我的手錶是116660應該是裝有勞力士自製之防磁游絲,但是我經常以電腦作業,不知我的116660會不會受磁?又如果手錶不小心受到撞擊會不會影響秒差?

分享一下經驗,小弟的是綠水鬼..
去年六月購入,跟藍馬輪流配帶,天天上班使用NB十個小時... 用指南針測試法,並無受磁的狀況發生,秒超也很準.. _________________ SEIKO-->OMEGA-->ROLEX 都是五個英文字的廠牌,所以下一個是PATEK ??? 事實證明,進了ROLEX之後就是一直ROLEX了..... |

ROLEX 應該不會這麼糟吧。
那可能要住在深山戴勞力士才不會受磁了............. 現在到處都是電磁波不是嗎? 相信你的勞力士，他罩的住的。 除非你是什麼電子工程師常處於眾多磁力環境下才需要注意吧（有抗磁錶)。 不知這樣說對否，可請更多前輩做分析。 _________________ 勞心勞力之人士！請配戴勞力士吧！ |

我也有deepsea，同時我手頭上也有Nivarox遊絲的比如EXP，我每天也要用電腦包括桌上型筆記型。。。 我覺得這樣講好了，ROLEX都這麼脆弱的話，那你要那些ETA，甚至那些非瑞士還不如ETA的機械錶怎麼辦。 |

放心 記得有測試過DS的抗磁能力與116400差不多 就算不幸受磁 不就是送錶店而已 
至於撞擊影響方位是可能影響秒差 但是撞擊本身比較可怕吧  _________________ ***八卦山人**** http://3821.org.tw/ |

老哥所言甚是
久久跑趟老王那測ㄧ下就可以了

就如stevehhh老哥所說
撞擊應該比秒差可怕吧！ 現在日常生活中隨時都有電磁波出現 那勞力士就這樣褂了 那其他品牌手錶不就根本不用戴了  _________________ 人生重要的三點... 放開一點-簡單一點-單純一點-集滿三點.就會開心一點 |

好奇請教一下 . . . . ETA有那麼差嗎 . . . . 受磁是游絲問題跟ETA有啥直接關西 _________________ 世界上只有兩件事是公平的 不管你是窮人還是富人 . . . . 你一天都只有24小時 不管你是好人還是壞人 . . . . 你都會有死亡的一天 |

