Top 10 Technically Important Mechanical Wrist Watches watch talkThe Navigational WatchIn 1919, three planes attempted to fly cheap watches from Newfoundland to London, only one of them made it. It was after witnessing this tragedy that one of the fathers of modern navigation, Captain Philip Weems of the U.S. Navy, was driven to improve methods of flight navigation.It was not possible to use the same methods employed by seafarers so Weems set about devising new tools and navigational techniques.Chronometric precision android tablet was rare back then but accurate time reading was crucial because with the high speeds and long distances involved, to be off by even just a few seconds, could prove catastrophic.To solve this problem Weems came up with an ingenious solution: the Second Setting Watch. Since no watch could adjust the seconds hand to the dial, Weems solution was to adjust the dial to the seconds hand. To achieve this he created a movable dial marked with 60 second increments and consequently Ainol NOVO7 Legend enabled a navigator to read truly accurate time.The second part of what was to become the "Weems System of Navigation", was the invention of a modified sextant to be used when the horizon wasn't visible. Aviators in the 1920's and 30's were now able to navigate with much greater accuracy and fly with less risk by using Weems system.Top 10 Technically Important Mechanical Wrist Watches watch talkIt was Longines' involvement in aviation - they were official timers for the first solo flight across the Atlantic in 1927 - that was ainol tablet PC to lead to a partnership with famous aviator Charles Lindbergh to create the Hour Angle watch, a derivation of the Weems watch.Lindbergh wanted to push Weems' idea of a navigational watch still further. He was concerned about the problem of determining the plane's bearings during flight and put forward the idea of a watch that also gave you the 'hour angle' in degrees and minutes, enabling you to calculate longitude. Lindbergh was so convinced his idea would be a valuable aid to pilots that he even provided sketches to Longines. Longines were enthusiastic and a patent was filed in October 1931 for the Digital Photo Frame Longines Hour Angle with rotating bezel.The first version used a hand-wound pocket watch movement and had an extra long leather strap so it could be worn over thick flight jackets, and an extra large crown for winding it with gloves on. In 1938 Longines released a second improved version. Following its introduction, and up until the intervention of WWII, the Lindbergh design performed an important role in the setting of a number of new aviation world records.The Weems Second Setting Watch and the Lindbergh Angle Hour Watch are both milestones in the development of pilot's watches as well as being important navigational aids up until they were wholesale watches made obsolete by electronic navigational equipment. Longines produces authentic recreations of both these watches.The Date Calendar WatchAfter telling the time, the next most important addition to a watch would be the date. Add in a perpetual calendar and you would have all the fundamentals covered.Launched in 1945, The Rolex Datejust was the first wristwatch with a date function. 745TDBanty 130723
