Description

What is mechanical watch ? A mechanical watch is a watch that uses a mechanical mechanism to measure the passage of time, as opposed to modern quartz watches which function electronically. It is driven by a spring (called a mainspring) which must be wound periodically. How to Wind a Watch 1.Remove the wrist watch from your arm or storage. It is not advisable to wind a watch while it is on the arm because, with the watch tight against the skin, the winding motion may not be effective. 2. Hold the watch face up in your left hand. Reverse the position, of course, if left-handed. The stem may have several settings, including settings for time, calendar, alarm, or time zone. The settings are located at little "clicks" as you pull the stem out or push it in. Use trial and error to feel the clicks and identify the winding position. 3. Use the thumb and index finger to carefully pull out the watch stem by the stem's top or "crown." This can be difficult because you do not want to over-wind the mechanism. Be conservative; stop when you feel resistance, but if the watch runs down sooner than you like, you know you did not quite hit the maximum tension. In time, you will develop a feel for the resistance. 4 Turn the stem forward repeatedly until some resistance is felt. Depending on the size of the watch, 20 to 40 forward turns should lead to resistance; over-winding will strain or break the mechanism. 5 Press the crown to return stem to its place. 6.The Automatic watch is powered by the motion of the wearer's wrist. If the watch is not worn for 8 or more active hours per day, it will run slower than usual or even stop briefly. You need to shake the watch or wind it when start to use it
