The story behind this Tudor Pelagos Ultra
Unveiled in 2025, the Tudor Pelagos Ultra takes the lead in a line first launched in 2012, when the brand relaunched its range with a titanium diving watch, fitted with a helium escape valve and water-resistant to 500 m. Following the switch to an in-house calibre in 2015, and the subsequent launch of the Pelagos LHD and the Pelagos 39, Tudor returned to the standard model with a specific question in mind. What does a diving watch need to function in the twilight zone, at depths of between 200 and 1,000 metres? The answer lies in a case enlarged to 43 mm and water-resistant to 1,000 metres, a two-tone luminescent finish in blue and green, and a strap entirely redesigned for deep-sea diving. The Snowflake hands, a signature feature of Tudor diving watches since 1969, remain at the centre of the dial. This model, reference M2543C1A7NU-0001, joins the collection without replacing the Pelagos 500 m.
Case, movement and strap of this Pelagos Ultra
The 43 mm case, 14.5 mm thick, is fully satin-finished. The case middle, bezel and crown are made of Grade 2 titanium, the screw-down caseback is made of Grade 5 titanium, and the helium escape valve is situated on the side at 9 o’clock. The screw-down crown, embossed with the Tudor shield, is flanked by two crown guards. The unidirectional bezel features a matt black ceramic insert and a fully luminescent 60-minute scale. Beneath the domed sapphire crystal, the matt black dial with a sandblasted flange features monobloc applied hour-markers in luminescent ceramic composite, with the date at 3 o’clock. The in-house MT5612-U calibre, with a bidirectional automatic winding rotor, beats at 28,800 vibrations per hour on 26 jewels and offers a 65-hour power reserve. Certified by the COSC and subsequently by METAS to the Master Chronometer standard, it is resistant to magnetic fields of 15,000 gauss. The satin-finished titanium three-link bracelet fastens with a T-fit folding clasp featuring a locking flap, with quick-adjust length adjustment, a diving extension and a luminous position indicator.
Why this Tudor watch
The Pelagos Ultra is aimed at those seeking a fully-fledged diving instrument rather than a vintage-style interpretation, the approach taken by the Black Bay. With a water resistance of 1,000 metres, this Tudor Pelagos watch doubles the water resistance of the 500-metre version and adds Master Chronometer certification. Titanium, which is lighter than steel, makes its 43 mm case comfortable to wear on the wrist or over a wetsuit. Purchased in June 2026 and supplied with its two straps, it remains covered by the Tudor 5-year warranty – which is transferable and does not require registration – until June 2031.

The watch is in mint condition, with no marks visible to the naked eye on the case, bezel, crystal or strap.
