How should you clean and maintain a watch?

　　As a watch is worn for longer periods, it inevitably becomes dirty, which not only affects its appearance but may also damage the internal movement. So how should a watch be cleaned and maintained? Below, Yaoya shares methods for cleaning and maintaining watches, hoping to be helpful to everyone.

　　Mechanical watch cleaning methods

　　1. General watch cleaning tools generally include a watch brush and specialized watch cleaning fluid. Cleaning with ordinary tools is very simple, and the cleaning fluid selected is aviation gasoline No. 120. Because gasoline contains a certain amount of impurities, it is best to filter gasoline No. 120 using filter paper before use to remove impurities. Otherwise, parts cleaned with unfiltered gasoline will develop a layer of white frost on the surface. Cleaned parts must be blown or baked dry. If the movement parts have a lot of sludge or are too dirty, they should first be soaked in a petrol cylinder for a while. If necessary, first use a brush to remove the dirt on the Tissot watch or use a wooden stick to remove the sludge, and then clean them in clean gasoline. In short, movement parts must be cleaned thoroughly and cleanly, without any negligence.

　　Second, clean using a watch cleaning machine. Cleaning components with a machine is highly efficient. Cleaning solutions include petrol, alcohol and trichloroethylene (13) and other solutions. Use a trichloroethylene solution for cleaning plates. The cleaning machine commonly used for watch repair is a horological cleaning machine, as shown in figure 1-17. It features speed regulation, time control, clockwise and anticlockwise rotation of the working head, and lifting functions. It also has three bottles containing cleaning solutions, which must be covered after cleaning the watch to prevent solution evaporation and contamination. Additionally, there is an empty tub used for spin-drying the watch after cleaning. The first bottle contains less clean solution; the second bottle contains clean solution; the third is distilled water for rinsing and dehydration. Of course, other arrangements can be made according to the process flow. To avoid damaging parts due to collision during cleaning, wire mesh baskets of different shapes made of copper should be used to hold different parts. Place these baskets together and secure them with a frame to clean them simultaneously, allowing several watches to be cleaned at once. For watches with heavy sludge, it is best to remove the sludge beforehand before cleaning with the machine.

　　Quartz watch cleaning method

　　1. Clean the circuit with a professional cleaning solution. The quartz watch circuit consists of solid-state circuitry, a quartz resonator, a trimmer capacitor, and a printed circuit board. Due to the special nature of watch electronic components, industrial 99% anhydrous alcohol (absolute ethanol) or trichloroethylene is generally used for cleaning. During cleaning, it can be placed in a container, but the time does not need to be too long. Gently clean it clean with a cleaning brush, take it out, blow dry or bake dry with an air blower, and then clean it thoroughly with a silk cloth or long- bristled tool.

　　2. Gently clean the coil holder with a softer brush. Precautions for cleaning the quartz watch coil holder: Because the outer layer of the quartz watch coil wire has no protection, it must not be cleaned inside a container, and generally the coil should not be held by hand. The correct method is to hold the two magnetic conductive ends of the coil holder with your hand and gently clean it clean with a softer brush (be careful not to break the lead-out wire of the coil at the lead-out board soldering point). Do not use petrol to clean the quartz watch coil lead-out board.

　　3. Wipe the motor with an eraser or willow wood stick. Precautions that should be taken when cleaning the watch motor: The magnetic steel and copper sleeve of the quartz watch motor rotor are fitted together by metal glue bonding, so they cannot be cleaned with cleaning fluid. Generally, an eraser or willow wood stick can be used to wipe them, and then they can be finished with a brush.

　　Precautions for watch cleaning

　　If you choose general wristwatch cleaning tools, they typically include an old toothbrush and watch-specific detergent. No. 120 aviation petrol is generally used as the cleaning fluid, but since petrol contains a certain amount of impurities, it is best to filter the No. 120 petrol using filter paper to remove impurities before use. Cleaned parts must be air-dried or heat-dried. If necessary, use a brush first to remove dirt from the watch or a willow wood stick to remove sludge, and then place them in clean petrol for cleaning.

　　When carrying out cleaning, the crown of the watch must be fully pushed in and screwed down, and the watch must not be operated during the intermediate process. After cleaning is complete, quickly wipe the watch dry with a soft, dry cloth, and it is best to use the warm air of a hairdryer to quickly dry the watch at an appropriate distance.

　　Dry wiping is certainly not as effective as washing with water. Any dry wiping also requires using a toothpick or matchstick-type item first to remove stubborn stains from the watch surface, and then wiping it. You can use the kind of cloth used for wiping spectacles. The premise for soaking and rinsing a watch with water is that the watch must have reliable water resistance; otherwise, it is not worth getting water inside the watch because of cleaning it.
