Zenith Defy El Primero 21 Titanium 44mm

The Defy El Primero 21 measures hundredths of a second mechanically — its chronograph hand spins around the dial once every second, driven by a dedicated 50Hz escapement completely independent from the timekeeping train.

The skeletonized dial shows both systems at work inside a brushed titanium case. Half a century after inventing the automatic chronograph, this is Zenith proving the point again.
