Hand-Wound Chronograph Explained: Vacheron Harmony | MR PORTER

The hand-wound chronograph is, for many collectors, the purest expression of mechanical watchmaking — a stopwatch on the wrist, ticking only because you wound it this morning. In this About Time episode we examine the VACHERON CONSTANTIN HARMONY, a modern chronograph with one of the most spectacular display casebacks in watchmaking. Through the sapphire panel, you can watch the column wheel and horizontal clutch dance in real time. It's less a watch, more a physics lesson — and a reminder that the oldest complications are still the most captivating.
