Is the Omega Red Gold Watch pure gold?

I don't think so. It should be Jinbao.

Omega (symbol: ω) is a Swiss watch brand, which belongs to Swatch Group and was founded by Louis Brandt in 1848. Omega's four classic watch series are Constellation, Hippocampus, Motorized Altman and Disc Flying. The last process of his watch has been kept by hand.
