You just bought a mechanical watch. Even though you haven't used it that often, the time isn't displayed correctly... If you've come to this article with this problem, we'll explain the causes of incorrect time on a mechanical watch and how to fix it.
Q: My newly purchased mechanical watch is running slow. What could be the cause?
A: In old mechanical watches, posture affected accuracy.(posture difference error)However, in such cases, simply changing the orientation of the watch when storing it can cause it to lose its accuracy.accuracyYou may be able to get it back.
On the other hand, current mechanical watches have small positional error, so their accuracy does not vary significantly depending on the wearer. Rather, the majority of delays are due to magnetism. Wallet-style smartphone cases, bag clasps, Apple Watch chargers, and other items contain powerful magnets. Bringing a mechanical watch close to these magnets will cause it to become magnetized, reducing its accuracy. Mechanical watch enthusiasts should avoid owning anything with a magnet. Speaking from personal experience, most used mechanical watches for sale are magnetized.
A typical modern watch has a magnetic resistance rating of approximately 4800 A/m (amperes per meter), but this specification is virtually meaningless in the face of today's powerful magnets.
Recommended antimagnetic watches
Manual winding (Cal. 3861). 26 jewels. 21,600 vph. Power reserve approximately 50 hours. Stainless steel case (diameter 42mm, thickness 13.2mm). Water resistant to 50m. Price: 1,232,000 yen (tax included).
If you want to wear a mechanical watch in your daily life without worrying about magnetism, we recommend a magnetically resistant watch. Models that have been certified as Omega's Master Chronometer have a high level of magnetic resistance. In theory, they will not become magnetized even when exposed to magnetic fields of 15,000 gauss (approximately 1,194,000 A/m) or more. Incidentally, a magnetic field of 15,000 gauss is equivalent to the strong magnetic field generated by an MRI. This is truly the ultimate magnetically resistant watch.
Other typical mechanical watches with magnetic resistance include:Baume & Mercier Of"Clifton Baumatic"is 1500 gauss (119,400 A/m),RolexThe Milgauss can withstand magnetic fields up to 1000 gauss (approximately 8 A/m). Generally, if a watch has a magnetic resistance of 8 A/m or more, it will be virtually unaffected in everyday life.
What to do if your watch becomes magnetized
If your watch becomes magnetized, we recommend taking it to a watch shop to have it demagnetized.
