Every year, the Maison returns to the same truth, told anew: time is only ever a passing hour. Everything made here, every bridge, every axis, every dial, exists for that philosophy alone: to watch (the) Time move, and to make it visible. For Geneva Watch Days 2026, Emmanuel Bouchet presents two new additions to the Source collection: Source Aleph Day and Source Aleph Night. In these timepieces, the Master Watchmaker's singular deconstruction of time is illustrated in a playful, nostalgic, and figurative register, with hand-painted elements set against a background of stone that evokes the daytime sky in chalcedony, or the night sky in aventurine.
