Tudor Pelagos Ultra M2543C1A7NU-0001 – History

The Tudor Pelagos Ultra marks a significant evolution in Tudor’s dive watch tradition, delivering a professional-grade timepiece engineered for modern exploration. Born out of Tudor’s decades-long legacy of tool watches and deep-sea performance, the Pelagos Ultra elevates practical design to new heights with a robust 43 mm titanium build and industry-leading technical features. It represents the brand’s commitment to creating serious dive watches that are equally at home in extreme underwater environments and everyday wear.

This reference showcases a contemporary take on Tudor’s Pelagos lineage — blending rugged capability with refined functionality. From its impressive water resistance to its improved legibility and ergonomic innovation, the Pelagos Ultra stands as a compelling choice for aficionados of advanced mechanical dive watches.

Design and Aesthetic

The Pelagos Ultra is crafted around a 43 mm titanium case that balances strength, lightness, and wearability. The use of both Grade 2 and Grade 5 titanium gives the watch a durable yet refined presence on the wrist, with satin-finished surfaces that accentuate its technical character.

The black matte dial is clear and purposeful, with oversized markers and hands designed for optimal legibility under all conditions. The minute hand and dive-scale pip feature contrasting luminescent colors to simplify elapsed-time tracking in low-light or underwater environments.

The watch includes a unidirectional rotating bezel with a matte ceramic insert and a helium escape valve — both essential tools for saturation diving — reinforcing the Pelagos Ultra’s professional intent. A date window at 3 o’clock adds practical everyday functionality without distracting from the dial’s clean symmetry.

Movement: Manufacture Calibre MT5612-U

At its core, the Pelagos Ultra houses Tudor’s manufacture automatic movement, delivering reliable performance and robustness:

Self-winding mechanical calibre with a bidirectional rotor system
COSC and METAS-level precision for consistent timekeeping
Approximately 65-hour power reserve, ideal for regular use
Date complication for everyday practicality

This movement pairs Tudor’s technical credibility with practical performance, making the Pelagos Ultra both a serious dive instrument and a versatile daily wearer.
