TAG Heuer Just Reinvented the Chronograph Mechanism. The Monaco Evergraph Is Worth $25,000.
TAG Heuer's Monaco Evergraph replaces the century-old lever-and-spring chronograph mechanism with compliant bistable components that don't wear the same way. At $25,000 it's the most technically ambitious watch TAG Heuer has released in a generation — and a genuine argument for why watchmaking progress matters at this price.
