DATOGRAPH PERPETUAL

Precision in the long and short run

The DATOGRAPH PERPETUAL is the first wristwatch for which Lange combined a chronograph with a perpetual calendar. Showing the date, day of week, month, and leap year, this perpetual calendar is engineered to such accuracy that it requires no adjustment until the year 2100, when a one-day correction is needed. The chronograph function allows short-time measurements with an accuracy of one-fifth of a second.

In the DATOGRAPH PERPETUAL timepiece in white gold, Lange combines a chronograph and a perpetual calendar in a single wristwatch.
The perpetual calendar of the DATOGRAPH PERPETUAL timepiece in white gold requires no adjustment until the year 2100, when a one-day correction is needed.

The calibre L952.1 movement consists of 556 parts – the calendar mechanism alone incorporates 223 components. The chronograph mechanism is controlled by a classic column wheel that coordinates all switching sequences. Rockers and levers of various shapes engage with this wheel. The considerable length of the levers is due to the special dial arrangement. They bypass the outsize date mechanism and bridge the distance to the subsidiary dials located below the centre line.
