Rolex Deepsea vs. Deepsea Challenge: What's the difference?

The Rolex Deepsea is an extremely durable and highly professional dive watch designed for serious underwater use, while the Rolex Deepsea Challenge is a far more extreme timepiece that represents the absolute peak of pressure-resistant technology. While the Deepsea is built for the limits of human diving at a more wearable 44mm, the futuristic 50mm Deepsea Challenge is engineered from titanium to survive the deepest point on Earth - at an astonishing 11,000 meters - making it a statement of technical dominance more than a practical daily-wear watch.

Here's everything you need to know to decide between Rolex's titans of the deep.
