A model reminiscent of Tudor's experience in the 1950s, when it took part with its watches in a British scientific expedition to Greenland for a series of experiments in the most hostile conditions imaginable on Earth, the North Flag is equipped with the brand's first manufacture movement: the MT5621 automatic calibre with a power reserve of around 70 hours. A novel detail for Tudor, the movement is visible from the back side. The power reserve is displayed on the dial at 9 o'clock. The satin-finished steel case features a bezel composed of two perfectly integrated and complementary elements, combining matt ceramic on the side and brushed steel on the top. The dial is black with yellow and white details.
