Which is more classic, Rolex Submariner or Rolex Sea-Dweller? Rolex watch fans argue indefatigably about the topic and there isn’t still the only answer. Today, I’ll introduce them from the history, development, features and differences.   

Historical Background
As for Rolex Sea-Dweller, I have to refer to Comex, a French company in undersea engineering established in the 1960s. It was at that time that Andre Heiniger, CEO in Rolex, was interested in deep-sea dive, and Rolex started a cooperation with COMEX. Rolex volunteered to offer Rolex diving watches, and COMEX would send suggestion feedback of performance data in the real undersea environment back to Rolex. To distinguish those watches for COMEX and models for sale, those watches for COMEX were printed with comex, so every of Rolex comex diving watches had been to the undersea. The watch for COMEX is Rolex Submariner or Rolex Sea-Dweller. When are there differences between them?

Rolex Submariner built its senior status in the diving watch field after it was established in 1953. It’s in 1967 Rolex Submariner diving watches printed with comex were regarded as experimental products for COMEX company. Rolex had planned to develop another model since then. Rolex improved those diving watches and called the model the Sea-Dweller according to feedback data from COMEX, so Rolex Sea-Dweller was inclined to be a diving tool with strong resistance to water.To this day, maximal waterproof depth of the Submariner is 300 meters, while the Sea-Dweller Ref.116600/Ref.116600-0003/Ref.126600 and the watch is water resistant to 1,220 meters, and the Sea-Dweller Ref.116660-98210/Ref.126660/Ref.126660 D-Blue Dial extends to 3,900 meters.
