Extended data:

The difference between mechanical watch and quartz watch

The advantages of quartz watch are punctuality (annual error is within ten seconds), small size and thickness, novel style and low price, which is more suitable for fashionable young people; The disadvantage is that the battery needs to be replaced regularly (six months to one or two years).

Mechanical watches have errors (ranging from a few seconds to twenty or thirty seconds every day), are relatively large and thick, and need to be worn on them regularly (some watches can also provide kinetic energy every day), and the price is relatively expensive (most famous watches in the world are mechanical watches), which is more suitable for nostalgic people.
