Grand Seiko's watch is a top -notch product that combines design and quality that can walk for a long time.Overhaul is indispensable for that.In addition to the necessity of overhaul and the appropriate frequency, let's explain the services conducted by Grand Seiko.
Why is overhaul important?
Regardless of the genre, there are things to do to keep using the items you have as a lifetime.The important thing in the clock is overhaul.
Even if you have heard the word overhaul, many people do not specifically understand what it is.
Let's reorganize why you need overhaul and what kind of work you do.
Overhaul is said to be disassembled in Japanese.Unlike repair, you can think of it as a regular checkup on a watch.
Many parts are included in the clock case.By being assembled precisely, they create regular movements and engrave accurate times.
Nevertheless, various changes occur as watches continue to be used.In addition to the deteriorated internal oil is transmitted in a wide area and dirt, the linked parts may be worn or the deterioration of each part may occur, which can cause failure.
Before the clock causes a problem, it is disassembled to check the inside, and if there is an unsuitable part, adjust it to a good state.Overhaul, not only in luxury watches like Grand Seiko, but also for general watches, is effective and essential to maintain comfortable movements.
How is overhaul doing?Let's explain the general flow.
Before disassembling, first check the appearance and start by checking the operation, waterproof performance, glass and strap scratches, etc.After that, open the case to disassemble the movement and check for any problems in each part.
When an abnormality is found here, adjustment or repair is performed.In addition, if there are parts that are deteriorated or exhausted, it will be replaced.
Even if there is no problem, dirt due to oil etc. can be seen.They will be dropped by a specialized cleaning method using chemicals.
After cleaning, the parts are accurately re -assembled while lubricating, polishing the surface scratches, etc., and the resuscitation case and buckle straps are installed, and proceeding to pass / fail judgment such as appearance and waterproof performance.
Then, it ends after the final confirmation of the mainspring and the date setting and the checking needle operation.

The overhaul is indispensable to make the attached watch last longer, but how often should it be done?Many brands have multiple movements like Grand Seiko.Explain the frequency by type of movement.
Many mechanical watches are considered to be overhaul once every three to five years to maintain a comfortable operation.
If left for a long period of time, for example, the lubricating oil may deteriorate, create a remarkable wear of parts, and may cause a failure.
In addition, aging is inevitable for packing to prevent water from entering the case.If left unattended, it will lead to a decrease in waterproof function.
Therefore, it is important to check each part within the useful period, and it should be performed once every three to five years.
On the other hand, quartz watches are driven using batteries and motors.For this reason, many people think that overhaul like a mechanical clock is not needed.
Certainly, there is no doubt that overhaul is unnecessary for the power part that moves by power supply.However, if it is a quartz watch on an analog display, the movement of the needle is due to gears.
Oil is needed to smooth the gear movement and reduce wear.For such parts, overhaul is also necessary because it deteriorates like a mechanical watch.
However, the interval between the overhaul is less likely to occur even if it is longer than a mechanical watch.It is a good idea to do it about once every four years.
多くのクォーツ時計と異なり、グランドセイコーの9Fクオーツは、職人によって手作業で組み上げられ、高い精度を維持している。ゆえに、クォーツ時計と言えどもオーバーホールは不可欠なのだ。We have mentioned the appropriate frequency of mechanical clocks and quartz watches for each of the overhaul.However, I want to know that the interval differs depending on how you use it.
Depending on the person you wear, the use of the watch varies.Some people always use it for work or private, while others will only wear it on holidays.
The longer you wear, the more environmental changes will occur.Not only dirt adheres, but as the temperature changes, and the number of opportunities to hit the wind and rain increases, the causes of deterioration will increase.
If you feel that the watch has been put on, I want to overhaul the time earlier, regardless of the frequency mentioned above.That leads to long -lasting precious watches.
