Retrograde seconds with two parallel rotors

The originality of this movement, developed by Paul Gerber for Perrelet, lies in the fact that the barrel is charged by two synchronised parallel 18-carat gold rotors, visible through the transparent case-back. The perfect equilibrium of the display is accentuated by the hand-crafted guilloch? motif. The tonneau shape lends a refined elegance to this creation issued in four limited editions of 25.
