![]() ![]() It can be observed that the chronograph levers are unusually wide and flat, a profile that allows them to fit within the narrow vertical space under the crystal that is nonetheless laterally expansive due to the diameter of the movement. In fact, the slimness of the chronograph works are more noteworthy than the construction of the chronographs themselves. ![]() If anything, it is a clever construction that optimally utilises the narrow space between the base movement and domed crystal. It appears that a flyback can be incorporated with some modifications, but perhaps that extra is being saved for subsequent editions.īesides the clever-but-simple Twinverter, the movement is at heart two identical but mirrored chronograph mechanisms mounted on the dial side of a base movement. The Twinverter is arguably the most novel aspect of the movement, though it is easily understood, having been built according to familiar mechanical principles.Īt the same time, the movement has a notable omission: a flyback function. In between the two chronograph sits the Twinverter, a secondary mechanism that toggles the on-off state of each chronograph’s column wheel. The double chronograph is actually twin stopwatch mechanisms that are entirely independent and conventional – an approach that calls to mind the twin time zone watches of the 1970s that relied on two tiny and separate movements. The degree of optimisation and thought in its details is impressive, a fact brought home when Mr McDonnell himself explained the movement. The movement is certainly complicated in the sense that it’s made up of a lot of parts – almost 600 to be exact – but the approach is straightforward: the movement is at its core composed of a pair of identical, independent chronograph mechanisms, albeit executed in a thoughtfully optimised and compact manner. Despite its size, the watch wears well due to the shape and length of the lugs, while looking like a grand complication on the wrist.Īnd once I understood that it was a double chronograph, I was even more impressed it looks even more complicated than the top contenders in the category, namely the Lange Triple Split and Audemars Piguet Royal Oak Concept Laptimer.īut after understanding the movement, it is apparent that the watch looks more complicated than it actually is. ![]() It is a big, imposing watch with sleek lines and a wide face that is filled to the edges with intricate mechanics and quadruple sub-dials packed tightly together. I was impressed by the LM Sequential EVO when I first saw the watch. But the setup is a simple one, essentially two discrete chronograph mechanisms that operate independently but linked by the inverter mechanism. Developed by Stephen McDonnell, a constructor who’s been a longtime collaborator with MB&F, the movement is a double chronograph capable of recording twin times simultaneously along with a “Twinverter” mechanism that can either operate both chronographs or invert them – a complicated endeavour. The LM Sequential EVO is most interesting for its movement, which is paradoxically complicated yet simple. Christened the Legacy Machine Sequential EVO, the new chronograph continues with the same aesthetic of an open dial that reveals the mechanics along with a streamlined case. MB&F has just rolled out its very first chronograph, which becomes the second model in its EVO line of sports watches that began with the LM Perpetual EVO, now the brand’s bestselling watch.
