Is Hublot’s New Red Gold Watch Actually Red Gold?

Hublot's Big Bang Caviar Red Gold Diamonds ladies watch

For Hublot’s Baselworld preview, the Swiss luxury watch brand released images of its “5N red gold” Big Bang Caviar ladies watch, featuring a bezel set with 36 diamonds. As you can see in the picture it is quite a beauty. However, I have a bit of a dilemma that I will get to the bottom of eventually.

From my understanding of the different colors of gold, 5N refers to rose-colored gold, while 6N refers to red gold. Pink gold is usually 3N and 4N gold. The colors are based on the types of metals that are mixed with pure gold. Usually 18k gold, which I am assuming this watch contains although the materials don’t clearly state this, is mixed with cooper to make it red. Red gold can be made with 75 percent yellow gold and 25 percent cooper. However, I believe this is usually labeled as 5N gold, which refers to rose gold.

Anyone who has an answer is welcome to respond. I will ask Hublot when I get the chance. I’m sure there’s a simple explanation.

Now for the rest of story behind this watch. It’s based on the design of Hublot’s famous One Million $ Black Caviar, and directly inspired by the black ceramic Big Bang Black Caviar, which has been one of the brand's bestsellers since 2011. The 41mm watch has a sleek, graphic look with sharp angles and reliefs designed, cut, beveled and polished to look like the black baguette diamonds on the Caviar watch.

It's fitted with the HUB1112 self-winding mechanical movement. The 5N gold dial has a date window at 3 o'clock. It has a power reserve of 42 hours. The strap is made of either shiny silver or 5N gold colored calfskin sewn onto black rubber.

The timepiece also is available in a steel version, with 36 diamonds on the bezel and the same size, movement, look and workmanship as the “red” model.
