How can I differentiate a gen ETA 6497 from an CN copy?
- Thread starter togokm

Look at the spoke of balance wheel. There are too many versions of 6497. ETA and Asian. Some even are hybrid of the two.
Under the balance wheel with the naked eyes, you can see the logo of ETA and the engrave 6497-1. It is easy to see when the wheel stop. There is also the photo of this in the accesories section in Andrew web site. He sells the serie E movement. One of the photos clearly shows that, I remember.
The ETA coppies are marked with the ETA symbol too. Look at the balance wheel. The asian coppies were coppies of the 6497-2. The balance wheel is differnt then the stock 6497-1. The swiss ETA the balance wheel. The spokes on the balance wheel tapper smaller , or tapper in as they get closer to the edge of the wheel. The Asian coppies. get wider as they go tward the outer ring of the balance wheel.
i am not sure if you know what you are talking about....look at the pic i post....a gen Pam 232...movement
OP XII, it proves that its not true what you say.....

On Trusty's site, in the Panerai section, he lists a Pam Engraved Bridge Swiss Unitas movement for sale that has the wider spokes at the edge of the balance wheel. Link is here:

He says that this is the best movement ever made and is 98% close to gen.

From what I gather from you guys, seems like the things to look out for are:
1) ETA stamp below the balance wheel,
2) Spokes of the balance wheel.
My concern is really how "swiss" are the so called Swiss 6497 that we purchase?
Comparing the two movements shown below (stock swiss unitas 6497 on the left and a swiss unitas 6497 from PAM reps on the right), the balance wheels are clearly different and the no. of screws below the balance wheel are different too. I really can't think of any reason for the makers to replace the stock balance wheel.
In my opinion, I think it's really fine for the bridges to be replaced by copies to achieve the PAM shaped bridges. However, I would really like to learn that crucial moving parts like the balance wheel, balance spring, wheels and gears to be stock from the swiss 6497. I'm not so sure though..
I may be wrong in my comparison, but these are what an amatuer like me have observed. Please correct me if my observations and comparisons are wrong.

Like I was saying the copy etas are coppies of the 6497-2 which has that balance wheel. Genuine Pams use 6497-2 as the base movements. If you get a movement that the balance wheel looks like the genuine Pams, it is an ETA copy. Eta 6497-2 have a higher beat rate and i am guessing that that balance wheel has something to do with it. Not really sure. Also Genuine 6497-2 as far as iknow are hard to get a hold of, also are rather expensive.

interesting...i was just -again reading the article of Ziggy....where one version of the 6497 movement had massive problems, because the balance spring was scraping on the movement and made it act totally crazy.
Please i am german, my english.....i would say is ok, but i am still having a hard time explaining specific things with its correct terms. no prob...in german i could do it perfectly....sigh
I suggest....from now on.....every UNITAS version rep watch needs to get this movement built in.....and nothing else !! no more problems....no more confusions......i promise !!

togokm....can you please erase the pic of this asian girl....she keeps looking at me...and she is harassing me sexually.....so, before i sue you....make her look somewhere else !!
Hi horologie_unitas, she's no asian girl.. She's Monica Bellucci, an Italian. The HOTTEST woman probably..
You should check out some of her movies, and you probably need to sue these movie makers instead of me... hahhahaha..

Excuse me for a minute while I go grab a kleenex to clean myself.

Going back to the subject, it means that if I get a balance wheel that looks like the gen Pams it's an ETA copy. So does that still qualify for what is described as "Swiss 6497"? Cos that's what I paid for..
And by the way, where do you get the pictures of that movement above? You know of any seller? Those 6497 I find on ebay are rather raw & unfinished.
you better be able to handle an italian women...trust me, 500 % the temper you can handle....
the movement was sold on e-bay some time ago....600 USD....it must be upgraded in very small quantities....
if we have a choice.....are gonna take the italian bombshell.....
or the unique, wonderful, hand built . swan neck regulated, 6497 with compensated hour wheel ?
tough....tough....very tough decision !!
smile......

I know I am kind of digging this thread out, but I have read and read now and can't seem to find an answer.
Some say the balance wheel spokes. But no definite answer on this.
Some say ETA stampings. But some of the Chinese copies have the stampings as well.
Some say the font. But how is one to tell without a side by side comparison??
Some say dagger vs needle. But what about the ones that are copies of the needle?
There are a lot more questions that have been asked and some have been proven to be the same on each model. So is there any sure fire way to tell?
The best one I have read so far, is what enzo said about the gold color piece that is opposite end of the needle itself. If it has a dimple in it or not. Anyone know anything to conflict with this method of telling the two apart?

In addition to the above, here is another question.
Do all swiss ETA 6497 movements have the stamp on them. Meaning did they ever make a 6497 without a stamp?

I'm not sure if it was on TRC or RWG that I read an article discussing this same subject.
From what I understood, you have to look under the balance wheel for 2 screws. The chinese version only has 1 and holds a part which function and name I can't explain.
Where as the swiss version has 2 screws holdign this same part.
Other than that, both might have the stamp and other similarities (as the chinese is trying to replicate the swiss).
If I come across the topic again, I'll let you know.
Cheers!
