I own two Omegas, one from 1944 ( Teddington) and a Seamaster from 1964. Do all Omegas are antimagnetic? Where can I find more technical data?
Thank you!

 

The 1944 Teddington could possibly be anti-magnetic, though the movement/case would need to be checked. The 1964 Seamaster would definitely be. Not all Omegas were antimagnetic, particularly models from the early 30s and previous to this.

 

Resistance to magnetism doesn't have to come from just the movement, but can also come from the case in the form of shielding. This shielding doesn't even have to be an inner anti-magnetic cover - it can come from simply adding distance between the movement and case back, since the strength of a magnetic field increases dramatically as the magnet gets closer to an object.

Many older vintage watches used blued steel balance springs, which are easily magnetized. Later alloy springs had greater resistance to magnetism, and the silicon springs basically are not affected. The latest and greatest Omega movements can still be magnetized, but the parts that can still be magnetized are not going to have much of an impact on the ability to run, or on timekeeping.

Thank you for your kind explanation!

 

Thank you so much!!

 

Does anyone of you guys know if it makes sense/is necessary to demagnetize vintage watches from time to time ? I wear my constellations daily and our world is full of magnetizing devices, passenger controls at airports, inductive kitchen devices, electric doo openers, mobile phones etc. Is a demagnetizing service part of todays watch service procedures ? Thanks as usual for all answers. Saluti Stefan

 

If your watch looks like this worry




Read this thread @Archer and @Canuck being watchmakers have some great input

Yes, demagnetizing is most certainly part of a standard service for a mechanical watch. There are more magnetic fields around us than ever before, so if you have symptoms of a magnetized watch, then demagnetizing is the first step. If done properly it’s non-invasive and won’t damage anything.
