• Masterpiece Régulateur Roue Carrée – limited edition - Squaring the circle
  
  Imagine the unimaginable. Stretch the limits to the point where perception changes perspective. Maurice Lacroix has chosen its flagship Masterpiece line to open a new dimension in watchmaking. The Masterpiece Régulateur Roue Carrée bears its name well: it reinvents the wheel and finds corners in the passage of time, but without changing its immutable regularity.
