It is powered by the manual-wind caliber L951.5, which includes a column-wheel control, a flyback function, and a 60-hour power reserve. Unlike standard production 1815 models, this reference was never available for retail purchase, making it a one-of-one edition. While standard 1815 chronographs trade between $50,000 and $70,000, this specific commemorative piece is valued significantly higher due to its unique provenance and configuration.
