A. Lange and Söhne Datograph 403.025

Conservatively excellent to near mint condition Lange Datograph in Platinum complete with box and papers on original Lange strap with original Lange tang platinum buckle. (Strap in very good condition.) US$42,000 shipped to continental US. This is my personal watch. I purchased it from the original owner in early 2010. It received a complete Lange authorized service in late 2009.There are no issues with the watch whatsoever. It has been a joy to own. A revolutionary idea in the manufacturing & operation of mechanical chronographs. This watch features: Black colored solid silver dial with Applied Roman Numeral & Index Hour Markers. Patented large double window date display located at the top of the dial with quick correction button located on the case edge at the 10 o'clock position. Chronograph movement with flyback function - allowing the stop-watch to be instantaneously restarted for continuous timing, without having to stop, reset and then restart the chronograph. Furthermore the minute hand of the chronograph jumps in 1 minute increments rather than continuously moving - this allows for accurate reading of the timing function. The movement has 40 jewels & beats at 18,000 vph. The movement has an approximate power reserve of 36 hours.
