About the Langematik family
The Langematik of 1997 was Lange's first automatic watch of the modern era. It used a zero-reset function, so that pulling the crown sets the seconds hand back to zero for exact time-setting.
The Langematik Perpetual followed with a perpetual calendar and outsize date. The catalog lists pink gold and platinum references with caliber L922.1. Dealers check the calendar functions and ask for the papers and service history.
