First, from an objective point of view, to understand the accuracy of the table, mechanical watch quartz watch itself is relative to the existence of a certain error, oscillation system (including the escapement system and balance spring balance system) coordination and stability is The main factors that determine their ability to accurately travel.
Second, from external factors, the temperature, magnetic field, the impact of interference is a watch precision travel time factors. The temperature changes the working length of the gossamer, while changing the inertia of the balance wheel can directly affect the timing accuracy; magnetic field for the impact of the watch we must be more familiar with the point, because there are many mechanical steel watch material, such as steel Wheel, escape wheel, etc., so very susceptible to magnetic; impact, is also one of the first to bear the brunt.
Third, the chain is not fully or worn state can not make the watch full release of energy. Because all the tests in the factory before the factory is in accordance with an ideal state of daily life of people tested, including the arm swing, the watch accepted the external environment. If you are sitting in the office all day, can not let the automatic mechanical watch has power, the natural time will not be accurate, it will not fully meet the power reserve time. Wearing too comfortable or too much movement, are not conducive to watch the travel time.
the calendar calendar lattice, due to the grid is divided into two different speed, the first within ± 5 minutes to complete the calendar tab, the second in 3 hours to complete the calendar tab.
3, in case of using a screw-type crown of the watch, not hard pull, please counterclockwise rotation to open the lock of the crown, the adjustment time, the crown clockwise rotation and push into the lock.
