Basic knowledge of watches (II)

Magnetic field have any effect on the watch?
Antimagnetic watch the so-called, in fact, the table is not one hundred percent of the parts can Antimagnetic, only the main parts, such as the balance wheel,high heel, hairspring, wind and other materials used Antimagnetic. So watch for the magnetic field is certainly influential. In particular, quartz watches, quartz watch as to promote micro-pointer is the magnetic force to promote to promote, that is,shoes,dre monster beats, a stepper motor. Encountered a strong external magnetic field, it will stop or speed deviation. Inaccurate quartz watch, most of magnetic materials at play. The solution is very simple, as long as far away from the magnetic field, re can be a good time.
What is the performance of mechanical watches failures and manufacturing defects?
State Bureau of Technical Supervision and other departments on the "liability returns some of the goods" as stipulated in the performance of fault is inconsistent and security products, health requirements, the existence of endangering personal safety, property safety of unreasonable risk, or do not have the product should be the use of performance, or does not match the quality of the situation and express.
For such a time clock apparatus, the performance of fault movement refers to as a result of defective parts and components manufacturing, assembly quality caused by higher take clocks stop, automatic failure, calendar-week calendar is not working properly, rated time, can not be corrected travel time of ultra-poor can not express the quality of the fault.
Defective manufacture of watches, means that the movement, parts specifications and quality standards are inconsistent, incompatible and use requirements, as well as the uneven surface of scale, and other non-use of asymmetric watchcase factors deficiencies. On a row over a spring can be removed: M Table for more than 36 hours; female form that is more than 35 hours in line with national standards.
Continuation of mechanical watches, take the time to reach the number of hours of qualified operators?
Mechanical watches can be spring all over the first row removed: M Table for more than 36 hours; female form that is more than 35 hours in line with national standards.
