About matthieu keller

For the passion for this small jewel which offers numerous mechanical complications, to highlight a perfect reading of time in a luxurious case.

Project O was founded by Matthieu Keller to realize innovative design concepts with new DNA, quality with artistic value.

Our watches are made with French industrial partners, that offer recognised know-how, except for the movement, with the bottom of the box being proudly engraved with the words “Made in France”, a country that can be proud of its long-standing contribution as the cradle of the development of timekeeping.

Our pieces are produced in France and assembled by hand in our Parisian workshop and even if we use industrial methods (polymer treatment * oblige), our company is artisanal and independent.
