Common problem:
1. Ordinary quartz watches daily error of less than one second,
Accuracy is dozens of times than the mechanical watch, quartz watch which is mainly due to high and stable quartz oscillator oscillation frequency.
Mechanical watches because of their structural problems, the Earth by gravity, the horizontal position and vertical position offset will produce potentiometer, winding to relax from the tight, torque imbalance, coupled by the outside temperature, magnetic field, vibration, and other effects All will work with some errors.
International industry standards: mechanical error range of 45 seconds / day superior products, 120 seconds / day for qualified products.
2. just received automatic mechanical watch, it is not working. Do not wear long or does not work, is not it bad?
Automatic watches by kinetic energy to go a long time without wearing will stop, when the 1st wearing manually to 30 laps around the winding, usually not less than eight hours to wear every day, in order to guarantee energy.
