In general, the watch is placed in two situations: one is to replace the crown, and the other is to replace the crown with the lever. The first one is often caused by the back of the crown or due to rust, or due to external force and the resulting breakage, the second case is more complicated.
Generally speaking, it is caused by the tail hook of the internal movement of the watch being disengaged or unable to lock the handle. The causes of failure include the wear of the splint, the wear of the tail hook, and the loosening of the screw, and the deformation and injury of the crown. Early watches were generally caused by loose screws
Because the crown of the watch is easily damaged, after a long period of use, the waterproof rubber ring inside the crown will age. If the seal is not good, it will go directly to the position of the crown. The root of a corroded crown bar will become thinner and its strength will decrease accordingly. The most common “mother and mother” crowns in Rome and Mido are the two-piece crowns for the molecular and mother studs, because they are totally elastically matched, and if they are corroded, the elasticity will decrease, so they are easily affected by Pull out.
If you find that the crown has fallen off, you should keep it properly and don’t lose it, and then send it to a professional repair shop for repair in time. It is best not to repair it by yourself, not to repeatedly insert or pull it out, which will add a lot to future maintenancetrouble.
When pulling out the watch, we must use lighter force, because the parts of the watch are very small and thin, it can be said that our original watch will be pulled out if it is hard to get it, especially for thin pay attention.
If any abnormalities occur in Cartier watches, they should be sent to the nearest Cartier designated outlet for inspection immediately.
The fully automatic mechanical watch must be worn for more than 10 hours a day when the amount of activity is sufficient for normal operation.
Different watches should be worn on different occasions. For example, it is best to choose sports watches with excellent waterproof and shock resistance during sports.
If there is a watch marked “WATER RESESTENT” or “3ATM” on the watch cover of Cartier watch, it is generally only applicable to water splash or light rain under no pressure.
If you want to extend the service life of Cartier watch leather straps, you should pay attention to avoid contact with water as much as possible. If you accidentally get wet, you should wait for it to dry before wearing to prevent odor.
We try to develop the habit of not wearing a watch to sleep, so that the leather watch can have a chance to wheeze.
In winter, the leather strap of Cartier watches is easy to harden and will have a curved shape. At this time, be careful not to fold the leather strap in the opposite direction to avoid damage to it.
Specially remind everyone that any watch should not be worn in warm water or in the bathroom, even if your watch is a waterproof watch, because the watch’s sealing roll is rubber, it is easy to aging when heated, and the surrounding water vapor molecules are relatively small, and it is easy to penetrate into the watch Shell, causing damage to internal machinery.
Because the internal mechanical structure of each watch is different, under normal use, the error of a mechanical watch or a mechanical automatic watch is within 30 seconds per day (the sub-standard is issued by the national ministries and commissions), and the quartz watch The lower error is more accurate.
