In a time where collectors are regaining interest in horological creations off the wrist, it only makes sense that a clock watch would set a new record at auction.

A rare A. Lange & Söhne timepiece from 1916 just hammered down for a cool $2.06 million (1.59 million CHF) at Sotheby’s auction in Geneva this week. That price tag makes the memento the most expensive piece from the watchmaker to ever sell at the block.

The 18-karat pink-gold beauty (a.k.a. Watch No. 62508) comes in at No. 5 out of nine Grande Complications brought to life by A. Lange & Söhne, and the final example to be done up in the striking pink material. As the name suggests, the 62 mm clock watch is home to plenty of complications, including a grande and petite sonnerie, a perpetual calendar, and a minute repeater, as well as a splits-second chronograph. On the white-enamel dial, which shows off Arabic numerals, you can find a moonphase function and a leap-year cycle, too. The case, meanwhile, was crafted in a sculptural Louis XV-style for even more oomph, with A. Lange & Söhne’s movement nestled underneath that was based on a Piguet ebauche.

And, in a move unusual for the time, the coveted clock watch is free of any crests or coat of arms, emblems that would usually appear on a bespoke watch of this complexity, according to Sotheby’s. No. 62508 has remained in the same family since 1939, and this Sotheby’s auction marks the well-preserved model’s first public appearance in nearly 90 years—and it made quite a splash upon its return.

Though No. 62508 may have been the belle of the ball, Sotheby’s Geneva Important Watches Sale had plenty of other stunners up for grabs. A few watches from the house’s The Shapes of Cartier lineup, a treasure trove of ultra-rare, vintage Cartiers heading to auction throughout the year, fetched a pretty penny: A yellow-gold Driver netted $164,852, while a yellow-gold Tank Cintrée realized $197,823. Meanwhile, a Rolex Daytona “Paul Newman” hammered down for a record $1.5 million. Quite a day on the block, we’d say.
