Mechanical watch failure, mechanical watch what to repair

If a mechanical watch needs to be wound manually, so that it has to be operated almost every day, in the process of winding the mainspring, the parts are more stressed, and the wear and tear of the chronometer certification parts is relatively large, and the winding is prone to problems.

1. When the watch handle is twisted, the watch can only dial the needle and cannot be wound, because the clutch rod is not in place, and there is a problem with the handle shaft or pull gear.

2. There is idling and there is no "card card" sound when winding, which may be due to the loosening of the screws of the large and small steel wheels.

3. When winding, there is a strange sound of card and cannot be wound, which is generally caused by the wear of the helical teeth of the lying vertical wheel, or the meshing gap between the vertical wheel and the small steel wheel is too large.

4. When winding, I feel that the force is light, and the string is not satisfied, it is obvious that this is the mainspring is broken, and the mainspring has the most broken tail hook. The watch of the broken tail hook can still move, but when the mainspring is almost full, it will suddenly relax again.

5. For watches that are wound on their hands, Blancpain and Liang Wendao generally have 30 normal windings, which are basically full, and the time to start the winding every day should be in the morning as much as possible.

Hold it in your hand and shake it a few times, and then adjust the time when the second hand turns.

Maintenance method of mechanical watch:

1.If it is a manual mechanical watch, the mechanical watch should be wound regularly, and it is recommended to wind the mechanical watch around 8 pm.

2.Automatic watches, such as insufficient arm movement, need to manually wind the watch, and the rotation of the crown needs to be controlled within 20 turns.

3.An automatic watch that has not been worn for more than 40 hours requires twenty turns of the crown to activate the movement's drive system.

4.Regardless of the water resistance of the watch, it should be avoided as much as possible, and if it does, wipe it dry and make sure that the crown is locked at all times. It is best to replace the waterproof ring once a year.

The most common reason why the watch won't go is because the battery is dead.

It may be that the watch has been bumped before, and there is a problem with the watch movement, which causes the watch to not leave.

Maybe you have been carrying it for too long, and the mechanism may be slackened after a long time, causing the watch to suddenly stop leaving.

Mechanical watches rely on mainspring windings to provide power, and the timekeeping is carried out by means of gearing. Mechanical watches are divided into manual and automatic winding. Due to the complex structure, the phenotype is thicker and heavier.

Because of the characteristics of the principle of time, it is affected by gravity, mechanical friction, temperature changes, usage and other reasons.

The watch has been flooded before, and you may not notice any problems at first, but after a long time, it may lead to some problems, and there are many reasons why the mechanical watch does not go, such as: there are bumps, movement gears are misaligned, the watch is magnetized, and the sludge is dried for a long time, etc., which will cause the mechanical watch to not go.

The watch goes fast, water ingress problems, etc. Watches go fast, mechanical watches are more susceptible to magnetic fields and need to be demagnetized frequently. Water ingress problem, the basic waterproof function of the mechanical watch is poor.

Mechanical watches are comparatively heavier. Store it carefully and flat. Moreover, mechanical watches are more complicated, so you should pay attention when cleaning. Secondly, there is a certain error in the timing of mechanical watches.

Common mechanical watches have problems such as inaccurate time and easy breakage, so the cost of general maintenance is very high.

The watch stops secretly, goes fast or slow, the watch gets into water, accidentally touches the scratches, the watch handle breaks, the dial rusts, the movement does not run, the watch accidentally touches the magnetic field, etc.

The common faults of digital electronic watches are composed of five parts: integrated circuit, quartz **, electronics and case, and the structure is relatively precise. What are the common watch failures during wearing?

The watch battery is out of charge and the watch stops working: at this time, you should replace it with a new battery. The old battery should be removed in time to avoid corrosion of the movement by liquid if left for too long.

