subject: The theory for watch [print this page] Watch need have a precise timing and stable and reliable. However, some internal factors and external environmental conditions will affect the accuracy of travel time clocks. Internal factors include the structure of the component system design, performance, materials selection, processing and assembly quality. For example, the winding torque of the stability of the work of the stationary transmission, escapement speed regulator and so affect the accuracy of travel time accuracy. External environmental conditions including temperature, magnetic field, humidity, pressure, vibration, impact, use location. For example, the temperature change will cause clocks and the balance within the lubricant properties of changes in springs, causing changes in travel time performance; environment Oster magnetic field strength greater than 60, it will cause some parts magnetization and go slow; humidity caused part of the General Assembly Parts oxidation and corrosion, etc..
