Magnetic field - mechanical watch restricted


If one day out of the earth's magnetic field problems, migratory birds will lose direction, they even do not know is that the movement in the winter or in summer; all of the communications satellite of deviation from the track, relying on magnetic force running traffic Chuxian paralysis; Qihou volatile ... ... This is not sensational, although the "2012" took place in the highly unlikely scenario, but the Maya civilization have anticipated the consequences of it.



Rolex Milgauss created a model for making anti-magnetic technology from the simple "anti-magnetic soft iron sleeve body" to upgrade to the technical level of the "anti-magnetic escapement" research and development.

Omega Speedmaster launched in half a century ago shielded machine watch, it's reputation that the cause of the contribution of human space height of fame.

In the eyes of ordinary wear "shielded" is a special feature, most of the brands produced anti-magnetic sheet magnetic field is only emphasized the danger of the movement.
Pilots watch the pilot series produced by molds ceramic coating case, the selection from the material point of view, it fully into account the problems of traditional magnetic steel case.

"National Geographic" channel of scholars have confirmed that: the earth hundreds of millions of years of life, has been a rare outbreak of sunspots, the magnetic pole shift did occur. In other words, the invasion of the sun, the earth's north and south poles may appear in any place. These are affected by macroeconomic impact on the environment, its occurrence probability is equivalent to children in your own backyard to see the northern lights so low. Magnetic moment for direct human impact is difficult to say clearly, in the natural geomagnetic conditions is very weak, making it difficult for the mechanical movement of the gossamer-sensitive parts such as deformation, the impact on the running accuracy can also be ignored. Unless wearing a watch to magnetite and other magnetic anomalies can feel the magnetic effect for the watch running.

In the watch industry has not developed the 19th century, there were many due to the magnetic field affect the accuracy of the movement which led to serious consequences (the magnetic field produced by the tracks leading to the error when the timer to go, causing a train collision). Before and after World War II, more and more frequent use of electrical appliances, watches, more and more vulnerable to electromagnetic effects. Bear the brunt of a pilot and radio staff, as well as mechanical and electrical engineers, they have a long narrow space close contact with magnetic objects, watch the gossamer ineviwatch occurrence of magnetic phenomena. Electromagnetic fields in modern society are all from the look of the charger to a variety of audio, television, microwave ovens, refrigerators, etc., all have different sizes of electromagnetic radiation. Relatively simple compared to the past, society, today's electronic remote control toys, high-grade leather with a magnetic clasp is a high magnetic field, let alone computers, a mobile phone. Magnetization after the movement gossamer adhesions, resulting in reduced effective radius of bouncing, watch suddenly gone too fast.

Modern life, mechanical watch more and more opportunities for contact with the magnetic field strength is also growing. On their watch itself vulnerable to the impact of the magnetic field must be aware of: first, antique watch with particular attention to anti-magnetic, there is movement assembly antique watchs, their materials are not produced in accordance with modern technology, anti-magnetic properties of weak. Second, the thin sheet can be easily magnetized. As ultra-thin movement space is small, conventional magnetically shielded measures (such as through the thick barrier case to the magnetic field) difficult to implement. Aside the impact on the accuracy of travel time do not talk for a long time will allow watches and movements in the magnetic environment of the injury is not small. High-grade watches with mechanical movements occupy the absolute dominance, if not even running accuracy can be guaranteed, then the only other extra to any function. According to international standards, if the watch in the 4800A / m of magnetic field could continue to run, and test the day after the maximum error is less than 30 seconds shielded standards compliance. Therefore magnetically soft iron shield to protect the mechanical movement is the most simple and effective method, equipped with a magnetically soft iron cover after the movement to resist 80000A / m in the strong magnetic field. Anti-magnetic movement cover increases the thickness, while fine for some attention to the brand, the higher costs they are willing to spend to achieve the anti-magnetic material by improving the results. For example, using their own tailor-made Rolex MILGAUSS containing rare-earth nickel and cobalt blue steel springs Parachrom, combined with little openings sealed magnetically soft iron cover, will be magnetically shielded to upgrade to 100000A / m level.

With modern metallurgy and metal manufacturing technology to improve, watch where he studied under the appearance tab material (magnetically soft iron sleeve) and the various components within the movement area (anti-magnetic alloy of acid, blue steel springs, silicon springs, Cobalt, Nickel and gossamer etc.) are made many improvements. Lange Watch successor - Richard Lange the first beryllium found in nickel steel balance wheel hairspring Improvement. Beryllium metal springs not only reduce the sensitivity of magnetic and temperature, but also can increase the flexibility and hardness of gossamer. In 1930 he published "The Clock gossamer metal alloys," a book in 1931, Reinhard Strausmann Lange received the patent on the basis of its own patents: Non-volatile oxidation-resistant materials. Swatch Empire, the first letter of this material Nicht Variabel und Oxidations bestaendig combined into an acronym Nivarox, which is dominating the world's Nivarox gossamer origin. In fact, if rare public R & D results, the overall lower production costs of the Swiss watch industry, the hottest non-metallic materials shielded silicon is the best material broadly. Physical properties of silicon make it a natural magnetic field did not respond, but its R & D results has just mastered the hands of a few big brands.

Antimagnetic watch has increasing practical value, However, the nations watch Engineer Series, Rolex MILGAUSS this "ultimate Fangci" watch is concerned, far more than the Fangfanrichang magnetic field of the need, they are those who seek the ultimate form fans of "toys."
