MB&F LM Sequential EVO

Beyond the chronograph

Maximilian Büsser never said that MB&F would never make a chronograph. What he did say is that MB&F would never make a chronograph like all the other chronographs out there. Those who spoke the language of MB&F always knew what this meant. All good things come with time; better things come with more time, and after 17 years of creating horological art, MB&F brings us something better.

Introducing Legacy Machine Sequential EVO, featuring the debut appearance of MB&F’s 20th movement, in the first chronograph wristwatch of MB&F. Indeed, it is also the first chronograph wristwatch of its kind.

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. 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.

  • The LM Sequential EVO is our 20th calibre – no small feat coming from a small, independent company founded just 17 years ago.
  • Conceived by our Friend from Northern Ireland, the one-and-only Stephen McDonnell, who previously reinvented for MB&F the perpetual calendar complication with the award-winning LM Perpetual.
  • For our first-ever chronograph, Stephen has done it again, reinventing the classic complication by incorporating into a single movement two column-wheel chronographs, along with a groundbreaking “Twinverter” binary switch.
  • The result is a chronograph allowing multiple timing modes including split-second, independent and lap timer modes – a combination never seen before in any existing chronograph.
  • The ergonomic EVO case in zirconium features 80 meters of water resistance, screw-down crown, integrated rubber strap and the ‘FlexRing’ shock-absorbing system.

Legacy Machine Sequential EVO launches in two zirconium editions: with atomic orange dial plate (orange CVD) and with coal black dial plate (black PVD).
