What is the difference between a mechanical watch and a quartz watch?


assistant
Mechanical watches are not powered by batteries within the individual watch compartments. They are powered by gears and springs that manually need winding, maintenance, and support. This technology was developed in a time period where quartz watch technology did not exist, and as a result, needed a more simplified way of maintaining time. Since mechanical watches do not rely on a battery, they are often -/+ 2 seconds every day and need regular resetting.
