Presenting one of the most advanced pieces of haute horology ever created, this breathtaking A. Lange & Söhne combines a perpetual calendar with an orbital moonphase that is so precise it won’t deviate by a full day for more than a thousand years. Its movement finishing is pure Saxon artistry with hand-engraved bridges, flawless chamfers and a three-quarter plate that shows off its 14-day constant-force caliber. Incredibly rare and produced in very small numbers, this is a trophy-level masterpiece for collectors who want the apex of mechanical watchmaking. This watch presents in excellent condition, with little to no signs of wear. Please reference the photos for the most accurate representation of the condition of the watch. We do our best to emphasize, rather than diminish any flaws through our macro photography. This timepiece comes as a complete set with its inner box, outer box, and warranty booklet. Due to the high value of this timepiece, it will be delivered to you by armed guards.
