I would guess a dial swap based on case and reference number

 

Wow @mac_omega what a beautiful watch.

 

Man, what an absolute stunner

 

On ebay there's a ref. 2497-5 / cal. 265 with similar dial and a 12.0 mio. serial #:

This one looks immaculate

 

That has got to be one of the most horrible crown replacements I have seen. At least it can be easily fixed.

 

Well, @mac_omega's watch is immaculate, the eBay one is ... ahem ... let's just be kind and say the dial is tired.

 

I am sorry for interfering but I would like to take the opportunity and ask @X350 XJR , if the indication "Calatrava" addresses only to Pateks. I've seen hundreds of Longines described as "Longines Calatrava" and I would like to clarify if this description is true. However I have to admit that it's the first time I see the description "Calatrava" to an Omega...

 

Calatrava is a line produced by Patek Philippe. Nobody else.

That's all there is to it.

Imagine a Longines Royal Oak , or an Omega Sea Wolf . Same thing in essence.

People flogging watches try to ride on the reputation of PP, and elevate their sometimes shitty offerings to PP levels.

On the other hand, "calatrava style" could be used, but it's still trying to polish a coprolite.

I'm sure @X350 XJR would agree.

 

you will find an extensive (and amusing) discussion on the subject below.

yes I have seen also Tissot seamasters instead of seastars.. however the Longines Calatrava are so often found that I developed a sense that they exist!!

 

"If you tell a lie big enough and keep repeating it, people will eventually come to believe it."

 

I see "Calatrava" and stop reading on the spot.

 

I don't even know what a “Calatrava style” would be anymore, it's being used for anything with three hands.

 

Another proof that watch styles really cut across all brands, in many instances. Serial number dates it to 1957-1958.

 

The dial is cool, but look at those lugs!

 

Just sharing is what I think the closest one for the model and reference picture from omega vault.

from the Calatrava Style era

 

I find anything vintage with a subdial in the Italian market is a calatrava.

We won’t stop it as I noticed a Daniel Wellington called a calatrava style watch in a magazine on a plane a year or two ago.
