Master coaxial query

[rokosh]

Master coaxial or just coaxial- what's the difference?
The top-of-the-line PO has Coaxial on it's dial, the new Seamaster has Master Coaxial

[Cuts33]

Master co-axial is antimagnetic to 15,000 gauss.

The co-axial is not, although it does have a non magnetic hairspring and some resistance to magnetism, just not to the extent of the master line.

Are you sure? Even the 15,000 gauss has only "co-axial" on the dial.

He is right. The 15,000 was the first to use the movement and it was still called co-axial. That movement is now in most aqua terras and is labeled as master co-axial. It is the same movement as the gauss...just with a new name to it. It distinguishes older AT models with the newer ones.

My understanding of it anyways.

The "bumblebee" AT is the only one called "Co-Axial" buy yet still has the 15000 gauss magnetic resistance. It says on the dial >15000 Gauss and the caliber is 8508.

It is the only watch with the 8508 caliber.

For whatever reason, they did away with the 8508 caliber and went back to calling it the 8500, but added "master" to the title.

So, 8508 caliber in the bumblee is the same as the master co-axial 8500 movement.

The co-axial 8500 movement that remains in the PO still is not fully anti magnetic.

I've been told by several Omega boutique employees that by the end of 2016 all Omegas with in-house movements will have the >15k anti-magnetic movements. They didn't mention that they would be called master coaxial, though. I'll be courious to see how that plays out. A new reference number or just a new label.

They just came up with the "master" label so I too will be interested to see if they abandon it eventually.

For all the people, money and resources Omega and Swatch have, to this day I cannot figure out 1) who came up with the "master' designation and 2) who approved it.

Introducing the all new Seamaster Aqua Terra Master Co-Axial. Talk about a mouthful.

Bad marketing if you ask me.

If that's a mouthful of bad marketing, what's the Oyster Perpetual Yacht-Master II Superlative Chronometer? :P I think watch naming in general is a little excessive.

Yes, you're right; was looking at the Omega Lifetime magazine this morning- the issue with Carlsen on the cover. Yup, in an article on the co-axial movement, they state very clearly that the prefix Master refers to those movements that can withstand 15k gauss .
And to illustrate this, they have a pic of the bumblebee- without the prefix!

Strange are the ways of Omega

Master is the > 15 loads of articles on it. Useful if you work with MRI machines, speakers or or other situations that put you close to magnetism

I've had a few watches get magnetized. They were not Omegas.

My PO 8500 has never had an issue though. The one thing I've never seen a definitive answer on is the actual resistance in gauss of the regular 8500s with the Si14 balance spring.

Also fwiw, Patek has a whole video on their website devoted to magnetism issues in the service section. So obviously Omega is not alone in seeing this as an issue.
