The Ultra-Thin demonstrates Calibre's engineering mastery at its most restrained. The entire watch measures 4.8 mm from caseback to sapphire crystal — thinner than a stack of three coins — achieved through a proprietary peripheral rotor that winds the mainspring from the movement's outermost edge rather than from its centre. The 36 mm rose gold case disappears beneath a shirt cuff, its presence felt only by the faint mechanical heartbeat at the wrist.
