The watch Jay-Z is wearing in that photo isn't just a watch.
You can't just walk into a store and buy this, even if you have $6.5 million cash.
Patek Philippe requires an application process. They look at your history as a collector to ensure the watch goes to someone who deserves it (and won't immediately flip it for profit).
For a watch like this, you aren't paying for the time; you’re paying for a combination of extreme engineering complications, rarity and wearable art.
In watchmaking, a complication is any function beyond telling the hours and minutes. This specific watch has 20 complications and over 1,366 individual parts.
It knows the difference between months with 30 and 31 days and even accounts for leap years without needing a manual reset until the year 2100.
The watch is double-faced. There are dials on both the front and the back. The lugs are designed so you can flip the watch over to see the other face while it's still on your wrist.
While most modern watches are made by machines, every single one of those 1,366 parts in the Grandmaster Chime was hand-finished.
A luxury car loses value the moment you drive it away, a Patek Philippe often gains value. For example, a unique stainless steel version of this exact model once sold at auction for $31 million.
