A. Lange & Söhne, Glashütte i/SA, "1815 TOURBILLON", Movement No. 113744, Case No. 216235, Ref. 730.032F, Cal. L102.1, 39,5 mm, circa 2015 A Glashuette wristwatch in mint condition, with visible one-minute tourbillon regulator - with original box, operating instructions, Lange-booklet and Lange-guarantee seal dated April 27, 2015 Case: 18k pink gold, sapphire glass screwed on back, "Lange" 18k pink gold deployant clasp. Dial: solid silver, argenté, window for tourbillon cage. The Model 1815 TOURBILLON was introduced in 2014 and was the first timepiece created by A. Lange & Söhne to combine the patented second stop function for the tourbillon with the ZERO-RESET function. When the crown is pulled, the seconds hand instantaneously moves to zero and remains there; this means that the watch can easily be set and restarted with one-second accuracy. The dial features the typical style elements of the 1815 family, which bring to mind the design of vintage pocket watches: blued steel hands to stand out from the dial, Arabic numerals, sunk centre and railway-track minute scale. Case: as new. Dial: as new. Movm.: as new, capable of running, cleaning recommended.
