Mille's wristwatches are wonders of advanced engineering that were developed using real world R&D: they are put through the ringer by
athletes during training and competition until they break,
enabling Richard Mille's team to find the weak spots in the tiny movements and re-engineer the watch until they're durable enough to sustain extraordinary forces like the swing of a golfer's club, the violence of a Formula 1 driver's
track battle, or the snap of a tennis player's racket.
