Non-“Master” chronometer: how antimagnetic?

Archer · Sep 9, 2024

Resurrecting an old thread with a new question - how antimagnetic is the caliber 1863? Exposed behind a transparent caseback, there is not much material left to shield the caliper. How "dangerous" is it to have it while typing on a laptop? I know the discussion on grass cutting, but please keep it serious here.

Depends on where the magnets in the laptop are, how strong they are, and how close you are to them while typing.

I suppose the magnets are in the speakers, close to the monitor, so I obviously keep some distance while typing. But am I the only one to care?

However, just like the laptop manufacturer does not specify the intensity of the magnetic field generated during operation, the watch producers do not comment on the magnetic resistance of watches. Apart from Omega and a few Tudors lately. Maybe I am just overthinking it.

Many laptops have magnets on either side of the track pad & lid as well. Not just the speakers. 👍

If you’re really concerned, you can always take your watch off while using your laptop.

No one here can speak for everyone, but I use my laptop all the time while wearing my 1861 Speedy and have never had an issue. I even had a sapphire caseback on it for the better part of a year.

If you want to know where the magnets are, get some magnetic viewer film...cheap off Amazon...

Lay it over the item in question, and you will see the outlines of the magnets...

The part that will cause the most issues when magnetized will be the balance spring. Modern watches, even before silicon balance springs, are generally made from a material that is quite resistant to magnetic fields. Not impervious, but quite resistant. Magnetic field strength varies with the cube of the distance, so proximity is very important. If you locate the magnets and they are not right next to the watch, you are probably fine.

If the watch does get magnetized, it will most likely run fast, so if you see a sudden large gain in time, then demagnetizing it is simple to do with the appropriate unit.

Wasn't aware of that, thanks for pointing it out.

Thanks a lot, I will try it out of curiosity.

"Can I swim with my Speedmaster?"

"Can I mowe the lawn wearing a speedy?"

The latest one:

" Can I use a computer wearing a Speedmaster"

Dear Omega could you guys PLEASE make a Speedy that may be used on earth? In normal everyday conditiones, you know gravity, dampness and magnets and all that? PLEASE PLEASE.

Yeah, I was afraid someone would pick it up and compare it to the famous topics. Nonetheless, I consider my question valid. Considering that the caliber 1863 is just a rhodium-plated 861 with an extra jewel, this takes us to 1968 (according to Moonwatch only book), when the caliber 861 was first introduced. And I bet that by that time, the people were not surrounded by all sorts of electronic gadgets as we are today. And Archer's answer proves that it might be worth checking for the magnetic field of your laptop.

When I want peace of mind, I get the Metas certified watches and don't bother. But I may be more protective when I call their granddad to duty.

Do this all the time with my 1863. IPad, phone, computer, pretty much anything I would do daily with no consideration for whether or not it would magnetize the watch. Haven't screwed with its time settings for probably two weeks and it's currently 20 seconds fast, so still consistently running a couple seconds a day fast.

You probably don't need to worry about it!

I had my Bremont Alt-p2 Lancaster on yesterday and after an hour or so it'd gained 90 seconds.
The only thing I can think of that may have caused the problem was the bus pass scanner than I used ??

The only other watches that've been magnetised were also Bremonts.
One of these fell victim to a Tablet cover.

To find the magnets on my laptop I just take a paperclip and move it around the case. It will be drawn to the magnets if there is one (or more).
