Accuracy of Quartz Watch and Automatic Watch

The term accuracy is used to indicate the accuracy of a watch. As such, a watch with quartz movement reaches a much higher precision than a mechanical watch.
But let's look at the accuracy of the different watches in detail

Precision quartz watches:
Synchronizing quartz watch it is performed by an electronic oscillator. Its frequency is maintained by using quartz crystal accuracy. A watch is more accurate the higher the frequency of the pulse generator used therein. In a quartz watch like Dalas watch or MEGIR 5005 analog watches, with the usual frequency of oscillation, usually a deviation occurs 15 to 30 seconds per month. Because offset errors it adds up over the months, it also has quartz watch to synchronize regularly with that established a more accurate value on the watch.

Precision automatic watches:
Automatic watches are mechanical watches, in which each arm movements are supported by a spring mechanism automatically by a rotor. Most rotor bearings remain in movement in the watchcase due to its inertia and gravity in space, so that a pair is applied to the winding mechanism.

Precision automatic watches depend on several factors. Above all, the way goes to the owner determines how accurate a timer. For an active person who takes the watch also in sports, the automatic movement will react differently than for a person who spends a lot of time in the car or at your desk. Take a cue from user activity, factors such as temperature and air pressure is critical in determining the accuracy of an automated system. Automatic watches very high quality is able to get deviations of less than 6 seconds per day. A normal deviation is usually between 10-30 seconds per day.
