A. Lange & Söhne presents a one-of-a-kind version of the 1815 Chronograph called the "Hampton Court Edition," which will be auctioned off later in the year to help support the efforts of The Prince's Trust. Featuring a 39.5mm 18-carat white gold case, the watch features a silver and black dial with sandstone-colored dial elements. Inside the watch is Lange's own calibre L951.5, a manually-wound movement that has a 60-hour power reserve when fully wound. The movement can also be viewed via a sapphire crystal caseback, which is hidden under a hand-engraved hinged cuvette.
The 1815 Chronograph "Hampton Court Edition" will go on sale on November 6th at the Geneva Watch Auction XVI and proceeds will benefit The Prince's Trust.
