If you do not mind my asking: it has a sticker on the back, does it "conceal" the engraving "Omega Centenary" or it is supposed to stay there?
When the watch was originally sold, that sticker would have been discarded, either by the store or the owner. Incredibly rare to see that today and I know that @MSNWatch would never remove it.

I wonder if there is a non-invasive technique that can tell if the engraving is there without touching the sticker?

Dear watch lovers,

I am new here to the forum and also relatively new to Omega Vintage watches. Among aome othe rbrands and contemporary modells, from Omega I currently own a Speedmaster MarkII Ref 145.014 and a Constellation Ref. 1502.40.00 and am looking for ideas to add something golden to my collection.

During some research towards this direction, I stumbled across the Constellation's predecessor line, the Centenary line with, among others, Ref. 2500. Production started in 1948, solid-gold, chronometer (first automatic chrometer movement for the company's 100th anniversary). The watch was produced exclusively in solid gold and in limited numbers before it was replaced by the Constellation series a few years later.

Unfortunately, there is very little information about this watch on the web, apart from an article on Fratello's, I didn't find much background info about this reference.

In the 2000s, as part of the museum line No. 5 Ref. 5704.60.02 was introduced with a slightly larger format, rose-gold and equipped with a contemporary Co-Axial movement.

I really like both of them and could imagine adding them to my modest collection if the opportunity arises. Of course, the search for a good example of the 2500 in particular takes time, patience and a little luck.

Here are my questions for you:

Does anyone here have one or even both of these references?

why is there hardly any content about these watches on the web?

In your opinion, would a full gold Constellation Vintage be a better alternative? If so, why and which ones?

For me as a vintage beginner: what do I have to pay attention to? Due to the limited content found, it is difficult to make real comparisons to an original, untampered watch when it comes to potential offers.

Which do you like better: Original Vintage or Re-Edition and why?

Thank you
Biaesch
I have the 2500 model -- these are beautiful. I tend to wear my pie pan dial connies much more often, but the history behind the 2499/2500 is what makes these watches special. If you are going to get one, look for the ones that still have the "Omega Centenary" marking on the back. They are harder to find, but in my opinion worth the wait.
