Introducing the Supermarine 300m Date Bi-Colour, featuring a sleek profile case shape crafted in 904L stainless steel and 18ct rose gold.

The 18ct rose gold-capped, knurled-edged bezel showcases trapezoid indexes on the uni-directional brown aluminum insert, seamlessly transitioning onto the dial to form a naval-inspired crosshair that draws the eye to the striking brown gradient dial. Enhancing this design is the superior durability of the 904L steel case, an evolution from the previous 316L steel, paired with the clarity of applied indexes and Super-LumiNova® for exceptional visibility in low light. Completing the look is the elegant 18ct rose gold-capped screw-in crown.

Turning the case over reveals a case back engraved with a map of the world’s oceans, highlighting the purpose-driven design of this practical yet elegant sports watch.

Continuing our commitment to innovation, the Supermarine 300m Date Bi-Colour is fitted with our newly designed 904L steel bracelet. Featuring alternating polished and satin-finished infinity-shaped links, it offers exceptional fluidity and versatility.

For those seeking alternative styles, the Supermarine 300m Date Bi-Colour can also be paired with a quick-release brown leather strap with cream side stitch, adding its own distinctive character.
