What's the difference between a quartz watch and a mechanical watch?

In terms of time accuracy, due to the precision and complexity of mechanical watch structure, it is easy to be affected by environment, temperature and parts wear, which reduces the time accuracy. In general, there may be an error of 15 ~ 30 seconds every day, and a high-quality movement may also have 1 ~ 5 seconds. Quartz watches, on the other hand, can maintain high accuracy because of the stable pulse wave provided by the internal time crystal, so generally speaking, the daily error is less than 0.5 seconds, and the monthly error is about 15 ~ 25 seconds. Top quartz watches can even achieve an annual difference of less than 5 seconds.

2. Power supply

The accurate relative condition of quartz watch is that the battery must be replaced regularly. Generally, the service life of batteries is 2 ~ 3 years, and the service life of lithium batteries is longer, which can be used for 7 ~ 8 years. Mechanical watches don't have to worry about battery problems for life, just wind them regularly, and even self-winding watches can be worn often to maintain power.

3. Maintenance and repair

The timely oscillation in the movement of quartz watch often gradually declines after 5~8 years of use, which leads to the decrease of travel time accuracy, so it is usually necessary to replace the movement. Mechanical watches can extend the service life of watches through regular maintenance and oil washing.
