What is the warranty of Longines watches?

Regular maintenance: Your Longines watch, like any other chronometer, must be regularly inspected and maintained. Please bring your watch to a Longines** dealer every two years for inspection.

Water resistance: The water resistance of your watch may be affected by a strong collision, so if you plan to go diving, you should take your Longines watch to a merchant to have its waterproofness checked beforehand. If the case has been opened, the case should be carefully inspected at a merchant.

If the waterproof sealing function of the surface glass and watch proves to be damaged, it should be replaced immediately.

Note for automatic watches: When the automatic winding mechanism in the automatic watch is worn at hand, the watch can be wound by swinging the wrist. If the mainspring is fully charged, the reception will run for approximately 40 hours when not worn. When the watch is stopped, you can also wind it by turning the handle by hand.

Quartz watches: Quartz watches need to use batteries, which can last an average of 12 to 18 months. If your watch has a Battery Life Display (EOL) function, the second hand will only jump every 4 seconds when the battery is almost depleted.

If this happens, you should replace the battery immediately. Failure to replace the battery within the time limit may cause damage to the mechanism.

Best Guarantee: In order to ensure the correct operation of your Longines watch, you must regularly visit a Longines dealer for inspection, repair and service.

The most important thing in watch maintenance is to wash the oil, why wash the oil? Mainly because the gears in the watch movement have been running for a long time, and the movement oil and dust inside have formed some dirt, which is more and more, which will seriously affect the normal operation of the watch, so washing the oil is particularly important. After washing the oil, replace it with a new gear oil, and the watch will run back to normal.

The second step is to adjust the movement, some friends may have said, what can be adjusted to the movement? What I want to tell you here is: the movement must be adjusted, the movement must be reinstalled after washing the oil, at this time it is necessary to adjust the timing error, polarization, etc., all need to be recalibrated, this step is very important, otherwise the watch may not be accurate!

The third and final step is very simple, which is to replace the aging waterproof ring. I feel that this step seems to be useless, but it is actually very important, if the waterproof ring is aged, it will be easy to enter water and dust, causing problems with the watch.

It is serviced every three to five years, but the frequency of watch maintenance is also related to the climatic conditions and the daily maintenance of the wearer.

If the watch is worn frequently and is not usually maintained, then it may be maintained more frequently. It is recommended to maintain the appearance of the watch once a year and test the water resistance of the watch.

Precautions. After one year, it must be replaced with a new waterproof ring, otherwise it will no longer have the function of waterproofing.

Collision avoidance, if the economy allows, it is advisable to wear a mechanical watch when static activities.

If you wear it every day, it's best to tighten the mainspring every two weeks to keep the gears running smoothly and gently rotate the crown until you can feel a slight pressure.

3-4 years. 01. How often should Longines mechanical watches be maintained?

Longines mechanical watches generally operate 24 hours a day, seven days a week. Therefore, the frequency of maintenance of a Longines mechanical watch depends on the type of watch, the climate and the maintenance status of the Longines mechanical watch wearer. Generally speaking, like other precision mechanical tools, Longines mechanical watches should be serviced at least every 4-5 years to ensure the reliability and accuracy of the watch, but also to prolong the service life of Longines mechanical watches.

02. Longines Magnificent Watch 2 3 years to be maintained.

This is indicated on the instructions and is relatively accurate. In addition, the maintenance method is divided into two types: partial maintenance and comprehensive maintenance, if you do not understand something, you can log on to the official website of Longines to inquire.

In general, the frequency of maintenance of a watch depends on the type of watch, the climate and the wearer's daily wear.

If the watch gets water, you can wrap the watch tightly with several layers of toilet paper or moisture-absorbing flannel, place it 15 meters near a 40-watt light bulb, and bake it for 30 minutes to eliminate the moisture in the watch. In addition, you can wear the dial inwards and the case outwards on your wrist to eliminate the moisture after about two hours. If the water ingress is severe, it is best to immediately send it to the watch shop to wipe the oil and clean the moisture on the movement to avoid rust on the parts.

As a general rule, as with other precision mechanical tools, the watch should be serviced at least every 2-3 years to ensure its reliability and accuracy.

The frequency of maintenance of a watch in real life depends on the type of watch, the climate and the condition of the wearer.

Professional maintenance content:

The mechanical watch movement is completely disassembled, cleaned, oiled, reassembled, adjusted, and functionally checked, and any worn or faulty movement components are repaired or replaced.

It is best to go back to your "mother's house" every year to check whether there is any improper use or water ingress. In particular, the local climate is humid and hot, sweat, rain and dirty air have accumulated for many years, causing slow erosion to machinery, and the frequency and degree of damage are much higher than those in Europe, America and Japan, so regular inspection is very important; Then it needs to be thoroughly cleaned and maintained every three years.

Common sense of maintenance in sunrise life:

1.When wearing a watch, the sweat on your hands is corrosive to the case, and the case should be wiped frequently with a soft cloth. When not wearing the watch, the plastic holder should be inserted.

2.Do not open the back cover of the watch at will, so as not to dust into the movement and affect the normal operation of the watch, if there is such an operation during the warranty period, it will affect the warranty service that you should enjoy at the special maintenance point.

3.Do not leave the watch in a closet with mothballs to avoid deterioration of the watch oil.

4.Do not put the watch on mobile phones, stereos, TVs and other devices with strong magnetic fields, so as not to be affected by magnetization.

5.Watches that have been stored for a long time without wearing should be wound regularly once a month; The parts will not be in a static state for a long time, so as to ensure the operation and lubrication of the movement in the watch.

6.Ordinary mechanical watches are damp, you can use dry cotton to press on the watch, and then bake with an electric light bulb for 5 minutes, and the moisture in the watch can be completely evaporated. For watches that are severely damp, the time of moisture absorption can be appropriately extended.

7.When sleeping, do not wear a watch, especially a luminous watch, which has a certain amount of radium radiation, and must be taken off before going to bed.

8.Do not adjust the time between 9 p.m. and 4 a.m., as this can easily cause damage to the watch and incorrect calendar jumping. In addition, the watch needs to be dialed clockwise when the time is adjusted, not counterclockwise, and the counterclockwise dial of the watch is easy to cause the deviation of the watch hand pointing (quartz two-hand type should be dialed counterclockwise).

At the same time, it also affects the accuracy of the watch.

9 Pay attention to the waterproof type of the watch you are wearing, do not enter the water, and do not wear the watch to the sauna. Even if it is a diver's watch, if the closed ring is aged, it will still seep water.10Keep the watch box, which can give the watch the safest protection when you don't wear it.
