Citizen relies on its own technical advantages in precision machining, measurement technology, energy saving and manufacturing technology, and combines exquisite design to continuously develop wrist watch products that perfectly reflect the integration of technology and beauty.
Citizen mechanical watch is driven by clockwork and controlled by balance wheel speed regulation system. Its travel time accuracy is influenced by many internal and external factors.
The higher the frequency of the oscillator, the more stable the oscillation, the stronger the anti-interference ability, and the more accurate the watch will be. The oscillation frequency of Citizen mechanical watches is 6Hz/S or 8Hz/S (ordinary mechanical watches are limited by their principles, and the oscillation frequency is generally between 5 ~ 10 Hz/s). In addition, the full chord or half chord of the spring, oscillation or vibration caused by external force, etc. It will also affect the time accuracy of mechanical watches.
The advantage of Citizen's mechanical watch is that it can be used for a long time after regular maintenance and oil washing. The disadvantage is that the error is larger than that of quartz watch, which is caused by the quality of production and the easy influence of gravity on the movement in the watch. Usually, the error of mechanical watches is calculated by how many seconds are different every day, while the error of quartz watches is calculated by how many seconds are different every month.

Brand culture
Citizen has been adhering to the concept of multiculturalism and persistently pursuing Excellence and innovation. As one of the citizens of the world, citizens have the responsibility to use technology to promote the positive development and continuous evolution of world culture. Citizen regards it as its own responsibility and will unswervingly meet all opportunities and challenges in the future.
As a professional comprehensive watch manufacturer, Citizen's watchmaking process covers all the processes from the manufacture of individual parts to the final assembly of watches. Citizen makes watches in a craftsman-like way, constantly expanding the technical boundary and exploring new possibilities with our rich experience.
Looking back on the 84-year history, Citizen has repeatedly set a precedent. Citizen took the lead in developing radio wave technology, satellite timing technology and revolutionary light kinetic energy technology. As early as 1976, Citizen took the lead in developing this innovative technology in the industry. This extraordinary innovative technology uses the electric energy converted from any visible light source to completely change the way the watch is driven.
Photodynamic watches do not need to change batteries frequently, which is especially convenient for those areas where batteries cannot be obtained in time. This enables citizens of every country to freely experience the fun of wearing and using citizen watches, leaving an unforgettable memory of time.