The LCD panel of the watch expires and cannot continue to be displayed: the LCD panel will gradually deteriorate during use, resulting in failure. For popular digital watches below 100 yuan, the service life of the LCD panel is about five years, and the service life of the LCD panel of a better digital watch is five to seven years, and it needs to be replaced with a new one when it expires.

Button failure: For better quality digital watches, the buttons generally do not fail, and pressing the wrong button will not damage the performance of the watch. However, in popular digital watches, if you press too hard, the watch buttons will fail.

Battery leakage, causing the watch circuit to be blocked: The battery is not of good quality, or the watch is frozen at high and low temperatures, which will cause the battery to leak. This fluid can corrode the contacts of the power path, causing them to malfunction.

Poor contact or desoldering of component solder joints: With this kind of failure, the watch light will not light up, the button will fail, or the timing will suddenly appear large.

As for the integrated circuit, quartz **, etc., as long as it is a qualified product and has not been violently knocked, the service life of the watch is relatively long.

In an automatic watch with a hand bar, it is advisable to check whether the prime mover mechanism is working normally through the hand bar, and if the pawl is observed bouncing on the large steel wheel teeth and feeling that the roast is being tightened one by one in the process of rotating the upper bar handle, it indicates that the prime mover mechanism is basically normal. When the mainspring is fully wound, although the mainspring slips in the barrel, it is also a normal range, because the mainspring of the automatic watch is different from the mainspring of the ordinary mechanism watch, it has a section of auxiliary spring attached to the main mainspring, and some of the auxiliary springs have an external hook on the inner wall of the barrel wheel and also have an arc monk, as shown in the picture above. Experts pointed out that when the prime mover mechanism of an automatic mechanical watch takes these measures to prevent overload and damage to the mechanism after the mainspring is wound, the automatic mechanism is still on the upper bar.

The mainspring is tightened to a certain extent and slips, which can not only ensure the output torque of the mainspring, but also do not hinder the continuous operation of the automatic mechanism. In automatic watches without a hand-wound mechanism, a screwdriver can be inserted into the screw of the large drum screw, and the mainspring can be rotated to tighten the wind, as if still observing and feeling. In the above two cases, it shows that the prime mover mechanism of the mechanical watch is normal, otherwise the failure of the previous mechanism of the automatic mechanism should be repaired first, and then the automatic mechanism should be repaired.

so as not to repeatedly disassemble the automatic mechanism. Check if the robot is malfunctioning. If the transmission of the automatic mechanism is more flexible, and the pawl bounces on the large steel wheel teeth, it indicates that the automatic mechanism is basically normal.

If when the automatic hammer is rotating, the parts of the manipulator strip mechanism are attached to rotate together, then it means that the disconnection device is faulty, and when the hand is on the strip, the automatic hammer appears to run at high speed, then it indicates that another disconnect device is the automatic strip system disconnect device) is faulty.

Mechanical watches are non-linear, unequal, instantaneous transmissions.

Two gears run on each other, and there is a gap between the teeth, which is generally called 'backlash'.

There is also a 'backlash' between the gear shaft that holds the seconds hand and the teeth that push the wheel that drives it.

The movement of a mechanical watch is not uniform, and the second hand is also 'jumped' in six times in one second. Because the second hand is very long, there is a gap between the teeth due to inertia when it is 'jumping', and the second hand 'stops' at this time. Of course, the wheel that pushes it continues to turn, and once the tooth gap is removed, the second hand 'goes' again.

In order to avoid this, a spring is installed on the second hand shaft to prevent the second hand from 'jumping'.

Your watch is slightly loosened 'a little' because of this spring, but this phenomenon has nothing to do with the running accuracy and running time of the watch, it is just a little uncomfortable visually.

Low-end mechanical watches are generally like this, so you don't have to worry about it!

1. It is easy to be magnetized, resulting in inaccurate time.

2. Sweat and water are harmful to internal devices.

3. External vibration, resulting in ineffective gears.

4. The long-term work of the escapement gear leads to wear.

5. The oil is dry.
