About the A. Lange & Söhne 1815 Rattrapante
The 1815 name pays homage to the birth year of Ferdinand Adolph Lange, the watchmaker who established the Saxon tradition of fine watchmaking in Glashütte, Germany. The rattrapante, or split-seconds, complication allows a chronograph to time two simultaneous events independently — a function requiring extraordinary movement architecture and finishing discipline. Within this line, the 1815 Rattrapante Perpetual Calendar elevates the challenge further by integrating a perpetual calendar that accounts for leap years and month lengths without requiring manual correction for decades. These are watches offered in precious-metal cases — platinum and gold — befitting the complexity and hand-finishing labor they represent.
What to Look For
Buyers should distinguish between the standard 1815 Rattrapante, such as the platinum 425.025, and the grander 1815 Rattrapante Perpetual Calendar references (421.025FE in platinum, 421.056FE in white gold, and 421.032FE in pink rose gold), as the perpetual calendar adds significant complication and typically commands a higher market position. Case material plays a meaningful role in value, with platinum examples generally commanding a premium over yellow or rose gold, and limited or special editions — often denoted by an FE suffix indicating Handwerkskunst or special production variants — carrying their own collector premiums. Condition, box, and papers are critical factors when buying a pre-owned Lange at this level.
Frequently Asked Questions
What is the difference between the 1815 Rattrapante and the 1815 Rattrapante Perpetual Calendar?
The standard 1815 Rattrapante, such as reference 425.025 in platinum, focuses solely on the split-seconds chronograph complication. The Perpetual Calendar versions — references 421.025FE, 421.056FE, and 421.032FE — add a perpetual calendar that automatically tracks the correct date, day, month, and leap year cycle, making them among the most complex watches in the entire Lange catalog.
