The standout feature of this watch is its patented Butterfly Rotor, which allows the wearer to directly interact with the winding mechanism. It effectively gives the watch a “Sport Mode.”
-
City/Normal Mode: The rotor segments are positioned together in a semicircle. Gravity creates the torque needed to wind the watch as your arm moves.
-
Sport Mode: By pressing the pusher at 7 o’clock, the rotor segments split into a 180-degree “butterfly” shape. This balances the center of gravity, suspending the winding process.
-
The Purpose: This prevents the movement from “over-winding” or sustaining internal wear and tear during extreme physical activity, like professional tennis.
