Vintage Rolex as an example a 5513. Serial Numbers are stamped on the case not on the movement. So if the movement is totally wasted -say a 1520 movement as an example- and you find a new one or a good used one- and install/replace the wasted one using the same case, no issues since no SN on the movement. It is a totally legit 5513- no need for an extract, no need to know how this 5513 really was sold as a 5513. And yet some Rolex timepieces use the same movement. Not true with Omega SM 300 with caliber 562 or 565 correct? Different Omega models use same movements hence the need for an extract using the movement's SN to prove authenticity as to whether it is a legit SM 300 or just a right movement in a wrong case.
If I am correct, which one is better?
Thanks.

 

Rolex movements have a caliber number, top picture, as well as a serial number, bottom picture. This is from a ‘61 GMT I owned. Rolex does not make archives information available

 

???? That is the old Apple versus Oranges thing.....Better? They are different and stand alone watches in their own right. There are a lot more fake Rolex cases from Vietnam on the market , than changed Omega Movements. And these fake Rolex cases are very good now ! So, what was your question again ? Kind regards. Achim

 

Not every Rolex Movement has a serial number.....

 

Thanks for sharing the knowledge. Obviously I am not as knowledgable as you are Achim. That is why I added "If I am right" in my post. I know that there is caliber no on the movement but not an SN that can identify if the movement is for a Sub or say (again as an example ) a Precision that uses a cal 1520.

 

Imagine (however improbable) that one day Rolex offer archive extracts. What will it do to the value of some of the high price vintage pieces to find that the movement number does correspond to the one originally fitted. A bit of food for thought while I eat my lunch.

 

I don't understand what you are asking here. How could one of these be better? They are just different.

 

Okay then. Thanks.

 

My point exactly.

 

what is this post all about? i have rolexes and omegas. i like them both regardless of whatever biases any one have.

 

By the way, apple and orange are both fruits.

 

Love them both too-no bias. Thanks.

 

Just as not every Omega movement has a serial number...

 

My apology to all as I never intended to upset anyone. Sometimes we have to ask pointless question without intending to. My motive is to learn and to me Omega and Rolex timepieces are both great as well.

 

Actually, a very well-guarded secret is that they are in fact the same company, but shrewdly created an artificial opposition perception to cover all sides of the middle luxury watch market.

 

With how personnel in the industry move from one company y to another, there's some truth to this. If you look at the Cal. 8500 and a hire they made previous to the caliber, you would see the influence...

 

Which one is best?
The one YOU like most!
There is no perfect brand or perfect watch for everyone!

 

endless debate and pointless. let's just co-exist as vintage nuts.

 

Actually I wasn't talking about which one is the best/better. I was talking about their method/system about SN placements to help identify what movement came with model. Thanks.
