A. Lange & Söhne Launch Most Complicated Watch of its Lange 1 Anniversary Series

After revealing the Lange 1 “25th Anniversary” prior to this year's SIHH watch fair, followed by the Grand Lange 1 Moon Phase and Little Lange 1 over the last couple of months, the watchmaker has debuted the fourth in a series of commemorative watches.

Called the A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar “25th Anniversary”, it is the most complicated and exclusive model of the family and will be limited to just 25 examples. 

Boasting a 25th-anniversary theme, the limited edition commemorative timepiece is powered by the in-house L082.1 self-winding movement made of 624 parts. 

The tourbillion is hidden and can only be observed from the back, while it also boasts an ingenious perpetual calendar with big date and a peripheral months indicator, along with a tourbillon and automatic winding.

Nevertheless, all of the recognisable visual elements of the 1994 Lange 1 have been preserved, including its signature display with off-centered hours and minutes, odd placement of the small seconds and the emblematic outsize date. 

All the anniversary models have a solid silver dial with rich blue highlights, and the Lange 1 Tourbillon Perpetual Calendar “25th Anniversary” is no exception. 

The other elements that help it distinguish it from the standard version include an anniversary engraving on the balance and tourbillon cocks and the hand-engraved, white gold moon phase disc, which is also found on the anniversary moon phase. 

The limited edition is priced at $361,500.
