Tudor was founded in Geneva in 1926 as a sister brand to Rolex, built to offer Swiss-made professional tool watches at a more accessible price point. The Pelagos Ultra, introduced in 2025, takes the Pelagos formula to its logical extreme — a watch built around a single brief: to go deeper than anything Tudor has produced before. With 1,000 metres of water resistance and a COSC and METAS-certified manufacture movement, the Pelagos Ultra makes a serious case for being the most capable production diver's watch at its price point.

Reference M2543C1A7NU-0001 is a 43 mm fully titanium automatic diver's watch, 14.5 mm in thickness, with a satin-finished case and a helium escape valve at ten o'clock. The matte black dial carries a sandblasted flange, Tudor's signature snowflake hands and square luminescent hour markers for maximum underwater readability. At its heart beats the Tudor Manufacture Calibre MT5612-U, both COSC and METAS-certified, with a 65-hour power reserve. The domed sapphire crystal sits above a solid titanium caseback. The unidirectional rotating bezel is titanium-framed with a matte ceramic insert and luminescent diving scale. Water resistance is rated to 1,000 metres. The watch is fitted on a titanium three-link bracelet with Tudor's T-fit folding clasp, safety catch and diver's extension, and includes a black rubber strap with pin buckle and diver's extension.

This Tudor Pelagos Ultra is in near mint condition and comes as a full set with factory warranty until 2029.
