The main assets of the new A. Lange & Sohne watch are a fusee-and-chain transmission and a tourbillon mechsnism, incorporated into the structure of the brand’s proprietary hand-wound calibre L072.1 movement. Largely embellished and assembled by hand, the latter is adjusted in five positions. Integrated within the movement are a three-quarter plate made of untreated German silver, and the fourth-wheel bridge, engraved by hand.
Composed of 636 parts, including the chain and 32 jewels, the caliber runs at the rate of 21,600 vibrations per hour and supplies a 36-hour power reserve. It also incorporates a shock-resistant Glucydur screw balance and a high-quality balance spring, produced in the brand’s workshops. The caliber finds its natural home in a 41.9mm honey-colored gold case.
The new A. Lange & Sohne Richard Lange Tourbillon Pour le Merite Handwerkskunst watch is adorned with a solid honey-colored gold dial, engraved by hand. It indicates hours, minutes and subsidiary seconds. The one-minute tourbillon mechanism is allied with a patented stop seconds. The display is protected by a sapphire crystal, hardness 9. The same glass is used for the case-back.
Issued in a limited edition of 15 pieces, the new A. Lange & Sohne watch is attached to a hand-stitched crocodile strap in red-brown. It is secured to the wearer’s wrist by means of the Lange deployant buckle, made of solid honey-colored gold.
