Square Micro‑Rotor


55,000 CHF

The Square Micro-Rotor, with its stylish design, comes back with an autumn-toned look after the gold-toned sunburst dial. For this version, LAURENT FERRIER treats its Square Micro-Rotor with autumn or red gold colours, with copper glints thanks to the vertical satin-brushed finish. The movement is still the self-winding FBN 229.01 calibre with a natural escapement.

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.
