Audemars Piguet 4401
High confidenceAP's first fully integrated in-house chronograph in the Royal Oak, replacing the modular construction of the earlier generation. Flyback function is the field test: pressing the reset while running should restart the chronograph from zero rather than requiring a stop first. An earlier Royal Oak Chronograph will not do this.
