A newcomer guide to the boring part: the everyday habits that decide whether a rep keeps running well. It isn’t about QC or which factory, but about what you do with the watch after it arrives. Four areas: **magnets** , **knocks** , **the crown** and **storage**. Corrections and additions welcome; the summary at the end will be updated from the replies.

**1. Magnets**  
The most common “the watch is broken” story that turns out not to be. One owner said the watch was fine before shipping and arrived running about two hours fast a day. An app showed it was magnetized. A magnetized hairspring sticks to itself, and the watch suddenly runs very fast. Typical sources: magnetic phone cases and mounts, tablet covers, laptop lids, speakers, magnetic bag clasps. Someone even asked about the magnets in a folding phone.

**2. Knocks**  
A mechanical movement doesn’t like sharp impacts. Door frames, desk edges, a drop onto a hard floor. Most reps survive the odd bump, but a hard knock can shift the regulation or worse.

**3. The crown**  
Screw-down crowns: always screw them back down, gently, and never operate the crown while the watch is on your wrist, which bends the stem at an angle.

**4. Storage**  
Dry, away from magnets and away from direct sun.

Helpful. How do you tell whether a watch is magnetized without an app?

The app is the easy check: a timing app that listens to the watch will show a gain of minutes per day. Without one, the old trick is a compass: hold it next to the watch, and if the needle moves as you move the watch, it’s magnetized. The good news: demagnetizing is quick and doesn’t open the watch. A small demagnetizer does it in seconds, and many watchmakers do it on the spot.

On “are any reps anti-magnetic?”: a reasonable assumption is no, unless proven. Someone asked whether a rep Milgauss has the soft-iron shield of the genuine one, and suspected it doesn’t. Even a model whose genuine version is built to resist magnetism shouldn’t be trusted to on a rep.

And the opposite case matters too: not every fast-running watch is magnetized. One owner of a 3130-type watch running about +25 to +30 seconds a day checked for magnetization first and found none. That’s regulation, a different problem. So: check for magnetism first, because it’s quick and free to fix; if it isn’t that, it’s a regulation question.

What about watch winders? I’ve read they can magnetize a watch.

That question comes up in several threads. A winder has a small motor, and a magnet in it is a possible source, but in most reports the watch was fine. If a watch runs fast after a while on a winder, check for magnetism before blaming the movement. And a winder isn’t necessary: letting an automatic stop and restarting it is fine.

On storage, one small thing: a newly arrived crystal attracting dust, “a dust magnet”, is usually static or a fingerprint film, not a defect. Clean it as in the [cleaning thread](https://superreps.net/t/pulizia-di-bracciale-e-vetro-cosa-usa-la-community-e-cosa-e-ancora-da-verificare/20). Water is its own topic: [Swimming with a rep diver](https://superreps.net/t/swimming-with-a-rep-diver-does-pressure-tested-actually-mean-its-safe-in-the-water/101) explains why “pressure tested” isn’t the same as safe.

And on knocks, a warning from an owner review that was updated after some months: the movement had come loose inside the case. That’s not something habits can prevent if it’s a build issue, but it’s a reason to note how a watch behaves after a knock. If it suddenly runs differently, or you hear something loose, stop wearing it. When a service makes sense is in [the servicing thread](https://superreps.net/t/revision-bei-replik-uhren-wann-ist-sie-sinnvoll-und-wann-tauscht-man-lieber-das-werk/130).

</div>

Everyday habits, in short:

1. **Magnets:** keep the watch away from magnetic phone cases, tablet covers, laptop lids, speakers and bag clasps. If it suddenly runs minutes fast, check for magnetism first. Demagnetizing takes seconds.
2. **Not every fast watch is magnetized:** if the check is negative, it’s regulation.
3. **Assume no anti-magnetic protection** on a rep, even of an anti-magnetic model.
4. **Knocks:** avoid hard impacts. If it runs differently after one, or something sounds loose, stop wearing it.
5. **Crown:** screw it back down gently; never operate it on the wrist.
6. **Winders:** optional. If it runs fast after one, check for magnetism.
7. **Storage:** dry, away from magnets and direct sun.

Clear. Magnetic phone cases are the first thing to keep away from the watch.
