Magnetized?
I have a brand new watch, maybe 2-3 weeks old. I noticed it seemed to be a bit slow, so I measured it a couple of times and turns out it was 15 sec slow per day. Everything else seemed ok, so I just figured it needed to be regulated. Called the Mfg looking for an AD or SC near by and they just had me send it to them - they provided the box and label. They have had it just over a week and called me today and said it was just magnetized and is now running within spec. Suppose to ship back tomorrow.
I have always been under the impression that a magnetized movement will run faster, not slower. Are both possible? How does that work? |

Magnetized is typically fast.

I agree - magnetized watches run fast.

What Watch was it thats giving you problems ?
Many of the modern watches have silicone springs etc to stop watches from getting magnetised or showing the effects at least.

Your watch should have a Glucydur balance.
I have copied below some text on Glucydur Glucydur is an alloy of beryllium and bronze (aka beryllium copper aka BeCu or CuBe on the periodic table of elements) used for balance wheels. The alloy is known for its resistance to thermal expansion, non-magnetic properties and resistance to corrosion. Your watch should not be that magnetised unless you have been going to places that others dare not go ... Do you cook much at home ? Do you have an Induction Hob ? They are known to magnetise watches (and play havoc with heart pacemakers !)

So, given this statement The alloy is known for its resistance to thermal expansion, non-magnetic properties and resistance to corrosion. and as others have mentions magnetized watches run fast - What gives? ![]() |

Obvi I don’t know much about the sitch but what I can say is these companies just fix (Often times botch the attempt a few times) then send back with little to no information.
If it’s no longer 15 secs slow then slap it on and enjoy I’d say. Or sell if the not knowing part hurts which I also get and have been guilty of. |

I have had magnetised watches before (Usually my fault !) and they have not just run slow or fast for that matter. I have found magnetised watches can have "A mind of their own" and run fast or slow and change daily .. No known or perceivable logic at all. There are reports on the web about the P.5000 caliber being unreliable and needing regulation straight out of the box (aka New) and once regulated they are fine. The unreliability in these cases are nothing to do with magnetism but just poor quality control during manufacture. Your AD may say its magnetised but did he check for magnetism and if so he would have been able to tell you precisely what parts are magnetised and what parts are not.

Thanks for the input. I am dealing straight with the Mfg, no AD. They did not say which parts were magnetized, but maybe I can call back and find out. |

Magnetized?
Magnetized?
![]() Can you post your machine results before you sent the watch in and after you received it back? What was the beat setting on your machine and how did you choose it? Did you select the beats offered by the machine or did you dial the numbers? |

I did just set the machine to auto, set the amp to 50 and went with that. I still find slow from magnetized odd. I also find it odd that a brand new watch that had a total travel radius of about 12 ft, once I got it, could be magnetized. The only possible explanation is it came to me that way, or in transit. All just odd. |

I think it was most likely a QC issue such as debris in the movement or a loosened screw or some such issue, or perhaps some impact during shipping, but it’s easier for the manufacture to just stay “magnetism” then to admit to a potential QC issue.

Magnetized?
As you did not post the machine results before you sent the watch back, I would like to see what the amplitudes and rates are (before/after).

- How did they measure (what instrument) that the watch was magnetized. - What demagnetizer (instrument) they are using. - How much (in microTesla) was the magnetisation they measured. Maybe they always demagnetize incoming watches first, by default, and then measure? More likely, your watch was very poorly regulated, which would be their fault, not yours. Finally, I have measured one particular watch that was definitely magnetized when the owner approached a very strong magnet. Below I share my machine results before/after our attempts to demagnetize the watch (with a very cheap blue instrument, not recommended) and the results (with the same setup) after this movement was serviced by the brand. Personally, I have never seen or measured a magnetized watch with negative rates. Regarding post #14, I think you are right about the QC aspect, but I would doubt a loosened screw or debris inside the movement as this would significantly affect measured caliber amplitudes. ![]() |

Watch is back. I give them(PAN) credit, shipped out 8/8, back to me 8/27. All I had asked for was for them to regulate the watch. The reported defect was that the watch was magnetized. The service receipt in the shipping box just states "function check," which is not really surprising.
Before sending in I was -13.32@ 0Hr, and -9.6 @ 24Hr. Again, all I really wanted was to see if they could tighten that up a bit. After service return I am -5.1@ 0Hr and -5.06@ 24Hr. Not bad, not great, definitely different. This just doesn't "feel" like a magnetized situation to me. |

Did you ask them the questions I listed above?

It might be interesting to fully wind it & time-graph it when fully wound, then on days 2,4,6, & 8. I think a single mainspring of this size (8 days) would more typically run on the "+" extreme side of the regulation when fully wound and should typically slow down and run on the "-" side as the mainspring uncoils, but would be interesting to see- if you are so inclined.
