The moon phase display of the new GRAND LANGE 1 MOON PHASE occupies a prominent position on the main dial, which can accurately run for 122.6 years. The patented coating of the moon phase disc brings a lifelike shape to this astronomical complex, striking. The moon is a fascinating celestial body. Since ancient times, the moon has taught countless astronomers. It affects tidal effects, climate stability, and the laws of life of many organisms and plants. Because of this, many watch enthusiasts have a crush on the moon phase display. Since the return of Lange’s reputation, the Saxony brand has launched no less than twelve watches with moon phase display. However, the moon phase design of the new GRAND LANGE 1 MOON PHASE is the most eye-catching ever. This astronomical display has a large space on the main dial and is connected to the hour wheel, so it can closely follow the actual trajectory of the moon, and constantly move like the moon. The increase is very subtle and difficult to detect with the naked eye.
In addition, the moon phase display reproduces the time between two new moons with an accuracy rate of 99.9978 percent. The average length of the new moon is 29 days, 12 hours, 44 minutes and 3 seconds. For simplicity, typical moon phase displays mostly reduce this period to 29.5 days, causing a deviation of 44 minutes and 3 seconds for each lunar month, and within a short period of two and a half years, an entire day of error will form. Fortunately, the seven-gear transmission of GRAND LANGE 1 MOON PHASE has more accurate calculation capabilities, which makes the deviation of each cycle less than one minute. If the settings are correct and the watch is always running, the moon phase display will only need to be adjusted for one day after 122.6 years. Assuming that the watch has not been wound for a long time, the wearer can also adjust the display at any time by pressing the buttons on the outside of the case (between 7 and 8 o’clock). Lange’s product R & D personnel are committed to making a solid gold moon phase disk coating, which fully reflects the brand’s spirit of perfection. When depicting the night sky, image truth is the primary goal. After in-depth research and development, the brand finally obtained patented coating technology, showing brilliant colors.
And clear texture details to achieve the highest aesthetic standards. The interference effect caused by the overlapping of light waves cancels out all the non-blue spectrum of incident sunlight, and presents a clear blue scene in front of the viewer. Then, the watchmaker will use laser to cut out more than 300 stars of various sizes and sharp lines to form a miniature galaxy world.
GRAND LANGE 1 MOON PHASE combines the eccentric dial, large calendar display and the perfect movement made by the watch factory, to capture the characteristics of Lange’s most famous watch series. A power reserve of up to 72 hours is propelled by a mainspring alone, making the movement less than 4.7 mm thick. The delicate case is available in rose gold, yellow gold and platinum, with a diameter of 41.0 mm. The Lange-made L095.3 caliber combines all traditional functions, including classic screw balances, balance springs independently developed by Lange, 3/4 plywood made of untreated German silver, and hand-crafted The movement components allow global connoisseurs to appreciate the watchmaking technology and precision technology of Saxony while taking a closer look at Lange watches.
