The FC-718 calibrating movement is an extraordinary tool, not only because it has been designed, developed and manufactured in-house, but also because the functions of the Worldtimer and the date are all adjustable via the crown itself, without additional push buttons. To set the functions easily, you must choose between three settings; the first allows you to wind the watch by turning the crown upwards; the second allows the user to set the date and city by turning the crown upwards and downwards respectively; and the third allows the user to set the time by turning the crown downwards. This watch shows two separate discs, one with a 24-hour day-night indicator and a second with the 24 cities. As Manufacture movement, the FC-718 calibre is decorated with Perlages and Côtes de Genève, and has a 42-hour power reserve. The green movement is complete with a green alligator strap with white stitching.
