Longines lately unveiled its Twenty-Four Hours watch in advance of the Basel 2011. As a timepiece to be launched in the coming Baselworld 2011, the Longines Twenty-Four Hours has its origin back in the 1950s. At that time, as the watch supplier for the Swiss national airline – Swissair, Longines designed a timepiece with a distinctive 24-hour dial, which is the original prototype of this Longines Twenty-Four Hours watch. As expected, this 24-hour dial feature greatly meets the needs of the aviators who have to depend on the watch to determine the position of the plane and figure out a flight plan. Below let’s take a look at this newest update of Longines. Measured in 47.5mm in diameter, the case shows a round shape with stainless steel as its material. At three o’clock of the dial is located with a winding brown, like most of the watches it produced. Covered by a sapphire with non-reflecting coating glass, the matte black dial is clearly viewed. Characterizing the dial is the 24 white Arabic numerals with Super-LumiNova, which are distinctively organized inside. Embracing the 24 numerals is the larger railway track minute circle with small numbers before it. The three centralized hands are specially designed with the hours hand in skeleton pear shape, the minutes hand in skeleton leaf shape and the seconds hand showing a long thin strip. The date aperture has its location at 3 o’clock. Powering the Twenty-Four Hour is the Calibre L704.2(ETA A07 171), a self winding mechanical movement. It contains 16½ lines and 24 jewels. The power reserve capacity is 48 hours. Finishing its impressive look is the alligator leather strap, in black, brown or beige.
