The exterior of the Sport Auto is a refined interplay of firm and rounded curves enlivened by a few counter-curves outlining a bodywork with a perfectly balanced design. The domed sapphire dominates the watch while giving it an irresistible curve to the touch. The latter offers a bird’s-eye view of a dial bringing together all the LAURENT FERRIER aesthetic codes. Its different shades of blue, combined with its opaline finish, gives it a soft and powdery line.

The Maison’s second automatic calendar movement, the LF 270.01 calibre, is the result of an exclusive LAURENT FERRIER development. As a subtle blend of a tribute to the Micro-Rotor with natural escapement and a more assertive and sporty style, this movement is entirely designed, decorated, assembled and adjusted in the LAURENT FERRIER workshops. More suited to sports watches, this is a Swiss lever escapement using an automatic winding system with an off-centre micro-rotor. For non-negligible benefits in terms of resistance to shocks and vibrations, this movement is fitted with a unidirectional ball bearing replacing the traditional ratchet system.
