How many grams of gold does Omega contain?

Omega constellation second-hand rose gold or gold, which is more expensive?

Omega constellation second-hand rose gold can't compare with gold because of the unequal items. Watches only have 18k gold, which is rose gold, and honey and dark red, which are all gold. Gold is 24k, which is generally considered as gold. There is no 24k gold watch. If the goods are not equal, there is no way to compare prices.
