The 1815 Rattrapante Perpetual Calendar combines two complications Lange normally keeps separate: a split-seconds rattrapante chronograph and a perpetual calendar with moon phase. Because it tracks the full leap-year cycle rather than just 30/31-day months, the calendar does not need correcting until the year 2100. Caliber L101.1 is built from 636 parts and fills a 41.9mm platinum case.
- The perpetual calendar display also carries a leap-year indicator, alongside the split-seconds chronograph and moon phase.

Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
