Looking at the three subdials, you’ll notice a slight difference in hue amongst them. Like the winners’ podium at the games themselves, you have a tiered display of gold, silver, and bronze. The colors are close enough that from a distance you might not notice, but up close it provides enough contrast to be obvious and interesting. Importantly, these are actually 18k yellow gold, 925 silver, and bronze, not just color imitations. A special Rio 2016 engraving on the caseback finishes things off.
