Unlike in typical gears, the interaction between the part being driven and the part doing the driving is not continuous and the resultant motion is intermittent. Vacheron Constantin chose this symbol because it represents the shape of the component that fixed to the barrel of its movement, which reduces the amount of wheels necessary for winding. The eight-pointed cross is also used to identify the final approach fix in a nonprecision instrument approach (one that lacks precision vertical guidance), in contrast to the use of a lightning bolt-type icon, which identifies the final approach fix in a precision approach. The Maltese cross flower (Lychnis chalcedonica) is so named because its petals are similarly shaped, though its points are more rounded into "heart"-like shapes. [citation needed][year needed] A discontinuity appears in the acceleration when the drive pin enters and leaves the slot, occurring at the instant the rigid bearing surfaces make contact or separate. The rotating drive wheel is usually equipped with a pin that reaches into a slot located in the other wheel (driven wheel) that advances it by one step at a time. The Geneva drive or Maltese cross is a gear mechanism that translates a continuous rotation movement into intermittent rotary motion. The first evidence of the Maltese Cross comes from copper coins for the Grand Master Jean Parisot de la Vallette, who was the Grand Master of Malta from 1557-1568.

The angle by which the drive wheel has to rotate to effect one step rotation of the driven wheel is always smaller than 180° in an external Geneva drive and always greater than 180° in an internal one, where the switch time is therefore greater than the time the driven wheel stands still. The use of the green eight-pointed cross by the Order was retained right through to the 19th century and after the secular organization of the Order after 1910.
