Nicholas Manousos is an internationally recognized horologist based in New York City. He is a Board Member at The Watch Library Foundation and a Member of the Academy at the Grand Prix d’Horlogerie de Genève. Manousos has been featured in The New York Times, Bloomberg, Esquire, New York Magazine, GQ, and Scientific American, appeared in the film Keeper of Time, and consulted on HBO's The Gilded Age.

Over thirteen years at the Horological Society of New York (2013-2026), Manousos transformed a struggling organization into a thriving institution with $3 million in annual revenue, a 25,000-volume horological library, acclaimed programming, and a celebrated annual gala at The Plaza Hotel. During his tenure as Executive Director, HSNY awarded more than $1 million in scholarships to over 160 watchmaking students around the world.

Today, Manousos is focused on a new project in New York City, drawing on more than a decade of institution-building to broaden public engagement with horology.
