LANGE 1 PERPETUAL CALENDAR Developed with the passion for doing things differently
The new LANGE 1 PERPETUAL CALENDAR is totally focused on the eponymous complication . Its integration into the prominent dial layout of the LANGE 1 was made possible thanks to a peripheral month ring created especially for this design . The new timepiece comes in pink gold with a grey-silver dial or – in a limited edition of 150 watches – in white gold with a solid pink-gold dial . The moonphase display with an integrated day / night indicator is a further special feature .
Exactly 20 years ago , A . Lange & Söhne presented the LANGEMATIK PERPETUAL , its first wristwatch with a perpetual calendar . It was followed by seven further models , mostly in combination with other complications such as a chronograph , a tourbillon or both .
The perpetual calendar reconceived
Apart from the classic principle with calendar displays controlled by a 48-step cam , the LANGE 1 TOURBILLON PERPETUAL CALENDAR introduced in 2012 already took a different approach that has now been adopted by the new model . To integrate the calendar ensemble into the exceptional off-centre dial architecture of the LANGE 1 without compromising the harmonious balance of the displays , the month indication was implemented with a ring at the periphery of the dial that advances once a month . This design replaces the classic control principle with a 48-step cam . The innovation challenged the ingenuity of Lange ’ s engineers because advancing the ring at the end of the month requires considerably more power than traditional solutions .
