I found a picture of the 8500 movement in the planet ocean and compared it to mine. Under the ruby looking piece and balance wheel in the picture there seem to be gold spokes that I'm not able to locate in my movement. Sorry if I'm not using the right terminology.



White and black arrows point to what I'm referring to


And here is my movement


And here's another close up I found online and those gold teeth aren't there either:


Since I bought this watch used two years ago I'm beginning to wonder how genuine the watch is now. It came with all papers and was originally bought from an AD.

Anyone have comments? I took my cellphone flashlight up close and still can't locate these spokes.

 

Do you have an OB nearby? Maybe pop in and just have them authenticate to put your mind at rest.

Your watch is fine -= no need to take to anyone. The serial number indicates it has an 8500 B version inside, which uses a different shape and colour co-axial wheel (the part in question) than the later versions do.

It's all good.

The comparison pic shows an example of a replica 8500 movement. I suspect your movement is genuine..

 

No it doesn't - every photo shown in this thread so far is genuine...

 

Ok.. Maybe I'm wrong. However, the description clearly reads Master Planet Ocean Replica Coaxial movement.

Cheers..

 

The first image appears to be from a site that discusses (at least) fake watches. However what they are showing here is completely correct. I would assume that on fake sites, real watches are shown to gauge how accurate the fakes are in comparison (I don't know because I don't frequent such sites). The top image with the caption you are referring to is a rendering rather than a photo, and I suspect is an image that Omega produced themselves.

Again the movement images shown here are all good. We have seen people post auctions with fake 8500 movements, and they certainly do not look like these. They are faked by putting a plate over the whole movement to hide what's really running the watch. Items are out of place, the balance is not right, there are no pivots in any of the jewels, etc. Faking an 8500 to the level shown here would be a major undertaking that fakers just aren't up to yet.

 

Thanks a lot Archer, you may have saved me some paranoia. So what you're saying is the early versions, when the 8500 first came out, they had this golden spoke cog sort of mechanism and it was taken out in later models such as the one I have?

 

Also, what's the breakdown as far as serial numbers and how they're correlated with the 8500 generation brackets?

 

Other way around - later versions than yours have the gold co-axial wheel.

 

Archer; how about using a camera attachment to a disecting microscope? vinn

 

Interesting. My watch was purchased in 2013 from an AD - this makes it one of the earlier editions of the 8500 movement? Around what year was the new 8500 introduced with the gold co-axial wheel (pictured below with arrows)



And what's the serial number breakdown in regards to knowing which SN would have the updated movement? Just asking since you knew right away mine was an 8500B.

I took a new picture of my movement - you're absolutely sure it's genuine? Sorry, don't mean to beat a dead horse, I just want to put this to rest.



Are you really an Omega qualified watch maker? If so, that's pretty cool! Thanks for your help too.

I also don't even see a coaxial wheel at all, even if it's not gold. Did the older ones like have a different shape coaxial wheel?

 

You bought it from an AD. They would have too much to lose to try selling fakes, @Archer is an Omega certified watchmaker. Listen to what he says.

 

There's a wheel right under the balance wheel of your watch, that's the coaxial wheel. You wouldn't see a wheel, but a pallet fork under the balance wheel of the old style movement.

 

Not quite. I bought it from a guy who bought it used from An AD, papers, receipts and all

 

Gotcha. So that mechanism was done away with with the newer 8500 movements

 

Yes it's an earlier version. The G version has the gold co-axial wheel, and it was released in 2014.

I don't know where the transitions are for the serial number range. The reason I knew what version yours was is because I looked it up on the Omega Extranet - something I have access to because I'm a watchmaker, and is not available to the general public.

Yes.

Yes the shape in the A and B versions is different than the G, so instead of looking like the "ninja star" version, it's more like a regular wheel. This is example not from an 8500 but more closely resembles what your co-axial wheel looks like in overall shape. There are differences because this is a 2500 wheel:



Now I would suggest you relax and enjoy your watch.

Cheers, Al