Copied from the internet:
[edit] ISO 764 magnetic resistant watches standard The international standard ISO 764 Horology -- Magnetic resistant watches defines the resistance of watches to magnetic fields. According to ISO 764 or its equivalent DIN 8309 (Deutsche Industrie Norm - German Industry Norm) a watch must resist exposition to a direct current magnetic field of 4,800 A/m (Ampere per meter). The watch must keep its accuracy to +/- 30 seconds/day as measured before the test in order to be acknowledged as a magnetic resistant watch. Annex A of ISO 764 deals with watches designated as magnetic resistant with an additional indication of intensity of a magnetic field exceeding 4,800 A/m. There are two ways of building an anti-magnetic watch: The first way consists in using different alloys, capable to withstand magnetic fields. Such alloys as Invar (iron - nickel - carbon - chromium alloy), Glucydur (beryllium - bronze alloy), Nivarox (iron - nickel - chromium - titanium - beryllium alloy) and Elinvar - an alloy similar to Invar, though less resistant to magnetism and more resistant to thermal influence. Due to different components these alloys have different properties. They were differently used by various watch-making brands. However, since the 1950s Nivarox and Glucydur were extensively used by the watchmakers. Starting with the 60's almost all Swiss watches had Glucydur balance and Nivarox hairsprings. The anchors, escape wheels and other parts of mechanism were also made of non-magnetic metals or alloys. Another way of making a watch non-magnetic is to house the entire movement into a case made of a highly conductive (permeable) material. The movement is covered by an additional soft-iron clasp to prevent the forming of magnetic fields inside the watch itself. (See Faraday Cage.) ____________________________________________________________ Rolex Parachrom Hairspring by J.Peter Tags: Daytona, GMT, hairspring, milguass, parachrom, Rolex, watches, watchmaking It seems there is a lot of mystery surrounding this innovation made by Rolex so I will try and clear it up using two documents of pretty good authority. I wish I could say I had talked to the head of the parachrom department at Rolex but I haven’t. The parachrom hairspring didn’t really start getting attention until a couple of years ago when it started appearing in the new GMT-Master II. It’s distinctive blue color meant that Rolex had to spill the beans about what they had done. I first heard about it when a Rolex representative taught me about it in early 2007. James Dowling (Mr. Rolex) of timezone wrote a nice article about the Parachrom Blu hairspring in August of 2007. — John B. Holbrook, II of the Rolex Reference Page refutes Mr. Dowling’s claim that the parachrom blu hairspring was fitted to all Daytona’s featuring the 4130 movement in his article The Evolution of the Modern Era Rolex Daytona. I am going to take a middle ground. Update October 2008: John has updated his article to conform with the views in this article. The following is from a Rolex communication titled Parachrom Hairspring dated 08/12/06 given to representatives at a factory tour in Geneva: ROLEX has developed and patented a new hairspring called PARACHROM. This hairspring is made of a niobium, zirconium and oxygen alloy. It has been used for the Cosmograph Daytona starting from 2000. In 2005 a blue-coloured version was introduced for the new GMT Master II and the Cosmograph Daytona. It has an even better performance as regards to long-term stability. This blue version has also been patented. The hairspring and balance form an oscillator, the regulating organ of the watch. This oscillator is the guardian of time. The precision of the watch is determined by the regularity of its oscillations. The requirements of this regularity are very great since measuring the time with a precision of 1 second per d ay is like measuring a distance of 1 km to within 1 cm. To guarantee this extreme precision, the torque must be as constant as possible regardless of the temperature to which the watch is submitted. It is for this reason that only a few, very special materials can be used for the hairspring. Commonly used alloys have an iron - nickel - chromium base. These alloys are ferromagnetic and so have two major drawbacks: they make the hairspring susceptible to magnetic fields and to shocks. ROLEX has developed a new family of alloys with a niobium - zirconium - oxygen base know as PARACHROM, which is up to ten times less susceptible to shocks and absolutely unaffected by magnetic fields. The registered name comes form the fact that the alloy is paramagnetic and that it is coloured (CHROM in Greek). This development required 5 years of research by physicists and materials engineers and called for the most advanced observation and analysis techniques. It resulted in the filing of applications for two patents, one for the protection of the chemical composition of the alloy, the other the way of modifying the surface of the hairspring to stabilize its properties (blue colouring). The blue colour of the hairspring increase the prestige of the watch. As a matter of fact, in the history of watch making, bluing a hairspring was an operation done only for the most accurate and sophisticated watches. If the material of the PARACHROM hairspring is very specific, its manufacture necessitates very high technology which is fully mastered in house. . . . In 2005, ROLEX introduced another new feature on the PARACHROM hairspring by modifying the structure of its surface. The layer of oxygen present on the surface is transformed and thickened to about 50-100 nm to increase the long term stability of the oscillator even further. This modification of the surface colours the hairspring in blue (colouring by interference). This innovation has been patented. The hairspring shown in Mr. Holbrook’s article which he says, clearly “is not a Parachrom Bleu but rather a standard Nivarox hairspring” is in fact a Parachrom hairspring from before the color innovation of 2005. You can see a short video from Rolex on the parachrom hairspring at their web page. The parachrom hairspring has been fitted into: All Daytona’s since 2000 (4130 caliber). New versions of the GMT Master II (released in Gold 2005, Rolesor 2006, Steel 2007 Milgauss (2007) Deep Sea Sea Dweller (2008) Day Date II (2008) Gold Submariner with ceramic bezel (2008) Explorer II with 3186 movement (2008) It will eventually be fitted into all models (apparently as they get redesigned) as production allows. |
