Chapter One
With Chapter One, Maîtres du Temps has achieved an as yet unmatched technical feat: that of uniting a tourbillon, a mono-pusher chronograph, a retrograde date, a retrograde GMT and two separate rollers indicating the day and the phases of the moon respectively. It took the combined talent of Christophe Claret and Peter Speake-Marin, together with the momentum provided by Steven Holtzman, for this youthful brand to revolutionise the world of grand complications.
