Kyle Marlow

Kyle is the founder of Prosperity Time and the senior authenticator on every watch the firm transacts. He has personally sourced, inspected and resold more than 5,000 luxury watches across Rolex, Patek Philippe, Audemars Piguet, Richard Mille, Cartier and Vacheron Constantin since opening the business in 2017.

He works with private collectors, family offices and watch boutiques worldwide, and is regularly consulted on market pricing, complication-level authentication, and reference history. His writing on this site is grounded in the watches he sees, buys and sells every week — not desk research.

Kyle is based between Miami and New York and travels to Geneva, Dubai and Singapore for inventory and client meetings several times a year.
