Here's a list and commentary about the wristwatches worn by nine of the most powerful CEOs in the tech industry.
Since it was invented over 200 years ago, the wristwatch has been an integral component of fashion.
In addition to their practical functionality of telling time, a watch serves as a collectible piece of art that communicates the personality and style of its wearer.
With the help of Crown & Caliber, an Atlanta-based pre-owned luxury-watch marketplace, we've put together a list and commentary about the wristwatches worn by nine of the most powerful CEOs in the tech industry.
The Wisconsin native was appointed the head of Yahoo in 2012 following a 13-year career at Google. Verizon officially closed its $4.48 billion purchase of Yahoo, the company announced Tuesday. Mayer will step down with a $23 million package.
Mayer's watch, an Omega Deville Symbol Quartz, retails for $4,900 but can be purchased pre-owned on Portero, a watch marketplace, for $985.
Apple's market cap surpassed $800 billion in May. As such, the iPhone-maker is one of the world's most valuable companies. And the man at the helm of it all is Tim Cook. He assumed the position as CEO in 2011.
Cook is rarely seen without his Apple Watch. You can purchase one on Apple's website. They retail starting at $269.
Amazon's stock has been climbing because of the proliferation of Amazon Web Services, Amazon's cloud-computing service. Its market cap stands at $465 billion. Amazon on Friday announced a $13.7 billion deal to buy Whole Foods.
Larry Ellison founded Oracle, the software technology company, in 1977. He served as the company's CEO until 2014. The billionaire, whose net worth stands at $55 billion, never finished college and once worked for the CIA.
Ellison has been photographed sporting a Paneral Luminor Marina. A version of this watch with a leather band retails new for $6,200, but can be purchased pre-owned on TheRealReal for $4,195.
Hurd joined Oracle in 2010, according to the software company's website. He took on the CEO position with co-CEO Safra Catz after Ellison stepped down in 2014.
He served as the CEO of Hewlett-Packard from 2005 to 2010. And he ended his nearly 25-year career at NCR Corp., the maker of ATMs and other software technology, as the company's CEO, a position he held for two years.
He served on the board of News Corp., the parent company of Fox News and owner of The Wall Street Journal.
Hurd wears a classic, the Rolex Dayjust. It retails new for $3,500 but can be purchased pre-owned on Bob's Watches for $3,350.
Satya Nadella was named the CEO of Microsoft in 2014 when he was 46 years old. Nadella has been with Microsoft for about 25 years.
Before being appointed CEO, he served as vice president of the computer maker's Cloud and Enterprise Group.
All right — this one is a guess on the part of Crown & Caliber. The team believes Nadella is sporting a Breitling Colt Automatic in the image on the previous slide. A used version of this puppy being sold on eBay will set you back $2,359.99. It retails new for $3,025.
Jeff Weiner has been the CEO of LinkedIn since 2009. The company was bought by Microsoft for $26.2 billion in 2016.
Weiner's watch, a Audemars Piguet Royal Oak, is the most expensive on this list. It retails for a whopping $17,800 but can be purchased pre-owned on Jomashop for $14,995.
Tony Aquila is the CEO of Solera Holdings, a Texas firm that produces risk-management and asset-protection software. It has a $3.6 billion market cap.
He founded the company in 2005. According to Aquila's executive profile, he was named "National Entrepreneur of the Year" by EY in 2013.
On the previous slide, Aquila is pictured wearing an Omega Seamaster Planet Ocean. A very similar model of this watch goes for $2,970.50 pre-owned on Tradesy.
Another version of this watch with a blue face is being sold on Crown & Caliber's site for $4,110. It retails new for $7,200.
Aquila has also been photographed sporting a Fitbit. The most basic model goes for $29.99.
Steve Kaufer cofounded TripAdvisor, a travel-planning site, in 2000. The idea for the firm was triggered by Kaufer's own experience planning a trip to Mexico, according to an article in The New York Times.
Before TripAdvisor, Kaufer was the president of CDS Inc., a software company.
Kaufer sports a Omega Deville Prestige. Watch lovers can buy one on Walmart's website for $2,323.38.
