While the design closely replicates the limited-edition model, it is important to note that this specific look is widely replicated. If you are verifying authenticity, pay close attention to the functional aspects of the movement. On an authentic piece, the sub-dials function explicitly as stopwatch chronograph counters, and the mechanical sweep of the second hand is smoothly driven by the automatic caliber. Counterfeit variations often swap this complex mechanism for an inexpensive quartz (battery-powered) movement where the sub-dials instead track basic calendar dates or 24-hour time.
