The history of the tudor pelagos titanium automatic men’s watch replica is closely tied to its intensive use by professionals in underwater work, particularly by major navies throughout the world. The TUDOR collection was developed according to two main cornerstones, heritage and technology. The brand’s submersible products are genuine tools, which have evolved over the years to take into account the comments of these intensive users. When the Pelagos model was developed, it was with this heritage in mind and based on numerous tests carried out in real conditions all over the world – particularly on Lake Geneva, close to the TUDOR headquarters – that its characteristics specific to extreme diving were established.

Another essential characteristic of a good diving instrument is its readability. Several solutions have been adopted on the tudor pelagos blue dial replica watch model in order to optimise this. Its dial presents generously-sized square hour markers, complete with a large quantity of luminous material, a guarantee of greater effectiveness that provides excellent contrast. The luminescence is blue, the last colour on the spectrum to be discernible at great depths. Its hands, particularly the hour hand with its characteristic square tip, allows the wearer to distinguish it from the minute hand at first glance. Incidentally, this configuration, often known as “snowflake” in collectors’ circles, is emblematic of TUDOR divers’ watches produced from 1969 onwards. This is another way in which Pelagos fits perfectly into the brand heritage. With the same goal for optimum readability, the ceramic disc of its titanium unidirectional rotating bezel features luminous markers that allow for all information to be read even in conditions of extremely low visibility.

Its power reserve of approximately 70 hours tudor replica watches means that its wearer can, for example, take off the watch on Friday evening and put it on again on Monday morning without having to wind it. In addition to the hour, minute and central second functions, it provides an instant date display visible through an aperture positioned at 3 o’clock. Beating to a frequency of 28,800 beats/hour or 4 Hz, the calibre TUDOR MT5612 is regulated by a variable inertia oscillator with silicon balance spring spring, held in place by a traversing bridge fixed at both sides to improve resistance to shocks and vibrations. Its self-winding system is bidirectional. And, a first for a TUDOR product, it is certified by the Swiss Official Chronometer Testing Institute (COSC).

The first of these is substantial waterproofness, guaranteed to a depth of 500 metres and equipped with a helium escape valve, an essential device for preserving the watch during so-called “saturation” dives. This technique consists of saturating divers’ organisms with a gaseous blend of helium and oxygen, allowing them to alternate periods of undersea activity with rest periods in the chamber, and therefore avoid very long decompression phases for the entire duration of their mission. As the helium atom is the smallest gas particle in existence, after a certain amount of time it is able to penetrate the interior of the watch despite its waterproofness. The tudor pelagos replica escape valve therefore allows the gas to escape freely from the watch without damaging it during the long decompression stage in the chamber at the end of the mission. The helium escape valve accounts for this overpressure, and therefore any watch damage is avoided.
