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-drawing-board 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. 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.

As MB&F enters the last stretch of its second decade, it’s appropriate that someone who helped the brand come to life is instrumental in bringing it to a new level of horological legitimacy. The 20th calibre of MB&F is more than a recorder of time. It is a recorder of history — between Maximilian Büsser, the brand he created, and the watchmaker who was there from the beginning.
