Longines watch is a well-known watch brand, which is favored by young people. In the process of using it, some people may encounter the problem of inaccurate date, but they don’t know what to do? Today I will share with you how to adjust the date of a Longines watch.
How to adjust the date of Longines watch accurately
1. If it is a Longines mechanical watch, pull out the first gear to adjust the day and date, and pull out the second gear to adjust the time.
2. First of all, at 24 o’clock, the hands are in the second half circle. Do not adjust the date between 10:00 and 2:00 in the evening, as this may damage the date transmission gear.
3. Then adjust the time from 10 pm to 2 pm first, and then start to dial the knob to adjust the date. For example, if today is the 26th, you need to adjust the date to the 25th, then dial it out, adjust the pointer to make the date jump to the 26th, and then adjust to the correct time.
4. Note that if it is morning, the hour hand is adjusted less than one circle. If it is in the afternoon, you need to turn more than one circle, so that the pointer at 24 o’clock is over half, and you must pay attention to the fact that 24 o’clock must match the actual time.
5. If it is a Longines watch without a calendar, when the second runs to the 12 o’clock position, pull out the crown and turn it clockwise to adjust the time.
6. If the Longines watch has no seconds, for the accuracy of the time, you can adjust the minute hand to the first two minutes before you want to adjust the time, and push back the handle after adjusting the time.
7. If it is a Longines watch with a calendar, pull out the crown a little bit, you can adjust the day clockwise, adjust the date counterclockwise, pull the crown to the outermost, you can adjust the time, the specific operation is the same as that of a watch without a calendar.
What should be paid attention to when adjusting the date of a Longines watch
1. Do not adjust the date between 22 o’clock and 2 o’clock (some watches are between 20 o’clock and 4 o’clock), otherwise it will easily cause damage to the watch and incorrect calendar jump.
2. In order to prolong the service life of the watch, many watches adopt the method of slow jumping, that is, jumping gradually around midnight. Generally, it is normal to complete the jump before 2:00 am, and some watches are completed by 4:00 am.
3. If the calendar jumps during the day, you can adjust it. If you find that the calendar jumps around noon during the day, it is generally because the time of the watch is fast or slow by 12 hours. For example, it is actually 11 o’clock in the morning, but the watch is 11 o’clock in the afternoon the previous day. You only need to dial the hour hand of the watch one more time, that is, change afternoon to morning. And this situation is relatively common, about 50% chance.
4. Generally, watches need to be dialed clockwise when adjusting the time, not counterclockwise. Turning the watch counterclockwise can easily cause deviation of the pointer of the watch (the quartz two-hand type should be turned counterclockwise). It should be paid special attention that if it is worn by the left hand and adjusted by the right hand, the forward rotation is clockwise.
5. Different styles of watches have different adjustment methods, but when adjusting a watch with a calendar function, it is necessary to consider the factors of morning and afternoon.
What is the reason for the inaccurate date of Longines watches
The inaccurate date of Longines watches is generally due to insufficient power, damage to internal components of the movement, or magnetization of the watch. If the date of a Longines watch is inaccurate, you need to open the watch case first to check the internal movement components. After the Longines watch movement is damaged. The date display will be inaccurate. Reverse winding is also an important reason for inaccurate dates, which will affect the normal operation of the watch calendar dial.
