My last watch: planet ocean or new Seamaster 300?

what is it that's so special about master co-axial?

Rather than a part of the inside shielding the movement from being magnetized, OMEGA made all of of the parts out of the shielding; enough so a watch is resistant up to 15,000 gauss. More than any other watch.

Then combine that with the original stats of the 8500 range - dual barrel, giving 60 hour power reserve, co-axial escapement etc and you've got one of the best mass produced movements of the current age.

I wanted to love the new vintage sm300, but I don't. Really the most functional watch in the modern line without riding a wave of sentimentality is the AquaTerra

I agree ree I have the bumble bee second hand aqua terra and I wanted a PO. But I would almost rather have the aqua terra captains watch than buy a PO for the whole master co axial reason

They didn't make the parts out of the same material as the shielding - they made it out of an anti-magnetic material.

but what is the FUNCTIONALITY of anti-magnetism?
what level of magnetism does one encounter that could ruin a watch w/o this property?
obviously, don't walk into an MRI with your watch on, but other than that, are we talking about those big high school physics class magnets, or what? what is the danger that they're trying to make these watches impervious to? i just don't get it...
other than watch lovers geeking out over it (which i DO understand) what is the benefit?

Well I think you have to first have some thought or understanding that there is something between a watch being perfect and "ruined" as you put it. I don't think anyone is claiming stray magnetic fields are going to "ruin" your watch.

Watches get magnetized - I see it often. There are more magnetic fields around us than ever before.

Magnetized watches do not function as well as ones that are not magnetized. Magnetism can cause erratic timekeeping, problems with how chronographs function, etc. Having a watch that is very resistant to magnetic fields eliminates this issue for most people.

And it sells more watches - just like companies that produce watches that are rated for depths that no human has ever gone to...

Sorry I didn't mean to offend you or anything. If you look at this photo of a Seamaster inner cover, it is stuck to the magnet I use to sweep the floor for runaway parts (hey, it happens). So clearly this part is not made of anti-magnetic material, and if it was it would not serve the purpose it was designed for.



The few parts that are different say between an 8500 and the 8508 are described in the technical guides as being made from an "amorphous" material. They don't get any more specific than that. You might be able to find out more on the Omega web site by looking at their marketing materials as they might spell out the specific material there.

Cheers, Al

I think a really simple example of antimagnetic functionality is preventing the scenario I've seen a fair few times on various forums when someone takes their watch off at night and puts it on their nightstand on top of a tablet. Not realising the covers often have extremely powerful rare earth magnets to hold them shut/activate power on/off, very soon their watch is out by minutes a day....

If you use it properly, it won't cause any problems. Use it improperly, and you could magnetize the watch instead of demagnetizing it.
