Conceived by one of the very earliest MB&F collaborators and Friends, Stephen McDonnell, LM Sequential
EVO explodes the current limits of what we thought chronographs could do. Just like the 2015 Legacy Machine Perpetual, the last major Stephen McDonnell movement for MB&F, LM Sequential EVO involved a back-to-the-drawingboard approach towards our most basic assumptions on chronograph construction.

The dial plate of LM Sequential EVO, available in atomic orange or coal black, features two chronograph displays. One has its seconds display at 9 o’clock and minutes display at 11 o’clock. The other has its seconds display at 3 o’clock and minutes display at 1 o’clock. Each of these chronograph displays can be started, stopped, and reset completely independently of each other, using the start/ stop and reset pushers on their respective sides of the case.These make up the four chronograph pushers you would
usually associate with having two chronograph mechanisms in one watch. However, there is a fifth pusher, located at the 9 o’clock position: the “Twinverter”. This pusher is the secret that elevates the functionality of the LM Sequential EVO beyond any existing chronograph wristwatch. It controls both chronograph systems, operating as a binary switch that inverts the current start/stop status of each chronograph. This means that if both chronograph displays happen to be stopped (at zero position or otherwise), pressing the Twinverter will cause both of them to start simultaneously. If they are both running, the Twinverter makes them stop. If one is running and the other is stopped, the Twinverter stops the one that is running and starts the one that is stopped.
