There’s nothing a watch collector hankers after more than a holy grail timepiece. Exquisiteness aside, these watches are often the pinnacle of high-end horology, but it is ultimately their rarity that makes them so desirable.

Still, not every limited edition watch makes the cut. When Rolex first launched its Pepsi-bezelled GMT-Master II out of practical reasons, no one quite expected that it would become one of the most highly demanded timepieces in history. This fanaticism didn’t wane when it relaunched the steel version last year, a sure sign that the watch had indeed reached holy grail status over the decades. The waiting list for it? Possibly near eternity, unless you’re ready to empty your bank account on a resale site. 

Below, a list of the holy grail watches that have massive waiting lists. Time to make some friends in the industry then.
