For the Mrs

Does anyone know what the differences are between the 8520 and the 8800? Is the 8800 thinner?

Archer

No, the 8800 is not an update or replacement for the 8500 series - again they are completely different movements. Omega uses a number of different movements for different watches. It would be a mistake to look at how Omega does movements by using Rolex as an example. Rolex has a much smaller variety of movements than what Omega (and most other companies that manufacture their own) would have.

Ahh I see. Thanks for the reply. I didn't know and I was able to find very little info on the net about it. Reason I asked if it was a replacement is they are now using it on the Ladies 34mm Aquaterra 150, whereas the last several years they used the 8520. Watch case size and watch line being the same I wondered if it had been replaced. Apparently not. Thank you.

Archer

Omega movement numbering can be a bit confusing...so I'll try to clarify.

When you said "8500 series" to me that means the larger 13 lignes 8500 movement (and it's related movements) used in Planet Oceans, men's AT's, etc.

The 8520 is not part of this family of movements - as noted it is a small movement primarily used in ladies watches. It is still used in many models (for example Constellations) and is not discontinued.

The 8800 is smaller than the 8500, but larger than the 8520 - it is about the same size as the older Cal. 2500 movement.

Cheers, Al

Very nice! I have been looking at the blue dial MOP version of this very watch for my partners upcoming Bday! How does she like it?

I got a Rolex 169622 for my wife for Mother’s Day.
She loves it!

Thank you for clarifying this for me. Now I understand better. It does get a little confusing out there on the web with this stuff. 8520 is an easy jump from 8500 in thinking they are in the same family even though they are not. Good stuff.

Glad to know the 8520 is still out there being produced. From what I have read, it is a robust movement.

Still have a little curiosity as to why Omega would switch from 8520 to 8800 in there ladies 34mm Aqua terra. More of a passing curiosity and not going to lose any sleep over it 😀 Thanks again Archer for your help in understanding the differences.

8520 is a master coaxial, isn’t it?
What do you mean by “still out there?”
Isn’t it one of the newer movements?

Thanks

She loves it- has even sent me wrist shots from work!

Beautiful and feminine yet tough and sporty. Like her

Sorry, I meant that its still being produced. I think it was introduced in 2008 as part of the 8500 series. It was made specifically for smaller watches. From all I can read, its a great movement.

jcmartinez98

I thought the master coaxial movements didn’t arrive until much more recently...that’s what I’m asking...

Archer

There are different versions of the 8520 - not all are the full anti-magnetic versions. Sol the 8520A does not have the 15,000 gauss resistance, but the 8520G does. The full Master Chronometer version was renamed the Cal. 8700.

jcmartinez98

Just out of curiosity, @Archer, do you know if the 8520 G meets the METAS specifications? That is, the dial on my wife’s new watch does say master coaxial chronometer.

Are there versions of these 34mm aqua terras that have the 8700 in them or are somehow different?
