The replica royal oak offshore 26400SO deep blue takes the 44mm steel and ceramic chronograph into its darkest blue variation. The main dial runs a deep navy Mega Tapisserie while the sub-dials push even darker, creating a tonal contrast that gives depth to the face without introducing a second color. Crown guards and the black ceramic bezel frame the whole composition against a rubber strap — understated by Offshore standards.
Deep Blue Sub-Dials and Tonal Contrast
What separates this reference from the other blue 26400SO models is the sub-dial treatment. Where the standard blue and bright blue versions use white or contrasting sub-registers, this piece keeps everything within the blue spectrum. The 30-minute counter at 12 and the 12-hour counter at 6 sit in a deeper shade than the main dial, readable but not disruptive. The running seconds at 9 follows the same approach.
Under indoor lighting the dial appears nearly black. Move outdoors and the Mega Tapisserie pattern reveals the deep navy base as light catches each facet at different angles. It is the most tonally cohesive dial in the 26400SO range — a single color explored at different depths rather than mixed with contrasting elements.
Compare it directly against the standard blue .01 variant and the mood shift is clear. Same case, same ceramic bezel, different character entirely.
44mm Steel, Ceramic Bezel, Rubber Strap
This replica royal oak offshore 26400SO deep blue shares its architecture with every 26400SO chronograph: 44mm stainless steel case, black ceramic octagonal bezel with eight hexagonal screws, and integrated crown guards housing the chronograph pushers and screw-down crown. The SO material combination gives you steel durability where it matters structurally and ceramic hardness where surface wear accumulates fastest.
The Cal. 3126/3840 operates at 21,600 vibrations per hour across 59 jewels. Power reserve holds at 50 hours. The chronograph resets to zero without hand-stack misalignment, and the pushers provide consistent resistance through the crown guards. These are functional details that matter when you use the chronograph regularly rather than treating it as decoration.
Rubber strap with a steel AP folding clasp, 100 meters of water resistance. The strap matches the deep blue tone of the dial. For any questions about this reference, reach us through our contact page.
