A. Lange & Söhne Lange 1 Tourbillon Perpetual Calendar

Overall Condition: Outstanding condition overall. Case is in excellent condition. Dial is like-new. Factory strap shows only faint wear.

What you’re looking at is a variation of perhaps the most important wristwatch of the last 30 years.

The Lange 1 is without question the manufacturer’s flagship model, and the big date function is its hallmark. Though found in watches like the Zeitwerk or the Langematik Sax-O-Mat, it’s in the Lange 1 that it’s shown to the greatest effect. Alongside other details such as asymmetrical sub-dials depicting the hours and sub-seconds, and the A. Lange & Söhne signature with its famous ampersand, it shows a clarity of vision that is wholly Lange.

The Lange 1 has seen many variations, and this is perhaps the most impressive. At first glance, instantly recognizable as a Lange 1, this piece also flaunts a perpetual calendar display neatly incorporated to the existing design DNA, and a tourbillon hidden discreetly behind the dial.

Sized 42mm in rose gold, this Reference 720.032 is the result of tucking as much complication as possible into the framework of the Lange 1 design language. It's a brilliantly complicated and beautiful movement, and showcases the success of Lange's movement design to preserve the aesthetic of their collections. If you're looking for the most complicated Lange 1 on the market but want to maintain a discreet low profile, this is the perfect watch for you. The tourbillon hides on the caseback, but the opulence and quality of this piece is visible from across the room. A masterpiece of the highest order, this watch is truly something special in all its Teutonic splendor.
