When it comes to building a luxury watch portfolio, it helps to have a superstar salary. But most of us start with one primo piece that may be our forever watch or the cornerstone of a collection. Celebrities operate much the same way, and here we've rounded up some boldface favorites that you can acquire on the pre-owned market for quite reasonable prices:

George Clooney: Omega Speedmaster Professional

Clooney is an Omega spokesman but we're pretty sure he'd be sporting a Speedmaster anyway as it's a perfect fit for his timeless brand of cool.

David Beckham: Tudor Heritage Black Bay

Becks has a big watch collection but the one that seems to suit him best is the Tudor Heritage Black Bay. Like the man himself, it's handsome and a bit edgy.

Jay-Z: Audemars Piguet Royal Oak

The classic AP brings just the right amount of bling for Hova but it's also a watch connoisseur's choice and shows he cares about haute horology.

Bradley Cooper: IWC Big Pilot

Cooper's style is always on point and his choice of timepiece is no exception. The Big Pilot is also one of our all-time favorites.

Mark Wahlberg: Rolex Yacht-Master II

A rather nautical choice for the tough-guy actor but he pulls it off admirably. Perhaps he'd rather be sailing?

Roger Federer: Rolex GMT-Master II

The GOAT is a Rolex ambassador so of course, he sports nothing else, but we can't imagine the Swiss ace wearing a lesser watch, can you?

Idris Elba: Rolex Day-Date

The future 007 prefers the solid gold version of Rolex's classic dress watch and it's often the most colorful note in his carefully chosen monochromatic ensembles.

Daniel Craig: Rolex Milgauss

Rounding out the Rolex crowd is James Bond himself, who wears an Omega onscreen but prefers a Roller in private life, as did the original 007.

Patrick Dempsey: TAG Heuer Monaco

Dempsey races Porsches when he's not in front of the lens and the iconic Monaco was of course made famous by another speed-loving actor, Steve McQueen.

Brad Pitt: Panerai Luminor GMT

The Luminor GMT is one of Panerai's lesser-known pieces, and just as Pitt remains something of an enigma his decision to wear one fosters an air of mystery.
