Watch Fact of the Day: The $24 Million Watch With a Secret New York Sky! So, back in 1933, American banker Henry Graves Jr. commissioned the Patek Philippe Graves Supercomplication, a mind-blowing watch that took eight years to make. This double-sided yellow-gold pocket watch packed 24 complications, including a perpetual calendar and a celestial chart of the night sky above his Manhattan home. It was the world's most complicated watch for a whopping 56 years! It ended up selling for a jaw-dropping $24 million at a 2014 auction. This watch isnât just about timekeeping; it showcases the brilliant craftsmanship of a bygone era, long before the tech we have today.
