Although undoubtedly one of the top models from the Heritage collection by Longines, Weems Second-Setting Watch is closely connected to the previously covered Lindbergh Hour Angle timepiece by the Swiss manufacturer. It is inspired by the invention of Captain Philip can Horn Weems, the pioneer of navigation who was assigned by the Navy to teach Charles Lindbergh navigation with the use of stars. In a way, this model can be considered as a simplified and stripped-down version of the Lindbergh timekeeper, especially since it shares some of its features such as its dimensions, type of self-winding caliber, rotating central dial, as well as a device that was designed by Weems which allows the synchronization of the second hand with the use of radio signals.
The watch that reinterprets the famous Longines model made in the collaboration with Weems in 1929 was designed as a pilot’s tool. Its ability to synchronize the second hand with the use of radio signal was very useful to the aviators because it allowed the effortless adjustment of the watch with the time on the plane’s chronometers. This was very convenient since even the minutest of errors can lead to wrong calculations, which is far from acceptable for such precise operation as it is flying a plane. The aeronautical heritage of the product is also visible in the use of oversized ball-shaped crown that can be operated even while wearing gloves. The list of complications and technical ingenuity used in this model continues with the rotating bezel that adjusts to daily variations of the equation of time.
The beating heart of Weems Second-Setting timepiece from the Heritage collection is an automatic high-frequency mechanical caliber L699 that stores about 46 hours of power reserve. The caliber made from modified base movement ETA A07 111 incorporates 24 rubies. If you are interested into checking out how the mechanical caliber functions, it is possible to get a glimpse through its transparent case back. It gets even cooler, since the see-through back is only visible when you remove the cover with engravings. The shape of the case is circular, while its width is 47.5 mm.
Stainless Steel or Pink Gold
High-end appearing face of the watch is protected with sapphire crystal with several coatings that nullify the harmful effect of reflection of the light on the legibility. Its dial with a rotating central segment is white colored, and it is lacquered and polished. It is completed with painted numerals and Breguet-styled blued steel hands. The overall construction of the watch makes it water proof to 30 meters.
There are two slightly different versions of Weems Second-Setting timekeeper from the Heritage collection of Longines Watches. The first one is made with a stainless steel case and sports Arabic numerals on the dial, while the second one combines 18K pink gold with Roman numerals. In each case, the watch is paired up with a brown alligator strap with contrasting stitches that fasten with a buckle.
