Richard-Lange-Tourbillon ‘Pour-le-Mérite’-and its early blueprints
93This watch number 93 is based on the design of Richard Lange Tourbillon ‘Pour le Mérite’. Watches with unique timekeeping performance are a model of sophisticated mechanical structure and a contemporary interpretation of Seyffert’s perfect pursuit of watchmaking. When connoisseurs admire Richard Lange Tourbillon “Pour le Mérite”, the first thing that catches the eye is the overlapping eccentric dial time circle: the large minute circle placed above is the main part, with an elegant posture, gently overlapping and distributed vertically Second and hour dials with relatively small areas on the left and right of the central axis. The dial layout is derived from 18th-century precision timepieces.In addition to serving as a timekeeping service and chronometer calibration, it is also used by manufacturers to synchronize time for new watches. To prevent it from being difficult to read when there is insufficient light, the hour and minute hands are mounted on different dials.
Lange launches Richard-Lange-Tourbillon- ‘Pour-le-Mérite’ rose gold version with extreme precision
LangRichard Lange Tourbillon “Pour le Mérite” has a circular cutout on the dial of the second hand, which is penetrated by the minute scale above and the embedded tourbillon bridge, and the tourbillon frame is now in it. However, the details of the tourbillon can only be fully revealed between 12 and 6 o’clock. Once at 6 o’clock, the dial engraved with Roman numerals VIII, IX and X instantly turns into the display window to complete the hour operation. This operation is driven by a precise switching device to ensure that the dial area rotates 90 degrees every 6 hours, and the time display is equally clear regardless of day and night. At 12 o’clock, the hour hand dial area disappeared quickly, and in the next 6 hours, with the tourbillon rotating and reciprocating at the same time, and present again. This performance is to offset the deviation caused by the gravity of the balance on the balance shaft. With the patented stop-second device, the tourbillon can be stopped by pulling the crown, and the time display of the watch can be adjusted with the accuracy of seconds. The diamond end stone bearing on the edge of the bottom of the watch is fastened by a screw-fixed gold sleeve. This distinguished and exquisite design marks Lange’s famous ‘1A’ premium pocket watch quality mark.

Humboldt was founded in 1842 to reward the outstanding achievements of the scientific and artistic world. A Lange watch that can be dubbed ‘Pour le Mérite’ must be a complex piece equipped with a unique sesame chain drive system. The watch cleverly uses the principle of leverage to balance the gradual weakening of the power of the mainspring under continuous use, while maintaining the torque, so that the amplitude of the balance wheel remains stable during the 36-hour power reserve time. In addition, the planetary gear system ensures that even when the watch is wound, its constant power transmission will not suffer any interference. The wide 3/4 plywood opening position allows you to see the details.
