SEEN THROUGH A WATCHMAKER’S LOUPE (3 MB)

THE DATOGRAPH PERPETUAL BY LANGE.

This masterpiece by Lange was the first wristwatch that incorporates a chronograph and a perpetual calendar. It no doubt represents the most classic combination of complications, capturing the moment, the present, and eternity. Additionally, it is endowed with all of the fea-tures that make Lange timepieces so distinctive. It owes its harmoni-ous personality to the subtly offset symmetry of the solid-silver dial.

The DATOGRAPH PERPETUAL

IN 122 YEARS, THE DATE MUST BE CORRECTED BY ONE DAY.

The DATOGRAPH PERPETUAL can stop times of up to 30 minutes
with an accuracy of one-fifth of a second. The precisely jumping minute counter provides unmistakable readings. With a single press
of a button, the flyback function allows the chronograph to be reset and restarted instantaneously during an ongoing time measurement. The perpetual calendar displays include the day of the week, the month, leap years, a day/night indication, the moon phase and the outsize date. The latter deserves to be called a "perpetual outsize date" because it remains accurate until the year 2100; only then must it be manually advanced by one day. The first correction of the highly precise moon-phase display, also by just one day, falls due in 122 years.

The DATOGRAPH PERPETUAL

A PERFECT MICROMECHANICAL MICROCOSM.

All displays of the perpetual calendar can be individually adjusted with push pieces recessed in the case or collectively advanced with a main push piece. To prevent this from happening inadvertently, the watch is fitted with an interlock device that only allows the collective switching of the displays when the crown is pulled. The DATOGRAPH PERPETUAL is available exclusively in platinum with a hand-stitched crocodile strap, or with an exquisite platinum bracelet.
