Terra Cielo Mare, a family-run company that has been in business since 1999, presents the Zero-Sen. This name owes its origins to the period of World War II, when the Americans nicknamed the Mitsubishi A6M, one of the most important Japanese warplanes in history, the Zero-Sen, which also flew the skies over Pearl Harbor. A commemorative timepiece, therefore, steeped in history, designed with the help of the Ali Storiche association, which allowed Terra Cielo Mare to come into possession of an original piece of aluminium from a Mitsubishi A6M. In particular, it is the part of the nacelle where the flag of the Rising Sun was printed, from which the precious red plaque inserted on one side of the Zero-Sen's carrure was obtained. The Zxero-Sen is therefore an aviation watch, but with nautical characteristics, derived from the historical origin of the aircraft from which it takes its name, which was in fact embarked on aircraft carriers. The dial shows 12 hours on the outside and 24 on the inside. The back, on the other hand, which is tightened with screws on two levels in sapphire crystal and titanium, is equipped with a Slip and Skid inclinometer, with left and right indications in Japanese ideograms, which allows the pilot to orientate the plane's turn. The Zero-Sen, like its twin "The Green Sorci", is also powered by an automatic mechanical movement, calibre TCM-3900, specially created by Concepto of La Chaux-de-Fonds. These operations are in fact possible by turning the bezel of the watch. The crown has been replaced by a release lever, positioned on the left side of the case middle, which, when closed, allows winding, while when open, it enables the time to be adjusted by rotating the bezel. This operation is reminiscent of the winding and setting systems of aviation watches, designed to be used with gloves on. The case, like that of Il Sorci Verdi, is in sandblasted titanium with black DLC treatment. The Zero-Sen is available in a limited edition of 88 pieces. The numbering is indicated on the dial through a stamping process, which is more complex than manual engraving, but decidedly more faithful to the original design of the instrument.
