This replica deepsea 126660 in blue brings the D-Blue gradient dial to the 44mm Deepsea case, a color combination that debuted in 2014 as a tribute to James Cameron’s solo dive to the Mariana Trench. The gradient transitions from bright blue at twelve o’clock to jet black at six, creating a visual representation of descending ocean depth. Reference 126660 carries the same 3,900-meter water resistance as its predecessor while updating the movement generation. The green “DEEPSEA” text at the bottom of the dial adds a contrasting accent that has become the visual signature of this particular model.

The D-Blue dial is not a simple two-tone print. On the genuine reference the gradient is achieved through a process of depositing layers of color on the dial surface, which gives the transition a smooth, almost liquid quality under different lighting conditions.

Design & Finishing

The blue-to-black gradient does something unusual for a tool watch — it adds visual drama without sacrificing legibility. The luminous hour markers and hands remain highly visible against both the blue and black sections of the dial. The green “DEEPSEA” text at six o’clock is the only non-monochromatic element, and it draws the eye downward in a way that reinforces the depth theme. Compared to the 43mm Sea-Dweller 126600, this model commands more wrist space but also delivers far more visual impact.

On the Wrist

At 44mm and nearly 18mm thick, the D-Blue Deepsea is a statement piece. It suits larger wrists and works best on short sleeves or rolled cuffs where the full case profile is visible. The gradient shifts noticeably between indoor and outdoor light, appearing more blue in daylight and more black under artificial lighting. For anyone drawn to the Cameron dive story and the engineering behind the deepest-rated Rolex, this replica deepsea 126660 in D-Blue is the most visually distinctive way to wear that legacy.
