aison Byrne announces with deep sadness the passing of its founder, John Byrne. A passionate creator and truly independent spirit, John belonged to that rare group of horological innovators who did not simply measure time, but sought to give it meaning, character, and soul. Guided by technical mastery, intuition, and a singular creative vision, he possessed a remarkable ability to bridge the time-honored traditions of fine watchmaking with a bold prediction of the future.

Nothing about John was ever static. He was constantly evolving, exploring, and discovering new possibilities.

It was in that spirit that he, alongside his wife, Claire Cohen, founded Maison Byrne, an independent and revolutionary studio that introduced a distinctive new language to contemporary horology. Those who knew John will remember a man of immense energy and imagination: radiant, inventive, generous, and deeply alive.

With John, a conversation could become a thought-provoking journey into unimagined possibilities, and a simple meeting could open the door to entirely new ideas and opportunities.

Before his passing, John worked closely with Claire to ensure the future of Maison Byrne with sharp clarity, resolute confidence, and unbridled optimism.

Today, Maison Byrne continues under the leadership of Claire, who will uphold the founding values that defined John’s vision: independence, creativity, boldness, freedom of expression, and mechanical excellence.

Supported by her teams and the LTM Manufacture, along with Maison Byrne’s partners and collaborators, Claire will ensure that John’s legacy endures while continuing to develop the enterprise they built together, along with the numerous projects on which they collaborated before his passing.
