This is the Tudor Pelagos FXD “Ultra”, reference M2543C1A7NU-0001 — the most capable professional dive watch Tudor has ever built. Designed for saturation diving and real-world deep-sea performance, this 43mm diver features a full titanium case, helium escape valve, and an impressive 500-meter depth rating.

Despite its hardcore specs, the watch wears surprisingly well thanks to the lightweight titanium construction. The matte black dial ensures excellent visibility underwater, while the unidirectional dive bezel and luminous snowflake hands reinforce its purpose-built design. The titanium bracelet with fliplock extension allows for quick adjustment over wetsuits or drysuits.

Inside is the COSC-certified MT5612 calibre, offering 70 hours of power reserve, shock resistance, and anti-magnetic protection. This watch is delivered unworn and complete with a full set, including the original Tudor box, international warranty card, instruction manual, hang tag, and booklets, all dated 2025.

Whether you're a professional diver or a collector seeking Tudor’s most extreme tool watch, this FXD Ultra is the brand’s boldest expression of performance diving.
