The new Flyback edition goes further than the previous EVO editions: on top of the previous timing modes typically associated with motor racing, it adds the flyback function originally conceived for pilots, bringing the Sequential into the world of aviation. The new Flyback edition with sky blue dial plate comes in the more classic Legacy Machine styling, in a platinum case with screwed lugs and white lacquered dials – including a tilted hours and minutes dial – on a leather strap
The LM Sequential Flyback Platinum features the same layout as the LM Sequential EVO with 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 chronographs can be started, stopped, and reset completely independently of the other, using the start/stop and reset pushers on their respective sides of the case. With the new flyback function, the reset pushers also trigger the flyback if the corresponding chronograph is running. These pushers 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, called the Twinverter that controls both chronograph systems, operating as a binary switch that inverts the current start/stop status of each chronograph. This means that if both chronographs are stopped, pressing the Twinverter causes both of them to start simultaneously. If they are both running, the Twinverter makes them stop. And, if one is running and the other is stopped, the Twinverter stops the one that is running and starts the one that is stopped.
In terms of practical applications, these functions allow the chronograph to be useful in numerous situations, as the following examples illustrate:
Independent mode
Imagine the preparation of a meal, where different things need to be cooked for different periods of time, at different points in time. You would operate the two chronographs via their respective pushers — for instance, starting one when you put your pasta into boiling water and starting the other when the vegetables go in the oven. In fact, this application comes in handy in all areas of personal productivity. In this example, the new flyback function can come in handy to swiftly reset and restart the timing sequence with a single press on the reset button, combining the three steps – stop, reset to zero, and re-start – in one.
Simultaneous or split-second mode
This mode can be used in a race involving two competitors, starting simultaneously. The Twinverter allows the wearer to start both chronographs at exactly the same time, but the different end times 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 split-second chronographs on the market. In this mode, you can also use the new flyback function if you want to quickly restart timing.
Cumulative mode
In the work environment, you might want to know how much time you spend on two separate projects as you switch between them throughout the day. 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 spent on each task. Another example of this usage is the timing of a chess match.
Sequential mode (or lap-timer mode)
For those timing competitive sports, this mode can be used to measure individual lap times. 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. Thanks to its minutes’ totalisers, the LM Sequential can be used effectively in sporting events with average lap times of over a minute (which includes the vast majority of motor sports).
Flyback mode
The flyback originally developed in the 1930s for airplane pilots allows accurate timing of flight paths from waypoint to waypoint. The flyback allowed stop, reset and restart in a single press on the reset pusher. Combining the new flyback function with the other timing modes of the Sequential calibre offers even more functionality.
The design of the LM Sequential is completely unique. It encompasses two independent chronographs within a single movement, both of which are linked to a common escapement and oscillator. All this functionality within a single watch required the invention of a fundamentally new type of chronograph system, one which would not be susceptible to any sort of energy losses. This is exactly what the LM Sequential does, thanks to the use of its innovative internally-jewelled vertical clutches and their associated control system. The new flyback mechanisms also incorporate jewelled rollers. Thanks to these patented solutions, the Sequential calibre outperforms conventional chronographs in terms of energy efficiency and precision.
