Introduced in 2011, the Richard Lange Tourbillon Pour le Mérite was launched in white gold, pink gold, along with two limited edition variants with 15 pieces for Handwerkskunst honey gold and 100 pieces in platinum. Inspired by the precision chronometer No. 93 pocket watch crafted by principal pioneer of Saxon watchmaking in the 18th century, Johann Heinrich Seyffert, the A. Lange & Söhne Richard Lange Tourbillon Pour le Mérite reflects Seyffert’s quest for horological perfection with an impressive contemporary interpretation by the brand.

The first feature connoisseurs would notice is the ensemble of three overlapping circles on its argenté silver dial. Balancing in harmony, each circle devotes itself to the utmost degree of accuracy, starting with the dominant element of a large minute circle taking the lead at the top hovering over the two smaller subdials for seconds from the left, and hours indicated with Roman numerals on the right. At the intersection of the lower subdials, a remarkable feature enables a splendid unobstructed view of the one-minute tourbillon rotating in its full glory. Patented as a pivoting dial with a hidden segment, the Roman numerals VII, IX and X are set on a separate dial segment that will pivot instantaneously into the aperture to complete the hour scale between 6 and 12 o’clock. The motion is generated by an ingenious switching mechanism, which assures that the dial segment is advanced by 90 degrees in increments of six hours. Coupled with a patented stop-seconds mechanism, the tourbillon can be halted simply by pulling the crown, allowing the time displayed by the watch to be set to one-second accuracy.

This model in white gold features an argenté-coloured dial crafted from solid silver and was only available at A. Lange & Söhne boutiques. Preserved in excellent condition, the present watch is furthermore accompanied by its A. Lange & Söhne Guarantee dated February 11, 2018, product literature, presentation box and outer packaging.
