What is the error standard of the watch?

      Mechanical watches due to the structural characteristics of the spring, materials, friction and fatigue between the rings, the output torque changes from strong to weak, and the spring and the friction generated by the spring and gear transmission distance, will affect the accuracy of the clock travel time. Further weather temperatures, gravitational forces, magnetic fields, regional environments, and their location also affect the normal operation of the clockwork pendulum clock. Today's quartz watches overcome the weaknesses of mechanical watches and make use of extremely stable high-frequency vibrations of quartz crystals as a benchmark for time. Quartz watch travel time error is generally ± 0.5s (excellent product), mechanical watches travel time error in the ± 15s/d - ± 120s/d range is even greater, to some of the well-known foreign brands watch for example: imported Jazz watches ( Its export standards are men's watch -25 ~ +29s/d, female watch -30 ~ +120s/d, 4 - 5 types such as Pronto, Nivada, Certina ), Enicar, Sandoz, Titus, etc. The general standard for factory and retailers is that the weekly difference is less than ±45s/d, and 2 to 3 types of tables such as plum blossoms ( Titoni, Syma, Marvin, Heuer, etc. are less than +30s/d, upscale, such as Rolex, Omega, and Longines are less than ±15s/d, Imported Japanese watches, men's watches generally do not exceed ± 50s/d, female watches do not exceed ± 60s/d. The above data is for reference only. If you are used to quartz watches, please do not have to be surprised by the high error of the mechanical watch, fish and bear The palm of your hand cannot have both, and many people's mechanical complexes are not quartz watches that can be substituted. Conversely if you are on time High precision requirements, may be selected quartz watch
