Legacy Machine Sequential Flyback Platinum

Description

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, called the Twinverter, located at the 9 o’clock position. This “magic button” as Stephen likes to call it, is the secret that elevates the functionality of the LM Sequential timepieces 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 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.
