1815 Rattrapante Perpetual Calendar

A. Lange & Söhne goes further still in its command of short times with the 1815 Rattrapante Perpetual Calendar and its eighth in-house chronograph calibre. Here, the chronograph is joined by a perpetual calendar with hands which alone accounts for 100 of the total 636 movement parts. Visible through a sapphire crystal back, it reveals the exceptional level of finishing by the Saxon watchmaker, as well as the extraordinary movement construction.
