The stain or light 'discoloration' comes from oxidation, pure contact of gold with air. Some blends (as Rolex everyose) delays that process. Just as with silver, if you use your gold watch daily, rubbing against your shirt, clothes, water, etc. will not allow the oxidation to take place as fast, as you are 'micro-polishing' with daily use.

Rolex's answer is to add more platinum to the 'blend' to make it more stable, Hublot's approach was to increase dramatically the gold's hardness. Rolex calls it ever rose, while Hublot calls it magic gold. Two different objectives, one is to make luster last longer, the second to make it harder to resist scratches.
