The Knowledge Of The Wrist Watch

Today, let's take a look at the knowledge points that must be known.What different of the Mechanical watches and Quartz Watches. The advantage of Quartz watches is that they are accurate, but the batteries need to be replaced regularly. The advantage of a mechanical watch is that it is highly ornamental, with manual and automatic winding, and the disadvantage is almost error, and the maintenance cost is higher than that of a quartz watch. If a mechanical watch is not worn, it will stop moving. Automatic Mechanical Watches do not require manual winding, which is wrong. Automatic is the continuous swing of the pendulum on the movement to drive the automatic gear train for winding, which simply requires the human arm to swing. When the amount of movement of the wrist is enough, it is not necessary to wind the string, otherwise, it needs to be wound.

Knowledge 2 : Some people misunderstanding of 30 meters waterproof .The waterproof performance of the watch is also easy to be misunderstood. Usually the watch said 3ATM (BAR) .5ATM, 10ATM, is waterproof 30 meters, 50 meters. But it does not mean that the watch can be placed underwater within 30 meters, its real meaning is that it can resist the pressure of water at a depth of 30 meters. Generally speaking, 30-50 meters are only daily waterproof, and cannot go swimming.
Knowledge 3 :Did you know you can't wear a watch when you're in a hot spring? even a Dive watch. There is also a common misconception that all watches are not resistant to hot water, so they cannot be worn in hot baths and saunas. It is very easy to damage the watch. Even diving watches cannot be washed in hot water. Because of the principle of thermal expansion and contraction, water will enter the inside of the watch from the gap, which will accelerate the aging of waterproof parts for a long time.
