ANTI-MAGNET. cal 83 from 1935

Interesting, never seen before with such a dial.

Nice dial! What makes the watch anti magnetic, does it have an anti magnetic cage?

Kind regards,
Paul

Very cool dial and the sword-shaped hands are quite nice too.

There is no faraday cage in either of these watches and I am not entirely sure how their anti-magnetic, or better magnetic resistance, characteristic is achieved, and to what degree. I assume it is through the materials used in the escapement parts.

Interesting how the bezel is bolder than the one on the left. You have identified its age and will find out more in time. So the case is different and I would imagine has a different model number to the other small sec model. Nice find.

Nice Tony! Very cool and another nice find. You must be pleased!

According to the IWC Archives the watch was sold October 4th 1936 to Nowotny, but there is no reference number.
Does Nowotny ring a bell to anyone?

Thank you for your explanation. I wonder whether there is somebody who knows how the anti magnetic property was achieved: I feel assured that the message on the dial is not a false advertisement. There was no silicium balance spring in those days, it must have been a feature that might be quite common now, thus not mentioned anymore, but special in those days: a bit like the watches that were shock resistant. Is the feature used in this watch the same as used now in most IWC watches without an antimagnetic cage? That would be nice to know, for instance when discussing the current Ingenieurs without such a cage: they might still be protected until a certain level of magnetism.

Kind regards,
Paul

Nice catch! Congrats Clepsydra.

That would be nice to know, for instance when discussing the current Ingenieurs without such a cage: they might still be protected until a certain level of magnetism.

To the best of my knowledge the only Ingenieur without a faraday cage that is amagnetic is the Ref 3508 500,000 A/m with cal. 375. To achieve this level of resistance to magnetization, IWC used lessons learned with cal 3755AM of the the Ref. 3519 BUND.
Those lessons appear to have been forgotten. The recent Ingenieurs without a faraday cage are as amagnetic as any Portofino. The Ingenieur brand has been eviscerated.

Let´s make it a little bit more complicated, Antonio :-)

500.000 A/m => Should be resistent against magnetism.

AMAG => Should not contain any ferromagnetic/paramagnetic material.

That are totally different requirements !

Only some parts of the movements are similar or identical ?!

Lets have a look to the ETA calibre 2892-A2 based movements.

The shape looks similar, but the materials of board, etc. are different, steel and alloy of brass.

BTW many Ing. models have shock absorbers, the 500.00 A/m has none.

Thanks Hebe. It is always better to use precise language.

It´s just, I am still interested in this topic and those watches :-)

And this is the new master of magnetic protection.

It´s aprox. > 1200.000 A/m

I know. I've been seriously tempted, and may eventually cave in. It is a wonderful watch any way you look at it.
I wonder why IWC not only gave up increasing the magnetic resistance of the Ingenieur but actually decided that abandoning its fundamental property was s good idea.

Totally agree.

But IWC has still the master of anti magnetic PWs.

My guess is that it was a choice between two alternatives:
[ul]
[li]a strong anti-magnetic watch that was quite thick;[/li]
[li]a thinner watch without strong anti-magnetic properties.[/li]
[/ul]
Trying to estimate what would sell more, IWC apparently chose the second alternative, thereby reasoning that hardly anybody would be interested in the strong anti-magnetic properties at the expense of a thicker watch.

But instead of guessing, you could ask IWC in January at the SIHH, where quite likely some new pilot's watches will have strong anti-magnetic properties and some will not.

I have a rather thin non-IWC divers watch where the anti-magnetic properties are supplied by a silicon balance spring, thereby giving the opportunity to admire the beautiful movement through a back crystal. I wonder whether IWC could choose this solution in the nearby future. How strong the anti-magnetic properties are I don't know, but quite probably more than enough for my everyday life and my incidental airport visit.

Kind regards,
Paul
