• the amplitude of a balance in a standard mechanism depends, among other things, on the energy available in the metering wheel distributed by the barrel. So we understand that if the two rockers wanted to work simultaneously, the barrel would not distribute enough energy, and if the barrel dispensed twice as much energy, one of the two rockers would receive too much energy when the other is stopped. It is therefore essential to manage the force distribution of a single barrel to one or the other of the two exhausts.

Instead of allowing the mechanism to automatically switch the passage from one exhaust to another, as described above in the indication of an AM / PM of FIGS. 1 to 5, it is conceivable to adapt a control push-button so that , manually and on demand, we can determine which exhaust receives the energy of the barrel.
• the spring 33 has two functions:
• the mechanism which has just been described with reference to FIGS. 1 to 5, allows for example every twelve hours to automatically activate one whirlpool or the other. We could also go from one cage to another, for example every hour, by operating a tourbillon cage every even hour and the other every odd hour.
• the mechanism makes it possible to transmit the energy of the barrel
• the mechanism makes it possible to stop and actuate all other types of escapements, for example a standard Swiss anchor escapement and a standard balance wheel, in an automatic or programmed manner or at the request of the user. .
• the mechanism also makes it possible to activate a type of escapement for a defined period of time, for example a detent escapement and, for another defined period of time, an exhaust of the other type (standard Swiss lever escapement or other ), etc.
• the mechanism that has just been described has the following advantage: We can simply say that the time counted by a watch containing several exhausts is more accurate than a watch containing only one escapement since at the end of a period of twenty four hours, the counted time is the arithmetic mean of all the time counted by the different escapements.
• the advantage is also to cause wear of the components of the assortment at least 50% lower than normal.
