The Rolex 16233 is a special watch because it is a two-tone model. That means it is made up of durable stainless steel as well as elegant 18k yellow gold. Stainless steel is a sturdy alloy that stands up quite well to scratches. Gold, which is a naturally soft alloy, can be scratched more easily. However, the 18k gold alloy used by Rolex is the highest quality on the planet. Additionally, since the 18k gold is only used on the links of the bracelet, as well as on the fluted bezel, you have less opportunity to scratch up these softer surfaces.
