Lange is a German watch. Each one of the Lange watches are unparalleled superb technology and a high level of perfect hand-crystallization, the market's attention. How to identify the authenticity of Lange watches has always been a topic of great concern to everyone, then Xiaobian to share the authenticity of the Lange table authentication method. Lange watches are hand-carved, hand-dipped, each watchmaker at least 3 to 7 years of study before they really began to participate in the production of watches and clocks. Normally every Lange watch is made for a minimum of 6 months and often takes 8 to 10 months to complete. Therefore, Lange table production is very limited, every year about 5000 or so. Now we all know from the watch details, unique authenticity. unique design 1. Design from the identification All along, the goal of Lange watchmaking is to create timekeeping instruments with excellent features. Ferdinando? Adolph Lange devoted himself to the search for the "perfect watch" all his life. Until today, watchmakers are still determined to improve the accuracy, clarity and readability of their timepieces when making each watch. Lange watches are by no means limited to the pursuit of perfection techniques, all movements must achieve the highest aesthetic level expected. Each timepiece also incorporates unique, traditional elements such as carved balance spikes, screw-on gold sleeves and cleats made of untreated German silver. 2. Identification from the watch parts All Lange movement and quality-related parts, are manufactured by the Lange Watch Factory. First, part production includes making unfinished splints, bridges, levers, clockwork, gears and pinions. Next, the drill and edge of all the components are finely manned, which requires high-precision optical measurements: hundreds of holes are scanned on the main plate alone, which can be confirmed with an accuracy of ten thousand millimeters. Lange 's movement is a collection of high-performance mechanical essence, contains hundreds of components. Each component must be calibrated to the most accurate standard to ensure the accuracy of a fully assembled watch. To meet this high standard of precision, Lange watchmakers use modern grinding and wire cutting machines to create extremely precise parts. In the manufacturing process, the watchmaker repeatedly check whether the finished product meets the strict standards. For example, a splint may need to be machined more than ten times until all the recesses are flush, hole penetration and thread appearance will be completed. Glashütte sun pattern 3. From the watch modification and carving identification Watch connoisseurs will be able to identify a Lange movement. Whether viewed through the sapphire crystal back, each part is modified in a specific way. And, regardless of size, each part must meet rigorous process and aesthetic standards. Simply completing a flawless planar polishing process takes months to practice. Cutting edge processing stress cuts edge with a unified point of view and width. The balance wheel adopts a special modification process, Engraving Langer- style floral motifs above the splint makes each Lange watch unique. Glashütte diamond pattern uniform line decoration 3/4 splint and movement back side of the bridge. The process is based on the rolling wheel along the surface of the workpiece diagonal rolling parallel ruled. Spiral lines of the Glashütte sun are mainly used to decorate the main barrel and other circular surfaces or gears. This texture is based on the grinding wheel along the opposite direction of rolling parts formed. 950 platinum case 4 from the material identification Lange insists on producing only the "best watch in the world," thus limiting its annual production to thousands of pieces, all using only gold or platinum casework. From the double assembly process of each timepiece, unparalleled craftsmanship and decorative arts can be seen, its work is indeed extraordinary. Since returning to the 90's in the 20th century, Lange has developed 43 home movements that provide an uninterrupted power to his outstanding work. 5. From the watch assembly identification During the first assembly, do hundreds of parts that focus on complex parts of the movement operate smoothly. Although the features of these components are flawless at this stage, all the movements need to be disassembled and cleaned after the first assembly. Because no matter how cautious, all the parts have the opportunity to be slightly scratched in the calibration process, or the movement into small dust. After cleaning, many parts are decorated, carved and polished using traditional techniques. This second assembly process takes time and is extremely rare in the field of watches, yet every Lange watch must be so. Lange watch is very precise, each watch is unparalleled superb technology and a high standard of perfect hand-crystallization. They are hand-carved, hand-polished, each watchmakers need at least 3-7 years of study before they really began to participate in watchmaking . Lange watches from the subtleties can distinguish between true and false.
