A quick note about Gold

There have been a few off the cuff remarks and incorrect conclusions about "Red Gold" vs. "Pink Gold" lately, on and off line, and I just wanted to give the actual breakdown of metals in each one.

Red Gold is 5.5% copper and 94.5% Gold

Pink Gold is 6% silver, 19% copper, 10% palladium, 5% nickel and 60% pure gold

Just to be clear on the matter. There can be slight changes in these formulations, but these %'s represent the bulk of the Red vs. Pink Gold alloys used in watch making.  I have had several conversations on and off line lately where many collectors and even some retailers were not aware of the difference in the two alloys. I am more of a White Gold fan myself (10% copper, 10% palladium, 5% nickel and 75% pure gold) but that is just personal taste.
Maybe one of the Hour Lounges has a good comparison photograph and then we can really put the issue to bed.
This information is also published off line in the V&C desk top calendar.

Best to you all,

Antiquorum gives a great breakdown of the formula for pink gold vs red gold: All gold starts out pure yellow, ie 24k.  Modern 4N standard for pink gold begins with 75% pure gold, ie 18k, with 16% copper and 9% silver. By comparison, today's 5N standard for red gold adds 20.5% copper to the 75% yellow gold base, and only 4.5% silver.  This is why pink gold was slightly more expensive to produce. They also note that vintage formulas for pink gold were quite variable - anywhere from 20 to 25% copper!  This certainly explains why some older watches described as pink gold appear quite red
Well, now I'm confused

To repurpose the old saying about watches: "A man with one formula for pink gold knows what's on his wrist, but a man with two formulae is never sure!" I may be reading incorrectly, but the proportions in these two sets of formulae look different to me -- and Tim, the gold in yours doesn't add up to "750."  Can you guys (or others) clarify or point out where I'm misunderstanding! Thanks, GaryG

Hi Gary, Sorry for the confusion, Dean's numbers are more clear in

the modern formulations. I was actually frustrated that several conversations recently had lead to an incorrect conclusion that Red and Pink gold are one in the same--they are not. The numbers I quoted are vague, and not meant to infer that a watch marked 75% gold is anything but that, just that these other metals can be used to alloy with pure gold to get it that beautiful Pink color. Sorry for the confusion on my part, not up to Hour Lounge standards, but that is why Dean sits vigilant up North, you just have to love that guy. Best to all on a rainy Friday, Tim

Now come on Dean, you have to have a gold helmet after all that

gold talk. But could you make it white gold for me! Thanks Buddy, Tim

At page 5 in the in the ´Useful Information´part By the way, I love that desk top calendar, too. It is a very good reason to use my pen´s more often Best Oliver
Yes indeed. There are just so few of us that still use INK!

Best to you my friend, Tim
So what makes up the 5% that isn't Platinum

in a 950PT case? G
other metals from the platinum family such as iridium nt
