When it comes to professionalism, charisma, fashion sense, and personal appearance, no man has a better reputation than popular television and radio host Ryan Seacrest.  That dude is everywhere and he does a great job in every hosting gig.  If you wonder what kind of wristwatch Ryan Seacrest wears, the mystery has been solved.  Ryan Seacrest often wears a vintage Rolex.
According to Bob's Watches, Ryan often wears a vintage 
Rolex Daytona Reference 6239.  The popular watch blog spotted him wearing the watch to the Golden Globes.  Here is the same watch below worn by Seacrest when he hosted a USO function.

In searching through images of Ryan Seacrest on the web, I've seen this same watch repeatedly in promotional shots for his short-lived 2015 show "Knock, Knock Live" and in photos of USO functions hosted by Seacrest.  This particular watch dates back to the late 1960s.

Emulating the Style of Ryan Seacrest's Watch 
If you had money and wanted to recreate the Ryan Seacrest look, it would be a simple matter of finding a similar 
Rolex watch.  On mere mortal salaries, it's a bit more of a challenge to emulate the look of the Ryan Seacrest Rolex.  However, finding all black subdials and a white dial can be a bit of a challenge.
