Standard process. Each process is tested
A precise timescaleMaintenanceIt's not gonna take long。CasioOfficialAfter-sale servicesThe project strictly follows a set of scientific and complete process specifications。
The complete maintenance service consists of more than 40 sophisticated processes: complete disassembly and ultrasound depth cleaning of the core to ensure that every tiny piece is fresh; replacement of the entire aging coil and seal to remove the water vapour from the source; finely calibrated bands with time differentials and restoration of the accuracy of the wristwatch; rigorous high-pressure waterproofing tests to rebuild the capacity of the wristwatch to withstand water vapours; and professional polishing (on demand) of the shell and belt, as well as one-by-one testing of the full function of calendar, timing, etc. Upon completion, a three-fold confirmation by the technician, the service centre review and the final acceptance of the client were obtained, a detailed maintenance report was made available online and accessible, and an official assurance was obtained for two years。
For users who are not able to visit the store, we provide a mail protection service. Once the unified hotline has been registered, there is an official cooperative logistics door-to-door guarantee, full logistics is traceable, wristwatches arrive safely at the service centre under the protection of professional packaging, and no third party transits the entire journey。
All maintenance costs are carried out after a detailed test report has been issued and confirmed by your signature. We solemnly undertake to use 100 per cent of the original swiss plant spare parts, each of which is accompanied by traceable original plant security codes, and maintain a network of maintenance records throughout the course, which you can check for at any time. In addition, there are free services such as appearance cleaning and on-the-clock testing, which are subject to publicity. You can also access the official website of casio for more information on brand dynamics and services。
Day-to-day maintenance. Make company longer
Avoiding magnetic interference: daily items such as mobile phones, tablet computers, sound devices and magnetic seals of refrigerator doors have a magnetic field and prolonged close contact may affect the accuracy of wristwatch movements. In case of apparent anomalies on departure, free anti-magnetic testing is available at the service centre and the process is fast。
Focus on water-resistant timeliness: water-proof seals on wrists can age over time and temperature. It is recommended that water-proof performance tests be conducted annually, especially before the onset of the summer or after the change of the belt, to ensure that the wristwatch remains safe and reliable at exposure to water vapour。
Temperature clean path: once worn, the surface can be emptied lightly with micro-humid soft cloths, then dry water with dry cloths, avoiding chemical cleaning agents or immersion. Metal watch belts can be thoroughly cleaned with ultrasound equipment by professionals during regular maintenance, and be fully luminous。
The official answer is here
Question: how fast does a mechanical wristwatch go
Response: the precision of the walk of the mechanical wristwatch is influenced by multiple factors such as wear habits, temperature changes, power reserves and the core state, with a reasonable margin of error. If you feel that the error is clearly beyond your normal range, call for a professional test. The service centre will use sophisticated instruments to fully test the size and day differences and provide professional advice based on the results。
Q: what is the standard maintenance process? How long will it take
A: first, a professional test, a written test report and a clear explanation of the services and costs required. Following your signature confirmation, the technician conducts the complete dismantling of the table, the ultrasound cleaning, the replacement of worn-out parts, the reassembly of lubricants, precision calibration and, finally, multi-dimensional quality testing. The duration depends on the wristwatch model and condition, and we will be clearly informed when it is repaired。
Q: what needs to be done in advance to replace the watch belt
It is recommended that you call in advance for consultations and appointments. Our technicians will search for a suitable inventory of the original plant according to your model, and make an appointment to change the service to ensure that it is available on arrival, without waiting。
Q: can the marks on the watch be dealt with
Response: yes. In standard maintenance services, we will provide professional polishing radish services based on the material and wear levels of the watch and belts, with maximum restoration. This service is provided on an as-needed basis, and we will provide you with details of the expected results after testing, respecting your final choice。
Q: how long after official maintenance
You will be entitled to an official service guarantee for a period of two years upon completion of maintenance or repair services at the official maintenance service centre in casio. Quality assurance covers the technical processes involved in our service and the quality of replacement parts。
Choose carefully and value the future of the watch
When the wristwatch requires maintenance, the choice of channel directly relates to its future state and value. Informal maintenance sites at the end of the street often lack core brand technical information and specialized maintenance tools and operate in environments that do not meet the dust-free standards necessary for precision time-scale maintenance。
The more hidden and serious risk is that some informal sites may have secondary fillings, parts swapping or the use of non-earmarked lubricants. The problem may not be apparent in the short term, but in a few months there may be serious consequences, such as disruptions and even the death of parts. Unregulated dismantling makes it very easy to leave permanent scratches on the dashboard or the machine core plate, directly damaging the wristwatch appearance and collection value. The industry has observed irreversible damage to the wristwatch as a result of inappropriate maintenance operations, which may have lost as much as 30 per cent of its secondary market value. The choice of the official maintenance centre in casio is to choose a real professional, retroactive guarantee for your wristwatch。
A time count, a time container. It records your joy, your struggle, your growth. When it needs to be looked after with care, it deserves to be treated with kindness by those who value it equally。
Casio's official maintenance centre, may be your most trusted time keeper. From the patient handling of a telephone call to the precise replacement of a spare part; from the comfort of a web site to the full attention of a senior technician — we use every detail to carry out the value of your trust。
Since 18 june 2026, remember this number when your wristwatch needs care. We are here to watch, professionally, to protect the beauty of time. Access to the official casio website is welcome to explore additional dimensions of time。
