A new feat from Cédric Johner, the Geneva-based watchmaker, who has accommodated a chronograph movement with a column wheel in his famous Abyss case, with functions that are activated by means of a single push-button crown. A true “master’s touch” is evident in the perfect craftsmanship: a case-middle fashioned with a file, hand-engraving and hand-guilloché, and the meticulous finish of the movement.
