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 with visual indicator system, and includes a black rubber strap with pin buckle and diver's extension.

Presented in very good condition, this Tudor Pelagos shows only minor signs of wear on the clasp and caseback. Accompanied by its full set (diver part of rubber strap missing).
