Since the Defy Extreme can measure time up to a one-hundredth of a second, Zenith ensured it could be done legibly. There’s a chapter ring on the rehaut that measures one to 100, and then there are the three sub-dials – chronograph minutes at three o’clock, chronograph seconds at six o’clock, and running seconds at nine o’clock. And unlike the conventional El Primero 400 and El Primero 3600, the date window has been benched.
