Types of Mechanical Watch
Mechanical watches can generally be divided into the following two types: hand chained watches and automatic chained watches (AUTOMATIC). The power source of the mechanical watch is the spring in the movement, which drives the gear and then pushes the watch needle.
Features of mechanical watch
1. Unlike quartz watches, mechanical watches move continuously.
2. Due to the complex movement of the mechanical watch, the travel time error is relatively large (depending on each brand), and the general allowable range is ± 45 seconds. The movement error of the observatory is relatively small
The error is normal within - 4~+6 seconds. The timing error of the mechanical watch cannot be accumulated, and the watch needs to be adjusted after a period of time.
3. The process is fine and easy to use. It can take more than 35 hours to wind up.
4. The movement has a long service life.
5. The appearance is thicker and heavier than the quartz watch (depending on each brand). Some brands are also very thin, but they are generally manual mechanical watches.
Error of mechanical watch
The allowable error range of the mechanical watch is ± 45 seconds/day, and the average error range of the movement certified by the Observatory is between - 4 seconds/day and+6 seconds/day. The specific error depends on the movement used by the watch, not on the principle that the higher the price, the smaller the error. The power source of the automatic mechanical watch is the energy generated by the wrist swing of the wearer to wind up, A fully winded automatic watch can last for about 35 hours: if you wear it normally every day, it can operate for about 15 hours. If you don't wear it for more than a period of time, or if you don't swing enough (the wearer has less exercise), it will cause the watch to stop. It is recommended that you wind the watch before wearing it again.
Recommendations for use of mechanical watch
1) The watch with manual winding movement should be wound at the same time every day as much as possible, so that the watch has enough energy to operate in the next 24 hours.
2) The energy of the watch with automatic winding movement comes from the movement of the wearer's arm. Therefore, it is not necessary to manually winding under normal wearing conditions. Only when the wearer's movement is not enough to add enough energy to the spring, the method of manual winding can be used to compensate, and the rotation of the crown during winding is controlled within 30 turns.
3) If you have not worn an automatic winding watch for more than 40 hours, you should turn the crown 30 times when you wear it again to restart the drive system of the movement.
4) In order to prevent moisture from seeping into the case and maintain the waterproof performance of the watch, please ensure that the crown is always locked.
Resolution method
Usually, Quartz or Automatic will be marked on the face plate or back bottom cover of the watch, so that the quartz watch or mechanical watch can be clearly distinguished. Another way to identify is to look at the second hand of the watch as a walking mode. If the second hand is a jumping walk every second, then this watch is a quartz watch; On the contrary, if it is not a jumping walk, it is a mechanical watch. If you find that the second hand walks for two or four seconds at a time, this is still a quartz watch, but when you find that your second hand walks in such a gait, it is sending you an alarm to replace the battery. Some quartz watches with better design have this device. They will walk for four or five seconds at a time to tell you in advance that it is time to change the battery.
Common sense of mechanical watch maintenance
Principles for adjusting time of mechanical watch:
If the mechanical watch is not used for a long time, the spring of the mechanical watch will relax until the watch is still. At this time, if you want to wear it again, you must re-wind it quickly, and then calibrate the time. Generally, when the spring of the mechanical watch is at its most loose time, it will show that the clockwise and minute needles will slow down or become faster. Because of this, you should wind it up first, so that there is no standard power drive pointer after the calibration time, Even if it is a semi-automatic chain-up watch, it should be manually chained to eight minutes full (full chain-up will break the spring) before time calibration.
Steps for self-cleaning, protection and maintenance of mechanical watch:
(1) Wipe gently with a soft cloth and soapy water
(2) Wipe with clean water with soft cloth
(3) Wipe with dry soft cloth
(4) The ventilated place is dry in the shade
(5) Don't give ultrasonic cleaning casually
