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.

This project’s designer, Matthieu Keller, chose to found this company under the name of Project O - Concepts, "O" for the chemical symbol for Oxygen, which perfectly represents our first O1 concept watch.

We want to offer a quality product at a reasonable price while giving it a real 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.
