The Longines Twenty-Four Hours watch is a tribute to the original model made for Swissair navigators in the 1950s. It features a self-winding movement that allows the hands to make one full circle of the dial in 24 hours. The 47.50 mm stainless steel case houses a matt black dial with 24 white Arabic numerals coated in Super-LumiNova for easy reading. The watch also has a railway-track minute circle, date aperture at 3 o'clock, and a sapphire glass covering the dial. With a black alligator strap and water resistance of 3 bar, this timepiece is both stylish and practical. The transparent caseback reveals the intricate details of its Longines calibre 37
