Certainly an intriguing watch. Love the case shape. The @ferdinandberthoud Chronomètre FB 1. Love the exposed dial at 6 o'clock displaying the seconds wheel and the Tourbillon driving wheel. At 9, the exposed power reserve is neat too. Shot for @williamandson at #salonqp2016 #ferdinandberthoud #chronometre (at Saatchi Gallery)
