“I spent years dragging half-functioning prototypes through expeditions, fully committed as my art regressed — forming a design for the M which preserves exactly what makes it so special. It’s manual. It’s mechanical. It forces you to slow down and find rhythm in the challenge. It’s honest. Thousands of hours, endless revisions, a standard only this team can sustain. Live in the detail.”
