A $55 million necklace gets the attention. The family business behind it runs on something quieter: knowing which stones to cut, which customers to follow, and which stories deserve a setting.

Bob's Watches is the world's largest online marketplace dedicated to pre-owned Rolex and luxury watches. Founded in 1999 and reshaped by CEO Paul Altieri after 2010, the company pioneered the transparent 'Rolex Exchange' - publishing live buy and sell prices for every model, like a stock exchange for watches. Based in Newport Beach, California, it authenticates and holds its own inventory of certified used Rolex, Patek Philippe, Omega, Tudor, Cartier, Audemars Piguet and more, letting collectors and first-time buyers transact at fair market value.
