The watch is double-sided, with its top face featuring four subdials and its inner face showing the position of the stars.Apart from telling its wearer the time, the watch also shows the sun's position, height, trajectory, and angle relative to the Earth.

But a watch with this many complications is "extremely delicate," Altieri said. Any servicing required would likely take months, and can probably be done only by Vacheron's top-level master watchmakers in Geneva, he added. "Collectors and horological folks will worship it, but it's definitely not meant for mass appeal. It's meant as a show-stopper. A jaw-dropper," Altieri said.Recommended video
