ABOUT MECHANICAL WATCH ERROR

The power of the mechanical watch the energy released from movement clockwork. Manually-wound mechanical watch by rotating the crown around a wound to supplement power; self-winding mechanical watch both the daily arm swinging around a wound kinetic energy through the movement of winding components to supplement power can also be manual winding supplemental power. The larger movement Clockwork output torque is relatively stable due to the movement of different sizes Clockwork size, the mainspring torque stability will affect the mechanical watches go mass. Therefore, the movement of different types(different diameters)  travel time accuracy and other technical indicators were different.

Affected by Earth's gravity, the mechanical table flat or stand up, the travel time error is slightly different. Within 24hours, walking is a normal error in the range of-15~75s/d. Cumulative error increase, affect the timing requirements, guidelines to adjust the time according to the user manual.
