The new A. Lange & Söhne 1815 Rattrapante Perpetual Calendar, with its 18K white gold case and gorgeous pink gold dial (salmon colour), combines three of the most complex watchmaking complications in a classic design. The equally rare and ambitious split-seconds chronograph or combination of a split-seconds chronograph and a perpetual calendar is now presented with a stunning rose gold dial.
Launched for the first time in 2013, the Lange 1815 Rattrapante Perpetual Calendar marked a milestone in the brand’s renaissance history, after at least seven chronograph movements had been made in the Saxon factory. Equipped with a specially developed movement, it incorporates three of the most complex complications while maintaining the classic, elegant design of the 1815 high quality copy watches collection.
The dial of the A. Lange & Söhne 1815 Rattrapante Perpetual Calendar in white and rose gold sets the standard for elapsed time measurements and calendar cycle displays. In addition to the traditional functions of a chronograph, this complication is also capable of measuring intermediate and comparative times, as well as determining the minimum and maximum values within a minute. Since the balance wheel of the in-house movement L101.1 oscillates six times per second, it is possible to record stopped times with an accuracy of one-sixth of a second. High-precision readings are ensured thanks to the extra graduations on the peripheral minute scale.
The precisely arranged processes within the movement can be observed through the sapphire crystal case back. A classic two-column-wheel transmission is used to control the measurement of stop times and intermediate times. As is typical of Lange, complex technology is combined with a high degree of craftsmanship. All moving parts have a straight-grained upper surface and polished perimeter chamfers. Only an experienced polisher is capable of polishing bevels to sharp and flat perfection.
The Lange L101.1 movement consists of 631 independent parts. The perpetual calendar device alone requires 211 parts, and the split-second timing device requires 206 parts. The movement offers a 42-hour power reserve. luxury copy Watches
The design of the high-precision moon phase display also takes long-term development into consideration. It so accurately simulates the duration of Earth satellites’ conjunction orbits that it takes 122.6 years to correct the display for one day. While the split-seconds chronograph is capable of measuring different time intervals to a fraction of a second, the extraordinary technical feat of the perpetual calendar lies in its ‘long-term memory’. As its name suggests, this complex and prescient mechanism ensures the correct display of the date, day of the week and month – every day for decades, even taking leap years into account. The calendar display can only be corrected by one day, but no later than March 1, 2100; according to the rules of the Gregorian calendar, leap years are skipped.
What makes the A. Lange & Söhne 1815 Rattrapante Perpetual Calendar unique is not only the technical details, but also the orderly arrangement of its displays. Following the Datograph Perpetual Tourbillon in 2019 and the Lange 1 Perpetual Calendar in 2021, the new 1815 Rattrapante Perpetual Calendar is Lange’s third timepiece with an 18K rose gold dial, a warm golden tone that contrasts sharply with the elegant and cool white gold dial Shell diameter 41.9 mm, thickness 14.7 mm.
The dial adopts the traditional railway track minute scale, Arabic numerals and the harmonious arrangement of four small dials, reflecting the essence of the watch family named after the year of Ferdinand Adolph Lange’s birth. The multiple displays of the perpetual calendar and split-seconds chronograph echo the classic aesthetics of early Lange pocket watches. Two pairs of combined calendar indicators are arranged at 3 o’clock and 9 o’clock respectively. The small dial on the left shows the date and day of the week, and the small dial on the right shows the month and leap year. The moon phase display shares a subdial with the small seconds at 6 o’clock in expressive colour. Minute counter and power reserve indicator at 12 o’clock. A shorter gold hand on the inner ring shows when new power needs to be supplied to the movement via the winding crown. Longer hands in blued steel provide information about the stopped minutes.
