Sylvester Stallone auctioning off ‘holy grail’ of watches as part of $7.5M collection

Sly might be late on set.

Sylvester Stallone is auctioning off part of his staggering $7.5 million watch collection at Sotheby’s starting on June 5.

The highlight of the lot is the “Rocky” star’s Patek Philippe Grandmaster Chime — considered the “holy grail” of the watch community — which could fetch between $2.5 and $5 million.

It is “one of the most complicated wristwatches in the world,” Sotheby’s Head of Watches for the Americas, Geoff Hess, said in a statement, according to NewsNation’s Paula Froelich.

The rare timepiece is “an impressive white gold double face wristwatch featuring 20 complications,” according to its listing on the auctioneer’s site, and even comes with a “personally signed handwritten note from Sly.”

“I enjoy the collecting process like so many others in this passionate community, who don’t just see watches as an accessory, but admire them for their history, craftsmanship, artistry – but most importantly – how they make them feel,” Stallone said in a statement.

“Looking at these watches, I feel truly lucky to have owned them; they serve as a reminder that hard work pays off … While parting ways with this collection is bittersweet, I cherish that I’ve owned them with pride, and hope they will be appreciated and admired in their next homes.”

Other Stallone watches on the auction block, which all either have his signature engraved on them or have his name somewhere on them, include a Patek Philippe Nautilus, believed to command up to $100,000, and an Audemars Piguet Royal Oak Tourbillon, slated to take in up to $200,000.

There’s also a Panerai Luminor Submersible 1950, which the actor wore in the 2012 movie “The Expendables 2,” that could fetch $60,000.

“While many recognize Stallone as the legendary actor behind characters like Rocky Balboa and John Rambo, watch enthusiasts know the legendary actor to be a noteworthy, influential and truly passionate collector,” Hess continued in his statement.

Stallone, who is filming Season 2 of “Tulsa King,” recently relocated with his wife, Jennifer Flavin, to Palm Beach, Fla., leaving their longtime Los Angeles home, so maybe they didn’t want to pack all the watches.
