Longines 24-hour Dial Watch Introduction

In the 1950s, Longines supplied watches for Swissair, Swissair. These timepieces, specially developed from the brand’s pilot watches, have a unique 24-hour dial. Aircraft navigators at the time had to determine the plane’s location and make a flight plan, and this technical feature of the watch fulfilled these needs. Due to its historical significance and outstanding functions, Longines is now re-launching this watch, but also because of its enduring aesthetic appeal. This new product is named the 24-hour watch.
 In 2009, Harry & Middot; Hoffmann, a retired Swissair pilot, visited the Longines Museum. He took this opportunity to give a Longines watch he had worn while working at SWISS to Longines. This watch with a 24-hour dial is one of Longines’ series of timepieces specially designed for SWISS aircraft pilots in the 1950s.

 In the aviation industry in the mid-twentieth century, one of the duties of aircraft navigators was to determine the location of aircraft and develop flight plans. Therefore, a reliable watch becomes a must-have for pilots. Airplanes need to travel through different time zones on the way back and forth, and sometimes the sun is not visible, so the sun cannot be used as a reference point, so an instrument is required to accurately display the time of day. With a 24-hour dial, the pilot overcomes this problem.

 Harry & middot; Huffman served as the navigator of SWISS, flying DC-4s, DC-6s, DC-7s, DC-8s and Coronados until 1974. The watch was produced by Longines exclusively for Swiss National Airlines in the early 1950s. The watch is engraved with the number 8233331. It is equipped with a Longines 37.9N movement and a central seconds hand. This was in the 1940s. Designed in the 1950s and used in Longines specially made for pilots. The stainless steel case back of Mr. Huffman is engraved with the Swissair brand logo. Longines archives show that this is one of the 70 limited edition watches produced exclusively for Swiss National Airlines between 1953 and 1956. These watches are technically in the same vein as Longines pilot watches. They are Longines Whistles seconds hand-set watches produced in 1927 and Longines continuous time angle watches produced since 1932. As a professional Swiss watch company, Longines chose to re-launch this watch because of its historical significance and excellent functions, and also because of the enduring aesthetic appeal of this work, this watch was named Longines. 24-hour watch.

 The Longines 24-hour watch is equipped with a movement L704.2, an automatic movement with hands moving around the dial every 24 hours. The diameter of the stainless steel case is 47.50 mm; the dial is matte black with 24 white Arabic numerals, coated with ultra-bright luminous paint, and has a rail-shaped minute scale ring.

The sapphire crystal protects the dial, and this watch also has a transparent case back. Open the cover of the case back and you can see the movement of the movement.
