The Fontainemelon 701-2 watch movement is an open face calibre featuring a bimetallic screw balance with a recess in the stem for operating a set lever and a set-lever screw. Additionally, there is a post on the rocker designed for the pin-set feature. This movement offers various functions, including a manual-wind chronograph with 60 seconds and 30 minutes register, controlled by a pillar wheel. It can be both stem-wound and pin-set, with the option of a set lever and sub-second display. The Fontainemelon 701-2 movement was in use around the year 1900.
