Lange DATOGRAPH PERPETUAL combines chronograph and perpetual calendar, the noble contrast between white 18K gold and gray. This masterpiece combining flyback chronograph and perpetual calendar, with solid white 18K gold case and gray dial, is accurate and Elegant coexistence.
For André Gide, a French writer of the Nobel Prize in Literature, gray is the hue of truth, which has nothing to do with its balance and charming glory. In DATOGRAPH PERPETUAL, the white 18K gold case and gray dial reflect these two qualities. Since 2006, the name of this watch has been ingeniously linked to the flyback chronograph and perpetual calendar. This watch is equipped with three extremely sophisticated cutting-edge technology devices, which give full play to the accurate performance of short-term timing: the column wheel helps to reliably control all timing functions, the precise jumping minute indicator can always display a clear stop time, and the flyback system is Can quickly and accurately measure time periods for different projects.
The perpetual calendar combined with the Lange large calendar, day of the week, month and leap year is very accurate, and it is not necessary to adjust the day until 2100. Convenient quick correction buttons allow all perpetual calendar displays to advance simultaneously. As for the three hidden correctors, each display can be adjusted individually.

The dial’s dark gray tone accentuates the display, contrasting strongly with the dark blue moon phase dial with gold stars. Since the first introduction of 18K rose gold in 2010, the contrasting design has been one of the characteristics of DATOGRAPH PERPETUAL, this time with 18K yellow gold rhodium-plated rod-shaped hour markers, hours and minutes. The chronograph hands show stop times accurate to one-fifth of a second and are made of blue steel. The integrating dial and second hand are also made of the same material, which is particularly striking on the silver-grey background of the small dial. The movement, composed of 556 fine parts, further confirms the exquisite skills of the Lange watch factory in Saxony in the field of complex watchmaking devices.
