Mechanical watches are powered by a coiled spring known as a mainspring. As this spring uncoils, the amount of time that the watch can run diminishes. This remaining amount of time is referred to as the power reserve, winding indication, or up/down indication. An indication turning through an angle or a linear indicator appears on the dial to display the power reserve, similar to a car’s fuel gauge.
Today. I will recommend you three watches, such as Casio, Tissot and Wishdoit watch. The three brands of watches have their own advantages and characteristics, and let me explain them in detail.
During the deep dive of the watch, as the water pressure increases, there are more helium molecules in the water than under the water molecules, and the tiny helium molecules will squeeze into the case from the gap of the watch under the action of strong pressure. At this time, the pressure in the case gradually increases, and the internal and external pressures are basically balanced. In this way, the watch can be well waterproofed in the deep sea and prevent the case from being broken and deformed.
Though technology has badly occupied the world, the advent of new tech products is continuously taking the place of old ones, which you can call classic, cultural, and traditional. And sadly, watches have no exception to it.
Those who still wear them are either habitual or take them for fashion. But don’t think that the timepieces are outdated. Though their primary purpose is to show the time, they are symbols of wealth and goodness and indicate a person’s taste.
