Tudor Pelagos LHD 25610TNL


The TUDOR Pelagos technical divers? watch is now available in a “left -handed” version. Equipped with TUDOR manufacture movement and featuring a black dial and black bezel, each model is numbered.


Titanium’s natural qualities explain its choice for the case and bracelet of the TUDOR Pelagos. Light and only 60% of the weight of stainless steel for the same volume, it is also very resistant to the corro- sion caused by seawater. The matt appearance of its entirely satin nish, its technological overtones and its colour all serve as an excellent means of commu- nicating the technical vocation of this watch in terms of its design. Like its case and bracelet, the TUDOR MT5612 movement with which the TUDOR Pelagos is equipped also has matt nishings – sand-blasted, machine-tooled or with a sunray nish suggestive of robustness, precision, reliability and a high level of technological expertise. 


The waterproofness of the Pelagos model is guaranteed up to 500 metres (1,640 ft) and has been systematically tested to 125% of its capacity, that is, to 625 metres (2,050 ). This extreme water- proofness is coupled with an automatic helium escape valve, an indispensable device designed to safeguard the watch during “saturation” dives. This diving technique involves saturating the bodies of divers with a mixture of helium and oxygen gases, enabling them to alternate periods of underwater activity with periods of rest in a hyperbaric chamber so as to avoid very long phases of decompression during the dive. The helium atom is the smallest gas particle in existence. It manages over time to penetrate the inside of a watch in spite of its waterproofness. In this case, the automatic helium escape valve enables the helium gas to escape from the watch freely during the decompression phase – much shorter than the immersion – without damaging it during the dive. Without this type of system, the excessive pressure created inside the watch by the presence of a large number of helium atoms would cause it to explode during decompression. 


The dial of this new Pelagos watch has been reworked with beige luminescent markings and the name “PELAGOS” in red at 6 o’clock. The calendar disc, in beige too, also comes in a new design, with its numbers displayed in alternate colours: the even days are displayed in red and the odd in black. 


This aesthetic detail, nicknamed “roulette” by collectors, was especially characteristic of TUDOR divers’ watches with its dial and “snowflakes” hands that rst appeared in reference 7021 in 1969. In the same vein, the unidirectional rotatable bezel in ceramic has beige luminescent markings to match those of the dial. 

In keeping with the nest traditions of giving tool- watches dedicated reference numbers, Pelagos LHD is produced as a numbered series.

Each model has a unique production number engraved in large Arabic numerals on the case back. This is a rst for TUDOR.
