The A. Lange & Söhne 1815 is a tribute piece released in 2017 to honor the late Walter Lange, founder and re-founder of the company. The watch features a 40.5mm case crafted from either gold, platinum, white gold, or pink gold - all of which are polished to perfection. Inside is the beautiful hand-wound caliber L1924 movement which powers both subsidiary as well as sweep seconds hands. This movement can be stopped and started via a pusher at two o'clock on the dial. The design remains faithful to the classic A. Lange & Söhne style with its signature large date display, white enamel dial with Roman numerals and railway track chapter ring minutes indicator, blued steel hands, and small seconds subdial at 6 o'clock. The engraving on the balance cock reads "1815 - 2017", paying homage to Walter Lange's legacy. With its attractive styling, high-quality construction, reliable timekeeping accuracy, and unique history behind it - this watch is an ideal choice for someone looking for a beautiful tribute piece from A. Lange & Söhne that tells a story.
