Square Micro‑Rotor
Gold toned [Archive]


55,000 CHF

Laurent Ferrier has devoted particular attention to the aesthetic harmony of the Square Micro‑Rotor. This involved carefully aligning the ratio between the volumes of the case and that of the movement. This cushion‑shaped case is intended to assert a bolder presence on the wrist than the Classic one. The finishes reflect the high standards LAURENT FERRIER imposes on all its creations. All are performed in keeping with the finest watchmaking traditions.

This automatic calibre features a natural escapement. It offers two exclusive characteristics: a micro-rotor pawl-fitted automatic winding system, assisted by an exclusive silicon double-direct impulse escapement fitted directly on the balance, inspired by the father of modern horology, Abraham-Louis Breguet. This modern construction, associated with the use of cutting-edge materials,
maximises the restitution of energy.

The exceptional finishes of the movement are crafted in the finest watchmaking traditions. In addition to a Côtes de Genève pattern on the bridges and the circular graining on the mainplate, the flanks are hand-drawn, the wheel spokes are bevelled, the screw heads are polished, and the interior angles of the balance-cock are hand crafted with a burin. The micro-rotor bridge is hand polished.
