LM Sequential EVO

Fully integrated dual chronograph system developed for MB&F by Stephen McDonnell, featuring Twinverter switch allowing multiple timing modes Manual winding with double mainspring Flying balance wheel with regulating screws at 12 o’clock Superlative hand finishing Power reserve: 72 hours 585 components / 59 jewels The Twinverter switch allows the chronograph to be used in various modes; •“Independent mode”: measure the duration of multiple events with separate starting points and end points, even when the events overlap in timing; Independent mode can be used for instance in the preparation of a meal, where different things need to be cooked for different periods of time, at different points in time. • “Simultaneous mode”: measure the individual durations of two events that start simultaneously, but have different end points; The Twinverter allows to start both chronographs at exactly the same time, but the different end points can be easily recorded by pressing each chronograph’s individual start/stop pusher. To note, the durations of the events can exceed 60 seconds, which is the limit for the vast majority of splitsecond chronographs on the market. • “Cumulative mode”: measure the individual cumulative durations of two discontinuous events; By starting one chronograph when you begin working on one task, and then using the Twinverter when you shift focus to the second task (switching again when you go back to the first), you can easily track the amount of time you cumulatively spend on each task. • “Sequential mode (or lap mode)”: measure the individual sub-durations of a single continuous multiphase event, with provision for sub-durations that last over a minute. Starting one chronograph at the beginning of an event and using the Twinverter upon the completion of a lap instantly launches the second chronograph in order to time the next lap, while the first chronograph is stopped, allowing ample time for the timing result to be noted down. The stopped chronograph can then be reset to zero, ready to be relaunched with the Twinverter for the following lap
