Certainly not limited to Omega but I really, really hate it when sellers describe a yellow gold watch as "Pink" or "Rose":

It's a real turnoff, as well as instantly making me doubt the intentions of that particular seller. Yellow is yellow and pink is pink and ne'er the twain shall meet. I'm sure not all do it for the extra money but then ignorance is not exactly the best defense either.

That's eBay for you. Caveat emptor is not strong enough - a buyer should expect shenanigans so they're pleasantly surprised when something arrives as described or better. Devia expectus.

 

Sometimes pink gold can be tricky....different lustures and amounts of copper are added, some gold watches look pink in certain lights.

 

I don't agree and to me the buckle & case look the same color--yeller:



For me, this is pink/rose:



YMMV & best,

The first is definately gold, second one pink.

 

Conquests, and Longines of the 50's & 60's in general, might not be a great example because they had an orangy-rose color gold too - as did JLC. Here's my 1960 Conquest:



It's not yellow, and it's not pink.

 

What ever it is, it is beautiful!

 

Thanks. For a few years this was the crown jewel of my vintage collection. It has to share the spotlight with the Centenary 2500, Constellation 2799, and JLC E855 Memovox now. I still haven't seen a Conquest in better condition.

 

That is a gorgeous watch and pretty much a perfect example of a Longines I would love to have in my collection...and it's also clearly yellow gold.
Look, there is no doubt that old yellow gold takes on warmer tones as time goes by and that the mixture varies by era and manufacturer due to the percentage of alloys used. Heck, there is even green gold as found on old Hamiltons and Illinois.
But pink shows differently than yellow, even though there are different hues of PG, too (technically Pink, Rose and Red gold but that's not an easy thing to discern with the naked eye). That's because all yellow gold has about 2% give or take of copper alloy while pink mixtures have 20-25% copper.
Even allowing for naturally occurring variations, when you put a yellow gold watch next to a pink gold watch, the difference is clear, IMO.









Please excuse the Rolex content.

Some pink gold versions are very clear to define but others are quite close to yellow gold.

 

Lovely watches and that can be true, especially if a pink watch has sat for many years without wear or polish, as they can discolor. And of course the color balance of a photo is also important in our perception of it.

But the salient point is that it is the seller's duty to describe his items accurately since he is the one actually in possession of them. And if he can't tell pink from yellow gold then maybe he better find someone who can tell him what it is (any jeweler will be able to in about 5 seconds) or leave off describing it as the more valuable commodity so he does not make us think him a fool...or something worse.
It's not fair to buy a "pink gold" watch and take delivery of one that is actually yellow.
Best regards,

Only quick tip off on that top one is the date disc.
