Minimal thickness becomes the defining achievement of the RM 67-02 Extra Flat. The watch was developed to deliver the lightest possible wearing experience while preserving the unmistakable mechanical complexity associated with Richard Mille design. Its low profile case curves naturally along the wrist, creating a highly ergonomic fit that feels dramatically different from the larger and more aggressive proportions typically associated with the brand.

Beneath the sapphire crystal, the skeletonized automatic movement reveals a carefully optimized mechanical layout engineered around compactness and reduced mass. Richard Mille integrated lightweight composite materials throughout the case structure to further improve flexibility and sports functionality. The RM 67-02 Extra Flat stands out as one of the most technically wearable references ever produced within modern haute horology sports watchmaking.
