Up for grabs is an A. Lange & Söhne Langematik Perpetual Ref. 310.026E in 18k white gold.
Housed in a 38.5mm case, the Langematik Perpetual was the first mechanical wristwatch to combine a perpetual calendar with Lange’s signature outsized date. The calendar automatically accounts for varying month lengths, including leap years.
The watch remains unpolished and presents with only light signs of wear consistent with an 11-year-old piece. The original caseback sticker is still intact, suggesting relatively limited use.
It is fitted on its original strap and Lange folding clasp.
Accompanied by its original Lange winding box, manuals, and warranty papers dated December 2015.
No service history is known, though the watch is running and functioning as it should.
