Renewed Panerai Mare Nostrum 52 Mm Watch

The most mysterious and precious Mare Nostrum watch from Panerai is reissued. The re-introduced Mare Nostrum watch faithfully reproduces the main features of this classic chronograph stopwatch: case design, chronograph function, dial and production process. The new watch not only exudes strong historical charm, but also brings us powerful visual shock.
    Mare Nostrum is a professional chronograph supplied by Panerai to the Italian Navy in 1943. At the time, this chronograph was standard equipment for naval officers. History is constantly evolving. However, development of this model has stalled. At the beginning, the watch factory only produced a small number of trial works, and we were almost sure that there were only three in total. These trials gradually disappeared, and a flood that hit Florence in 1966 also claimed all relevant records.
    Very lucky. Panerai found one of the prototypes and passed on the Mare Nostrum watch. This watch is still in the Panerai Museum in Florence. Panerai strictly reproduces 99 Mare Nostrum watches in accordance with the trial works. The reprinted version is the same as the trial works even with the smallest details. For watch collectors, this is undoubtedly the most valuable and extraordinary work.
    The new Mare Nostrum, like the trial work of the year, has a striking frosted case made of three parts with a diameter of 52 mm. The watch is equipped with sturdy lugs, and its wide and flat bezel makes the barrel-shaped case look round. Like the trial work of the year, there is a very conspicuous and delicate circle mark on the table frame. This may be the trace left by the unfinished process at that time, or it may be a reference mark for engraving the scale later.
    The screw-in case back has four grooves to unscrew it. It is also made of frosted stainless steel, but unlike the previous trial, it is also equipped with a sapphire crystal glass window to view the movement inside. . The cylindrical winding and the crown of the adjusted crown are engraved with the words Mare Nostrum. The crown has a screw-in design and the buttons have a cylindrical structure.
    The water resistance of the watch was 3 bar (about 30 meters), which was determined by the use of Mare Nostrum at the time. There are two reasons for this. First, the watch was designed to be used on board rather than underwater. Second, due to the technical conditions at the time, it was impossible to set any timing button on the completely waterproof watch.
    The dial has a black base and consists of a two-layer structure, while being protected by a 1.6 mm thick anti-reflective sapphire crystal glass. The upper ring of the outer ring is printed with small Arabic numerals, holding hour markers and round minute markers, all covered with luminous material. The middle layer is sunken about one millimeter, with the brand and model name printed on it, and two small dials attached. The small seconds on the left and the minute counter on the right are set to 45 minutes according to the norm at the time. The significant drop between the two layers of the dial creates a unique sense of depth. The chronograph hands are not covered with luminous materials like the hour and minute hands, but instead follow the blue chronograph design of the trial work of the year.
    Just like the trial work of the year, the new Mare Nostrum watch is equipped with an OPXXV manual winding movement. This movement is derived from the Minerva movement, with a diameter of 16¾ legal minutes. Its balance wheel, like the prototype Angelus movement, vibrates 18,000 times per hour. The column wheel movement is equipped with anti-vibration device, which can be seen through the window on the case back, and all levers are polished and rounded.
    The Mare Nostrum watch of model PAM00300 also uses the tone and material of the strap of the trial model of the year: military green fabric strap. However, the buckle is now in the trapezoidal shape of Panerai. And bigger than the original model.
