There are many kinds of accessories of women such as the cosmetics, headdress, jewelry and so on. Comparing to women, men are quite simple creatures. The only accessory that they really take serious is the watches. Almost every man owns his watch. The watches on man’s wrist speak volumes about their individuality, taste of style or even the success. Therefore, purchasing the watches is a very personal and important decision to men. To make a good understand of the men, you should firstly make a good understanding about the watches on their wrists.
Classified according to the different power sources, watches are sorted into two categories: Mechanical watch and electronic watch.
Mechanical timepieces are still used, usually powered by a spring wound regularly by the user, for example using a stem winder. This type of watch allows for a constant winding without special action from the wearer: it works by an eccentric weight, called a winding rotor, which rotates to the movement of the wearer’s body. The back-and-forth motion of the winding rotor couples to a ratchet to automatically wind the watch. The spring drives an escapement, which consists of a lever that moves back and forth against a gear, keeping the gear moving at a specific number of times per second, usually four or five. That gear, in turn, drives all of the other gears of the watch that turn the hands on the dial. See main article self-winding watch.
The first use of electrical power in watches was as a source of energy to replace the mainspring, and therefore to remove the need for winding. The first battery-powered watch, the Hamilton Electric 500, was released in 1957 by the Hamilton Watch Company of Lancaster, Pennsylvania. Tuning fork watches use a 360 hertz tuning fork to drive a mechanical watch. The outstanding engineer Max Hetzel was the first one to use an electronic device, a transistor in a wrist watch. Thus, he developed the first watch in the world that truly deserved the qualification “electronic”: the world-famous “Bulova Accutron”.
These two watch terms are often confused, although they refer to two very different things. This is just one example of how important it can be to better understand watches and how they work. Females, as well as males, are in the need to know more about the watches in order to make a better understand about the other half.
