Mark Zuckerberg is a certified watch guy. His collection ranges from a $120 Casio to multimillion-dollar timepieces.

While attending Ambani’s pre-wedding party in March 2024, Zuckerberg and his wife, Priscilla Chan, were seen admiring a Richard Mille watch worn by the Reliance Industries heir.

“You know, I never really wanted to get a watch, but after seeing that, I was like, watches are cool,” Zuckerberg is heard saying in a video of the interaction.

While he clarified to Chan that he wasn’t interested in buying the same watch, he said he’d consider similar options.

On September 1, 2024, Zuckerberg shared an Instagram photo of himself embracing his wife. In the image, his wrist was adorned with a large watch featuring a gold face and a brown strap.

Zuckerberg indulged watch fanatics who asked for details, sharing that the watch was a “5236P,” or a Grand Complications In-Line Perpetual Calendar watch from Patek Philippe.

The timepiece is crafted with a platinum case and an alligator-leather band. In terms of functionality, it displays the current day, date, and month. It also indicates leap years, moon phases, and whether it’s day or nighttime.

It originally retailed for $148,331, but has since been discontinued.

Zuckerberg appeared at an “Acquired” podcast event on September 10, 2024. While onstage, he was photographed wearing another flashy watch: a DB25 Starry Varius from the Swiss watch brand De Bethune.

He seemed to be wearing the rose-gold model, which can cost over $80,000 from independent watch sellers. As watch specialist Bryan Li previously told Business Insider, only 20 of the watches were made annually.

Other variants — like one made from titanium and another encrusted with 273 diamonds — can cost between $69,000 and $127,000.

There’s also the Aérolite version of the watch, which features a dial made from a meteorite and usually costs $260,000.

This De Bethune piece — and Zuckerberg’s Patek Philippe watch — showed a significant shift in the Facebook founder’s style, taking his outfits from basic to luxe almost overnight.

He was photographed onstage at the 2024 Meta Connect conference wearing a chunky silver watch. It appears to have been a variant of a watch from the Swiss brand F.P.Journe’s Souveraine collection.

The specific one Zuckerberg wore featured a thick band and large black buttons on its side. Sotheby’s previously listed what appears to be the same watch for auction and said it was entirely made of aluminum.

The auction company also said the watch style was produced between 2011 and 2014. The piece was estimated at $31,000 to $56,000, though it’s unclear what it actually sold for.

The same watch in a darker gray colorway is now available to purchase online for $299,000.

On January 8, 2025, Zuckerberg posted a video to announce the end of Meta’s fact-checking partnerships in the US. In the clip, he’s seen wearing a Greubel Forsey watch that retails for over $900,000.

According to the brand’s website, the watch is assembled entirely by hand, and only two or three are crafted each year. It’s made with white gold and contains 281 pieces.

Michel Nydegger, the CEO of Greubel Forsey, told Bloomberg at the time that Zuckerberg showed “true appreciation for the most traditional approach to fine watchmaking” by wearing the piece.

Zuckerberg posted a handful of photos and videos from the mixed martial arts event, which showed a thick gold watch on his wrist.

Business Insider spoke with four watch experts at the time, who all said the timepiece was likely a yellow-gold Rolex Daytona Le Mans.

Though Rolex has never confirmed how many exist, collectors and sellers say the watch style is rare.

That’s partially why it had a resale value of up to $300,000, as Ng Yong Shen, a vice president at the Dubai-based secondhand retailer Re-Loved Luxury, told Business Insider.

In April 2025, Zuckerberg appeared on The Colin and Samir Show wearing a white timepiece with a vibrant blue face.

Watch fanatics quickly pointed it out as the GA2100WS-7A from Casio’s G-Shock line. Made from resin and mineral glass, the watch retails for $120.

So far, it’s the least expensive watch Zuckerberg has worn in public.

When clips of the podcast appearance were released, watch fanatics quickly noticed the F.P.Journe Chronomètre Bleu Byblos watch on Zuckerberg’s wrist.

The design was made only 99 times in 2014, and each watch costs a pretty penny. One sold at a Sotheby’s auction for $254,000 in April 2025.

Zuckerberg specifically wore the George Daniels Anniversary timepiece, made in collaboration with British watchmaker Roger Smith in 2010.

It was designed to honor George Daniels and the 35th anniversary of his engineering and horological feat: the invention of the coaxial escapement.

Sotheby’s listed the watch for auction in 2025, with an estimated sale price between $400,000 and $800,000.

A representative for F.P.Journe confirmed with Business Insider that Zuckerberg wore a Tourbillon Souverain Cœur de Rubis, reference TN, Calibre 1403.

The watch features a distinct ruby dial and a thick yellow-gold bracelet.

Phillips, an auction house that sold one of the rare watches for 1,633,000 Swiss francs, or about $2 million, in 2025, says only 20 were made between 2019 and 2020.
