These years, Longines Vintage watches are hot in the world. 2011 is definitely going to be a year of remakes! At the upcoming BaselWorld show, the Swiss watch brand Longines will reveal its new Twenty-Four Hours pilot’s watch.
In the 1950s Longines supplied watches to the Swiss national airline, Swissair. These watches, developed specifically for pilots, had a distinctive 24-hour dial. This feature met the needs of navigators who, at the time, had to determine the position of the aircraft and set up a flight plan.
Compared to the original, the remake features a slightly bigger date aperture locating at 3 o’clock, more contrast dial layout and its three hands are made of plain stainless steel, coated with Super-Luminova, while the “historic” watch featured hands made of gold. The onion-shaped winding crown is also a trifle larger. The modern Longines Twenty-Four Hours is fitted with caliber L704.2, a self-winding movement with hands that make one full circle of the dial in 24 hours. The stainless steel case has a diameter of 47.5mm; the dial is matte black with 24 white Arabic numerals coated with Super-Luminova and has a railway-track minute circle.

Besides a normal for this class of timekeepers sapphire crystal with double antireflective coating, there is also an engraved “hunter” back cover that protects the sapphire display back. The inside surface of the cover is engraved with the words “Re-edition of a Longines navigation watch exclusively made for Swissair navigators, 1953-1956“, plus the watch number. The Longines Swiss Watches Twenty-Four Hours is mounted on a black alligator strap and is water-resistant to 3 bar (30 meters).
