D-Blue dial and large luminescent hour markers. This timepiece showcases a perfect two-toned gradient dial, starting from a brilliant blue hue at the top to the engulfing black depths below. Its two-color gradient dial commemorates the accomplishment of man’s journey into the ocean depths, exploring the deepest place on earth — the iconic Mariana Trench.

Replica Rolex Sea-Dweller Deepsea, like the famous Submariner, only more so: it’s beefed up, specced out and all-around badass. While the Submariner is a capable dive watch, it’s so handsome and versatile that the vast majority of units sold will probably never get very wet. The Sea-Dweller, on the other hand, is resolutely made for extreme underwater use — it’s the OG hardcore dive watch. When the Sea-Dweller debuted in 1967 it existed within the Submariner line. It was rated to go significantly deeper (610m) than the existing Submariner (200m water-resistant at the time) and it incorporated a helium escape valve — a feature created specifically for professional divers living underwater (or in pressurized environments) for extended periods.
