An insight into how watches work
We have been using watches for a long time. Great advances in technology have changed the field of watch making so there are many different varieties of watches and brands. Each one has got his own preferences in terms of strap type, color, dial material, presence or radium, analog or digital type and gold or silver plated and so on. There are also solar watches, power delivered from a solar panel. Solar panels help in the energy conversion from heat energy to electrical energy and then into power (mechanical energy). During the night, these watches are able to function well as they have stored the sunlight power received in the morning from rechargeable cells. Indiglo watches will convert the electrical energy into light energy by acting on the phosphor atoms.
Earlier watches were used only for showing the exact time in hours, minutes and seconds. Some womens watches were later developed to show the date, day of the week. If you are in Australia, you can use some of the latest watches to tell you the time in America. So thus watches that perform time zone calculations can be seen. Based on the movements of the smaller and longer hands of the watch, we call them as the quartz watches or the mechanical type. There are two types in the category of mechanical watches and it includes automatic watches and hand wound watches.
The spring of the automatic watch is automatically wound. The movement between the arm and wrist causes the winding ,they are otherwise known as kinetic watches. They can store power for close to 36 hours. The other type of mechanical watch is the hand wound type. Quartz was used in the watches from the 1970’s. The quartz crystals that are used in battery powered watches oscillate. As it oscillates, every second pulses are created, which cause the watch hands to move. Thus the spring action in mechanical watches is replaced by the action of quartz in these watches. Swiss watches are very famous around the world. They have good expertise in the watch making field.
Watches that are of high quality are usually water resistant. The test pressure test indicates the atmosphere or the equivalent water depth at which the watch is resistant. It gives us the environmental condition in terms of atmospheric pressure or depth in water, at which the watches can be resistant. For example, if the watch is said to have passed the test pressure of 50 ATM, then we consider using it in swimming pools also as it can be resistant to water at 5o meters depth. But this is in case of an accident where the watch falls in to the water. This does not imply that watch can withstand water if we wear it every day in the swimming pool.
