These are the watches worn by Wall Street's most powerful men

Oil magnate T. Boone Pickens also wears a yellow gold Rolex Day-Date that he purchased in 1964.

Goldman Sachs CEO Lloyd Blankfein rocks a Swatch with what appears to be a clear plastic band. Swatch's tend to range between $50 to $245. It's also not exactly the sort of timepiece you'd expect a chief executive of a Wall Street investment bank to wear. Then again, Goldman is "the most hipster" bank on Wall Street.

Billionaire private equity chief Stephen Schwarzman also wears a Swatch. He also uses a flip phone.

Investing legend Jack Bogle, the founder of the Vanguard Group, wears a $14 wristwatch he received from a shareholder.

"I received in the mail a wristwatch from a devoted shareholder in California. On the dial were printed our Vanguard logo, my name, and a phrase that was an indication I was still looking out for our shareholders: "Still on Watch." It was also an outrageous pun: "Still on Watch." Confident that it would be my rabbit’s foot, I put the watch on my wrist, where, having proved itself, it remains to this day. (Yes, I knew about the $50 limit on gifts. So I checked the catalog for the price. It was $14. Talk about value!)," he wrote.

Ackman, the billionaire activist investor, wears a stunning Patek Philippe Ref. 5216P.

Billionaire Carl Icahn, the famed activist investor, appears to wear The A Lange & Sohne Grosse Langematik Gangreserve in this TIME magazine cover from December 2013.

Hedge fund legend George Soros was seen wearing this Patek Aquanaut back in 2010.

We learned about Jeff Gundlach's watch collection when he had a bunch of his artwork and personal property stolen in 2012. According to the Santa Monica Police Department report, the watches that were stolen included a Glashutte, Breitling, A. Lange & Sohne, TAG Heuer and a Patek Philippe. We couldn't nail down prices for these specific models, but every one can run in the tens of thousands of dollars or more.

Talk about some serious wrist candy though! Fortunately, the DoubleLine Capital CEO brilliantly helped the FBI recover his stolen property.

Private equity chief Lynn Tilton, the founder of Patriarch Partners, wears a massive bejeweled timepiece by Jacob the Jeweler.

It definitely fits her "dust to diamonds" persona. In August 2014, she received a personalized Rolex timepiece along with a pretty big tennis award.

Former hedge fund manager Phil Falcone, who recently spoke in public for the first time in years, wears a black sports watch (it looks like Casio G-Shock) and some friendship bracelets and beads. We're assuming his twin girls made those for him.

Billionaire retired hedge fund manager, Tom Steyer, wears a sporty Ironman watch.

The billionaire "Tiger Cub" hedge fund manager also wears a sports watch. We can't tell what the make or model is. Halvorsen runs marathons and competes in triathlons.

Morgan Stanley CEO James Gorman wears what appears to be a stainless steel Rolex Daytona, according to Ben Clymer, the founder of watch site Hodinkee.

BONUS: Jamie Dimon doesn't wear a watch! Ever. Apparently, he doesn't care for jewelry.
