Richard Lange was F. A. Lange’s eldest son who joined his father’s firm in 1868 as factory director, and like his father, he was a passionate watchmaker who sought to advance precision timing with mechanical finesse. During his tenure, the firm patented complications from split-seconds chronographs to dead-beat seconds timepieces, as well as patent number 9349 for an up/down power reserve indicator. In 1994 the firm was re-established by Walter Lange, great-grandson of the founder, with a collection of four wristwatches representing the company’s principles of craftsmanship, technical innovation, and modern design. As a tribute to Richard Lange, the firm in 2006 released a collection with his name featuring a time only wristwatch with center seconds, made in the four precious metals. Since that time, they have released other Richard Lange models including the limited edition Referenzuhr model in 2010 with 125 examples in platinum, and like the present model number 35, 75 pink gold wristwatches.

Like all A. Lange & Söhne watches, timekeeping and precision timing are part of their DNA going back to their founding in 1845. Their movements are known and appreciated by collectors for exacting craftsmanship and traditional watchmaking with a distinct identity. The Referenezuhr is a modern limited edition with a case and dial that fully displays the spirit and soul of A. Lange & Söhne. The 40.5mm diameter case is enhance by a clean dial with an oversized seconds dial at the 8 o'clock, and a smaller power reserve at 4 o'clock. The watch is powered by the caliber L033.1 with zero reset mechanism that is activated through the pushers at 2 o'clock , which resets the seconds hand to zero, thus allowing for extremely precise timing.

The present example, consigned by its original owner, is offered in outstanding condition, and accompanied by its international guarantee and presentation box.
